Are Training and Installation Mandatory for Class A, B, and C Tensile Testing Systems?
No. Training and installation are optional for our universal testing machines. Class A, B, and C systems ship with all required cabling and a step-by-step setup guide, so most labs complete installation independently.
A typical startup includes positioning the frame, making power and controller connections, attaching the load cell and any extensometer, installing the testing software, running the built-in self-check, confirming crosshead travel and safety circuits, and performing a trial test to validate data flow. The process is designed for technicians who may be new to UTMs, reducing ramp-up time without sacrificing measurement quality.
If you would like assistance, a qualified engineer can host a remote onboarding session to walk through connections, software configuration, grip selection, and your first live test. Onsite services can also be quoted on request. When your quality program calls for third-party verification, we can coordinate accredited calibration to ISO 7500-1 or ASTM E4 after the machine is operational.

Why Perform Material Fatigue Testing?
Fatigue testing quantifies how a material behaves under repeated loading across thousands to millions of cycles. It provides fatigue life, the number of cycles to failure at a given stress or strain, and helps define fatigue strength or an endurance limit. Laboratories use these results to compare heat lots, validate heat treatment or weld quality, evaluate notch sensitivity and crack initiation behavior, and select designs that match expected duty cycles and safety factors.
In a typical program, the specimen is cycled at a defined amplitude and mean level under force or strain control with a specified R ratio. Instruments track peak load, stiffness changes, and crack growth to produce S–N curves and, where applicable, strain-life or crack-growth data. Common references include ASTM E466 for force-controlled axial fatigue of metals, ASTM E606/E606M for strain-controlled fatigue, and ISO 1099 for metallic materials. Because loading fluctuates rather than remaining static, fatigue testing better reflects service conditions than single-pull tensile, bend, or compression checks, leading to more reliable durability predictions for real components.

TM-EML Series D UTM product page.
What Installation Space and Mounting Requirements Apply to TM-EML Series UTMs for Benchtop and Floor Models?
Benchtop units in the TM-EML Series should sit on a rigid, low-vibration workbench rated to carry the machine plus tooling. Typical footprints are 22.8 in × 20.4 in (580 mm × 520 mm) and about 238 lb (108 kg) for Series A, and 30 in × 25 in (770 mm × 640 mm) and about 595 lb (270 kg) for Series B. Leave 6–8 in (150–200 mm) behind the frame for cable routing and routine service, and keep both sides open to simplify grip and fixture changes.
Floor-standing Series C and Series D machines perform best on a flat, level concrete surface with vertical clearance for full crosshead travel and for load cell or grip changes. Larger Series D frames weigh roughly 2,200–13,000 lb (1000–6000 kg), so a reinforced slab is preferred. Bring the frame level and square using the leveling points or shims, and consider anchor bolts where the lab has floor vibration or when high-frequency cycling is planned. Provide front access for specimen loading, a safe path for a lift or pallet jack during placement, and space for the main power disconnect and cabling. If you are planning a first installation or relocating a unit, our team can review a floor plan to validate fit and workflow.
If you would like to review frame sizes and site planning notes, you can explore specifications on the
TM-EML Series D UTM page.
What Are the Power and Voltage Requirements for TM-EML Series UTM Models?
TM-EML Series A, B, and benchtop C operate on single-phase 220 V ±10%, 50/60 Hz. Typical input load is about 600 W for Series A, and roughly 1.0 to 1.5 kW for Series B and C depending on motor size and installed accessories. High-capacity Series D requires a three-phase 220 V ±10%, 50/60 Hz supply, with frame-dependent power from approximately 2 kW up to 11 kW.
For planning, Series A commonly suits a dedicated 15 A branch circuit, while Series B and C are often paired with 15 A to 20 A circuits. On Series D, estimated current draw spans about 6 A to 36 A per phase across the 2 kW to 11 kW range; actual values depend on drive settings, duty cycle, and power factor. Verify that the delivered voltage at the machine location is within 198 V to 242 V, and size the disconnect and overcurrent protection according to local electrical rules. If your facility provides 208 V or 240 V services, they fall within the stated tolerance band.
If you would like a deeper look at capacities and electrical ratings, you can review the specifications on the
TM-EML Series D UTM product page.
What Temperature, Humidity, Vibration, and Altitude Conditions Are Recommended for Stable Operation of TM-EML Series UTMs?
TM-EML systems perform best in a controlled laboratory. Keep room temperature stable at 60 to 77 °F (15 to 25 °C) during testing to reduce drift in force and displacement readings. Maintain low to moderate relative humidity, typically below 70 percent, and avoid any condensation within the test area.
Minimize vibration at the installation site. Benchtop frames operate well on a rigid laboratory bench, while large Series D frames should be mounted on a stable concrete floor slab. Separate the tester from heavy machinery and other sources of shock, particularly when using high-resolution extensometers or low-force load cells, which are more sensitive to ambient disturbance. If site vibration cannot be avoided, consider isolation pads or relocating the machine to a quieter room. Altitude is not usually a limiting factor for measurement accuracy, though labs at higher elevations may notice minor changes in pneumatic accessory response. In those cases, a small regulator adjustment typically restores expected grip timing and pressure behavior. If your facility has atypical conditions, our team can confirm compatibility with your setup.
If you would like to review specifications and options, you can read more on the
TM-EML Series C UTM product page.
What Utility Requirements Apply to TM-EML Universal Testing Machines With Pneumatic Grips or Environmental Chambers?
TM-EML load frames operate on electrical power only. The base machine does not need compressed air or external ventilation for motion control, data acquisition, or routine testing.
Air and ventilation are required only for certain accessories. Pneumatic grips run from a typical laboratory air line at 80 to 100 psi (5.5 to 7 bar). If plant air is not available, a compact oil-free compressor can be used, and clean, dry air is recommended for consistent clamping performance.
Environmental chambers carry their own utility needs. Depending on the model, a separate electrical connection and, in some cases, an exhaust pathway may be specified by the chamber supplier. These utilities belong to the chamber, not the TM-EML frame. If you plan to add pneumatic grips, a temperature chamber, or other powered accessories, share your accessory list and test range with our team so we can confirm utilities for your exact configuration.
If you would like to review frame capabilities and compatible accessories, you can learn more on the
TM-EML Series C UTM equipment page.
What Safety Features and Optional Protective Enclosures Are Available for TM-EML Universal Testing Machines?
TM-EML electromechanical UTMs include layered safeguards for routine tensile, compression, and flexural work. Standard protections include an emergency-stop button, upper and lower travel limits, motor overload protection, and automatic force shutoff when a specimen breaks unexpectedly. Optional guarding surrounds the test area with impact-resistant panels and allows safe, clear access to grips and fixtures; door interlocks and remote operation options are available when added risk reduction is desired.
During a test, the controller monitors load and position. If a sudden force spike or loss of load indicates a break, motion stops and the load path is protected, reducing the chance of shock to the load cell. Mechanical limit switches prevent crosshead over-travel, while overload logic pauses drive power before components are overstressed. Protective enclosures are recommended for brittle materials, sharp fragments, or high-energy failures. Clear panels maintain visibility, and hinged or sliding access keeps specimen changes practical. When equipped with an interlock, opening the enclosure halts crosshead motion and disables start commands until the guard is closed, helping operators maintain a safe standoff without sacrificing throughput.
If you would like to review safety functions and protective guarding options, you can learn more on the
TM-EML Series C UTM product page.
How Do TM-EML Universal Testing Machines Use Digital Closed-Loop Control and High-Speed Data Acquisition?
TM-EML load frames run a fully digital control loop that continuously reads force, crosshead displacement, and motor position, then updates drive output in real time. The high-speed data stream is time-aligned with GenTest software so you get live stress–strain curves, smooth transitions between control modes, and reliable results without waiting for buffers to catch up.
Measurement feedback comes from precision load cells and high-count encoders routed through high-resolution electronics. The controller applies tuned PID and feed-forward profiles to hold a commanded speed, load, or strain, which supports rate-sensitive methods such as ASTM E8 for metals or ISO 527 for plastics. When material behavior changes abruptly, for example at yield or during necking, the loop reacts immediately to stabilize the setpoint. The same control architecture is calibrated across the family, so Series A low-force machines and Series D high-capacity frames respond with consistent logic. Operators can set triggers, switch from displacement to load or strain at a defined event, and capture synchronized data for export without gaps.
If you would like a mid-range reference for capacities and controls, you can review technical details on the

Do TM-EML Series UTMs Integrate with LIMS, MES, and Third-Party Analysis Software?
Yes. TM-EML universal testing machines interface with external systems through GenTest export functions. Results, raw curve data, and calculated parameters can be written to CSV, Excel, or PDF, allowing straightforward transfers into LIMS, MES, or third-party reporting tools without custom programming.
GenTest can also produce tailored exports that match your file naming rules or batch structure, so receiving systems can map specimen IDs, lot numbers, and test metadata consistently. Many laboratories use automated import utilities on the LIMS or analytics side to ingest these files after each test run. If your workflow requires a specific column layout or additional identifiers, our team can help configure the export profile and confirm compatibility with your existing platforms.
If you would like to explore software and connectivity options, you can review capabilities on the
TM-EML Series D UTM product page.
How to Relocate a TM-EML Series Universal Testing Machine Within a Lab or Between Facilities, and What to Prepare First
Relocation depends on frame size. Benchtop TM-EML units such as Series A and Series B can be moved within a lab on a rated cart or with a controlled two-person lift. Floor-standing frames like Series C and Series D should be handled by trained riggers using certified lifting equipment, with the load frame secured to a pallet or base.
Before moving, power down, back up any test methods, lower and mechanically secure the crosshead, then remove grips, load cells, extensometers, fixtures, and any environmental chambers. Isolate electrical and pneumatic lines, cap ports, protect connectors, and wrap guide columns and screws to avoid contamination. Verify pathway clearances, doorway and elevator limits, and tie-down points, then stabilize the machine for transport to prevent tipping or frame shock. At the destination, place the system on a level surface, reconnect services, reassemble accessories, and confirm ambient conditions are suitable for testing. Perform a verification of force and alignment before resuming production testing, for example a force check to ASTM E4 or ISO 7500-1 and an alignment check to ASTM E1012, and record results for your quality program.
If you would like additional setup details and configuration options, you can review technical information on the
TM-EML Series C Universal Testing System page.
Which Alignment Tools and Procedures Prepare TM-EML Series UTMs for NADCAP or Similar Accreditation?
TM-EML testing frames support formal alignment workflows used for NADCAP and comparable audit programs. Operators can verify axiality with alignment fixtures compatible with ASTM E1012 and with ISO-aligned practices. These tools measure load-string symmetry, bending strain, and force distribution so you can adjust grips, adapters, and crosshead centering before a calibration visit. GenTest software guides stepped loading and captures alignment data, then generates a traceable report for auditors.
In practice, select an alignment bar or multi-gage fixture that matches your grip type, install it between the upper and lower adapters, and zero the sensors. Run a controlled tension profile in GenTest, add compression if required by your audit scope, and watch live axiality and bending indicators. If readings show eccentricity, correct grip parallelism, change or reface worn jaw faces, confirm adapter concentricity, and recenter the crosshead, then repeat the sequence until bending falls within your program limits. Save the GenTest protocol with operator ID, instrument serial numbers, and calibration references to document the alignment state. Our team can help match the correct alignment fixture to your frame and jaw style for a smooth audit.

What Is the TM-EML Series B UTM and What Applications Is It Designed For?
The TM-EML Series B is a dual-column benchtop electromechanical universal testing machine for mid-force tensile, compression, flexural, and peel testing up to 2,250 lbf (10 kN). Its higher frame stiffness and wider working space support repeatable loading in laboratories and production environments where stable force application matters.
Typical use cases include plastics and composites for tensile and flexural programs, small cross-section metals, elastomers, rigid polymers, construction materials, and structural subcomponents. Labs often pair this platform with interchangeable grips and fixtures to run standard methods such as ASTM D638 or ISO 527 for plastic tensile tests, ASTM D790 or ISO 178 for flexural tests, ASTM D695 for compression on rigid plastics, ASTM D903 for peel, and ASTM E8 for metals when specimen geometry fits the capacity. The configuration fits routine quality control, R&D exploration, and engineering validation work, while the generous test space helps streamline specimen changeover and extensometer placement to maintain throughput across batches.
If you would like to review capacities, common test methods, and compatible fixturing, you can explore details on the
TM-EML Series B Universal Testing System.
Which Materials and Specimen Types Suit the TM-EML Series B Mid-Force UTM?
Series B is designed for laboratories that handle mixed materials on one frame where a stiffer structure is preferred over low-force machines. Suitable samples include rigid plastics and engineering polymers, small metallic parts and fasteners, composite laminates, glass-fiber or carbon-fiber coupons, elastomers, pressure-sensitive adhesives, foams, thin films, and general structural test coupons.
The system accommodates common specimen geometries for tensile, compression, flexural, peel, shear, and puncture methods using dog-bone, rectangular bar, strip, and lap-joint formats. Typical standards include ASTM D638 or ISO 527 for plastics, ASTM E8 for small metal components, ASTM D3039 for composites, ASTM D790 for flexural bars, ASTM D1876 for T-peel, ASTM D1002 for single-lap shear, and puncture testing of films per ASTM F1306. With appropriate grips and fixtures, operators can move between material families in minutes, sustain throughput, and produce consistent results across shifts.
If you would like to compare load frame options and specimen compatibility, you can review technical details on the
TM-EML Series B UTM product page.
What Load Capacities Are Offered For TM-EML Series B UTM And How Do I Choose The Right Rating?
TM-EML Series B covers 22 lbf to 2248 lbf (100 N to 10 kN), addressing mid-force applications that benefit from a stiffer benchtop frame and higher load capability than low-force systems.
Select the capacity by matching it to your typical specimen failure load, not the absolute maximum you might ever see. For most plastics, composites, elastomers, and small metal components, target peak forces that use about 10 to 70 percent of the load cell range to maintain resolution without frequent overload trips. If your expected peaks are near the top of that band, step up one capacity so routine tests still fall well within range while leaving headroom for variability.
Example: if parts usually fail at 1,000 lbf (4.45 kN), a 2,000 lbf (8.90 kN) configuration provides stable readings and reduces nuisance stops. Consider the highest accessory grip force and fixture mass as part of your selection, especially for compression or cyclic work, since those can add to measured load. When multiple test types are planned, choose the capacity that best fits the most common specimens, then add a secondary load cell for occasional low-force or higher-force methods.

TM-EML Series B UTM on the product page.
What Are the Dimensions, Test Space, and Weight of the TM-EML Series B Dual-Column Universal Testing Machine?
The Series B dual-column benchtop frame occupies 26.8 in × 18.5 in (680 mm × 470 mm), provides a 16.5 in (420 mm) working width, and offers 42.9 in (1090 mm) of maximum crosshead travel. The complete frame weighs about 198 lb (90 kg).
This compact footprint fits standard laboratory benches while leaving room for a PC and pneumatic controls. The 16.5 in (420 mm) gap accommodates common grips, fixtures, and load trains used for metals, polymers, and composites. With 42.9 in (1090 mm) of crosshead travel, operators can position extensometers, compression platens, or flexural jigs without reconfiguring the setup, which shortens changeovers and helps keep the load train aligned. At 198 lb (90 kg), the frame remains stable for precise measurements yet is manageable for bench installation or relocation within the lab.

TM-EML Series B Universal Testing Machine.
How Does the Dual-Column Benchtop Frame Compare With Single-Column TM-EML Models?
The dual-column benchtop configuration in the TM-EML Series B provides 42.9 in (1090 mm) of vertical crosshead travel and a 16.5 in (420 mm) test width between columns, with an overall frame size of 30.3 × 25.2 × 66.9 in (770 × 640 × 1700 mm). Compared with single-column TM-EML machines, the twin-post layout offers higher lateral stiffness, a wider, symmetrical test space, and added clearance for compression, flexural, and large-grip tensile setups. Single-column units focus on a compact footprint and open-front access that suits lighter-force tensile work and narrow fixtures.
Usable working stroke depends on grips, fixtures, extensometers, and any environmental chamber mounted on the frame. Most labs reserve a portion of the 42.9 in (1090 mm) travel for alignment and preload, then use the remaining stroke for test execution. If you regularly run wedge or pneumatic grips, long axial extensometers, or chamber testing, the dual-column’s 16.5 in (420 mm) clearance helps maintain alignment and reduces off-axis motion. If bench space is limited and specimens are short or narrow, a single-column TM-EML may offer faster changeovers in a smaller footprint. The Series B frame still fits comfortably on a robust bench or a dedicated stand.

What Are the Crosshead Travel, Working Width, and Usable Test Area on TM-EML Series B UTM?
The TM-EML Series B provides a vertical crosshead travel of 42.9 in (1090 mm) and a working width of 16.5 in (420 mm). This gives a usable test area roughly 42.9 in high by 16.5 in wide (1090 mm × 420 mm). Actual clearance depends on the installed grips, adapters, extensometers, and any environmental chamber, so the effective vertical space between fixtures may be reduced by their mounted height.
For context on motion capability, the machine covers crosshead speeds from about 0.000002 in/min (0.00005 mm/min) up to 78.7 in/min (2000 mm/min), with a maximum return speed of 94.5 in/min (2400 mm/min). Speed accuracy stays within ±0.2 percent of the set value, managed by a 24-bit digital controller operating at 1200 Hz. This combination supports ultra-slow quasi-static or creep-style procedures as well as faster throughput work, and with the position encoder the system can hold low strain rates near 0.00007 s^-1, subject to gauge length and test method.

TM-EML Series B UTM product page.
What Speed Range and Strain-Rate Control Does the TM-EML Series B UTM Offer?
Crosshead speed spans from 0.00005 in/min to 78.7 in/min (0.00005 to 2000 mm/min), with return speed up to 94.5 in/min (2400 mm/min). Speed accuracy holds within ±0.2 percent across the full range, driven by a high-resolution digital controller.
This range supports steady low strain rates for quasi-static testing and also accommodates faster production routines. Closed-loop servo control with fine encoder feedback maintains stable setpoints at minimal speeds, helping avoid overshoot during ramp and hold segments. When paired with an extensometer, the system can control by strain rate for methods that specify it, such as ASTM E8 for metals or ISO 527 for plastics, while crosshead-speed control remains available for procedures that call for displacement-based settings. Operators may program rate changes by segment, capture transitions cleanly, and return quickly between specimens to improve throughput without compromising data quality.

TM-EML Series B UTM product page.
What Load Cell Options Are Available for TM-EML Series B, and Can Multiple Load Cells Be Interchanged?
TM-EML Series B supports interchangeable load cells from 22 lbf to 2248 lbf (100 N to 10 kN). Each sensor ships calibrated and includes a digital ID, so when a new cell is connected the controller recognizes it and switches to the correct capacity and calibration without extra setup.
This span covers delicate elastomers and plastics through mid-force composites and small metallic coupons. Swapping between low and mid capacities lets labs capture high resolution for soft materials, then move to higher capacity for stronger specimens on the same frame. The electronics read the sensor identification, apply the stored calibration file, and update limits, resolution, and break protection for the selected cell. This workflow is useful when running mixed queues such as ASTM D638 plastics alongside small-section metals under ASTM E8. Because calibration data resides with the load cell, you do not need to reconfigure methods or perform manual scaling between changes, which helps maintain data quality and shortens turnaround.
If you would like more details on capacities, electronics, and accessories, you can review specifications on the
TM-EML Series B UTM product page.
How Does the TM-EML Series B UTM Protect Delicate or Brittle Specimens During Gripping and Preload?
The TM-EML Series B applies low-speed approach with soft-start crosshead motion, paired with low-force preload control and continuous force feedback. This combination limits abrupt load spikes when clamping brittle plastics, composite strips, or thin rigid coupons. If resistance rises unexpectedly, the drive stops automatically to avoid overstress during alignment.
During setup, operators can select gentle jog rates, ramp the crosshead from zero to the target approach speed, and set a preload threshold that caps initial clamping force. The controller samples load in real time, compares it to growth limits, and triggers a stop or hold if the trend exceeds the configured rate. Position-first sequences let the jaws touch under minimal load, then transition to force-based seating, which protects notches and machined radii. These behaviors support careful gripping workflows used with methods such as ASTM D638 and ISO 527 without slowing specimen throughput.
If you would like a deeper look at these safeguards, you can review motion and safety features on the
TM-EML Series B Universal Testing Machine page.
Which Extensometers and Strain Measurement Options Are Compatible With TM-EML Series B UTM?
TM-EML Series B supports clip-on extensometers for plastics and composites, long-travel devices for elastomers, and high-accuracy units for small metallic specimens. It also works with non-contact laser or video systems when high elongation, no physical attachment, or environmental chamber testing is required. All devices connect through the GenTest software interface, and their calibration factors can be stored with the test method for repeatable setup.
In practice, clip-on instruments are common for ASTM D638 or ISO 527 plastics and composite coupons, long-travel models track elastomers per ASTM D412, and precision clip-on or miniature devices capture modulus and yield for metals following ASTM E8. Non-contact video or laser systems avoid mass loading on delicate samples, help with testing to break, and support temperature-controlled or submersion fixtures. GenTest provides zeroing, gauge length entry, channel scaling, and live strain display so operators can move between devices without changing the frame configuration. When grips, chambers, or other accessories are added, the extensometer channel remains addressable through the same interface for consistent data across batches.
If you would like to review specifications and compatible extensometry, you can read more on the
TM-EML Series B Universal Testing Machine page.
Is a Protective Safety Enclosure Available for the TM-EML Series B Dual-Column UTM?
Yes. A full protective enclosure is available for the TM-EML Series B dual-column system. It surrounds the test space with clear, impact-resistant panels and a rigid frame, providing visibility while containing fragments from brittle failures. Front and side access points let operators reach grips and fixtures without removing the shield.
Laboratories running brittle materials, composite coupons, or rigid plastics often choose this option, especially for programs aligned with ASTM D3039 or ASTM D638. The enclosure can be supplied with an electronic door interlock that blocks crosshead motion and grip actuation when a door is open, then allows operation only after it is latched. This configuration supports EHS policies in labs with higher-risk failure modes or shared workspaces, and it helps reduce cleanup and downtime after shattering events. The enclosure integrates cleanly with Series B accessories and maintains clear sightlines for alignment and instrumentation.
If you would like to review enclosure and interlock options, you may explore details on the
TM-EML Series B Universal Testing Machine page.
Can the TM-EML Series B UTM Include an Industrial Touchscreen PC, and Can It Run Without a Dedicated Workstation?
Yes. The TM-EML Series B can be supplied with an integrated industrial touchscreen PC for a compact, all-in-one setup. In this configuration you have full access to GenTest for method setup, guided test execution, live graphing, and automated reporting.
If you prefer to use existing hardware, the machine operates the same way from an external PC or laptop. Connect via USB or Ethernet, install GenTest, and you get identical control, data acquisition, and report outputs. Many labs select this path to standardize software on their IT image or to keep the PC off the benchtop.
When no workstation is present, the included handheld remote with a 3.5 in (89 mm) color touchscreen supports jog, crosshead positioning, grip control, and starting predefined methods. For creating or editing methods, batch analysis, and formal report generation, running GenTest on a PC is recommended. This flexibility lets you match the control approach to your workflow, whether you are running quick checks at the frame or operating the system from a networked workstation.
If you would like to compare control options or review specifications, you can explore configuration details on the
TM-EML Series B UTM product page.
How Fast Can Grips, Fixtures, and Load Cells Be Changed on the TM-EML Series B UTM?
Most grip bodies and fixtures on the Series B can be swapped in a few minutes. The open-front test space and quick-mount interfaces provide direct access to the load string, so operators transition between setups with minimal tools. Load cells are also changed quickly because the sensors include TEDS digital identification, which lets the controller recognize the connected capacity automatically without manual calibration entry.
In practice, changeover typically involves returning the crosshead to a safe position, unloading the frame, releasing the quick pin or threaded adapter, removing the current grip, then installing the alternate jaws or fixture and re-zeroing force. When a different load cell is plugged in, the TEDS chip prompts the software to load the stored calibration and limits, reducing input steps and cutting the chance of parameter errors. This workflow is helpful when moving from tensile grips to a three-point bend fixture for methods such as ASTM D790, or when switching to a lower-capacity sensor for thin films or wires. The result is less downtime between batches and a smoother routine for QC, R&D, and teaching labs.
If you would like to review configuration options for faster changeovers, you can explore details on the
TM-EML Series B Universal Testing Machine page.
How Does the TM-EML Series B UTM Manage Standard Test Methods and Templates in GenTest?
GenTest on the Series B machine includes a comprehensive library of templates for ASTM, ISO, EN, and GB/T tensile, compression, flexural, and peel tests. Each template preloads control mode, crosshead speed, strain or extension limits, data channels, and calculations, so you can run to the selected standard with minimal setup. Examples include ASTM E8 and ISO 527 for tension, ASTM D790 for flexural, and ASTM D1876 for peel.
In daily work, an operator selects a template, enters specimen dimensions, and starts the sequence. GenTest stores methods locally, so switching between templates typically takes only a few seconds during high-throughput batches. When a geometry or workflow deviates from a published method, you can clone a template, adjust parameters such as speed, preload, break criteria, sampling rate, and reporting fields, then save it as a lab method. The software keeps related calculations, including yield, modulus, and ultimate values, linked to the chosen method to avoid manual spreadsheet steps. This behavior supports repeatable setup across shifts and simplifies audit preparation without locking you into a single material family.
If you would like to review software features and typical workflows, you can learn more on the
TM-EML Series B UTM product page.
What Are the Position, Speed, and Force Resolutions on the TM-EML Series B UTM?
Position resolution is 0.00043 mil (0.011 µm). Crosshead speed accuracy is ±0.2 percent across the operating range. Force resolution is 1 part in 600,000 of full scale.
A high-precision encoder with digital closed-loop feedback lets the dual-column frame register very small displacement changes during tensile, compression, or flexural routines, even at very low speeds. This level of motion control supports slow quasi-static rates for yield characterization while keeping higher throughput checks stable and repeatable. The load measurement electronics detect subtle load shifts, such as seating effects, toe-compensation regions, or the early onset of necking, yet still accommodate mid-force specimens. Together, these capabilities produce clean stress-strain curves, consistent strain-rate control, and dependable identification of small events like grip slippage or microcracking.
If you would like more detail on motion control and measurement performance, you can review technical specifications on the
TM-EML Series B UTM product page.
How Does the Pneumatic Grip Control Module Work on TM-EML Series B Universal Testing Machines?
The optional pneumatic module connects to the TM-EML Series B controller and supplies regulated air to compatible pneumatic grips. Operators can open and close the jaws from frame-mounted controls or through the GenTest software. The system holds the selected clamping pressure and stabilizes automatically before loading begins.
During setup, the operator selects a pressure setpoint in the interface. The module verifies air availability, pressurizes both jaws evenly, and maintains the set value through preload and the test, helping reduce slippage on composites, rigid plastics, elastomers, and laminated specimens. This behavior supports repeatable gripping for methods such as ASTM D638 and ISO 527 when applicable.
Grip state feedback is tied to the Series B safety logic. Crosshead motion is blocked until the grips report a closed and stable condition, which helps protect specimens, grips, and the machine during test initiation.
If you would like broader details about this option and compatible grips, you can review features and specifications on the
TM-EML Series B UTM product page.
What Reporting and Data Export Options Does the TM-EML Series B UTM Provide?
TM-EML Series B systems use GenTest to deliver a complete reporting suite with immediate post-test review and flexible output formats. Users can generate PDF reports, export numeric tables to Excel or CSV, and save curve images as PNG or JPG. Reports may be created from default templates or from custom layouts tailored to QC or R&D documentation.
After each test, operators can review stress–strain curves, calculated parameters, specimen metadata, and operator inputs directly on screen, then publish a report in a single step. Batch reporting compiles multiple specimens run under the same method into one file to speed lot disposition. Template-based exports keep document structure consistent across repeated programs, while CSV or Excel files support LIMS or MES workflows and downstream statistical analysis. Curve images provide quick sharing when a full report is not required.
If you would like a closer look at templates, batch reporting, and export formats, you can review these features on the
TM-EML Series B UTM product page.
Can the TM-EML Series B UTM Run Ultra-Low Strain Rate and Micro-Displacement Tests?
Yes. The TM-EML Series B electromechanical UTM supports ultra-low strain rate and micro-displacement testing through high-resolution encoder feedback and closed-loop servo control.
It maintains smooth motion and stable load and displacement signals at extremely slow crosshead speeds, which is useful for time-dependent deformation studies, creep-style loading, slow polymer strain development, adhesive characterization, and delicate quasi-static steps. When equipped with low-capacity load cells, the frame improves force resolution for small signals. Long-travel or non-contact extensometers can be added to capture minute displacement or strain without adding mass to the specimen. The control software provides constant strain rate, constant displacement, step-and-hold, and ramp-dwell profiles so you can run micro-movement sequences with repeatable results. Proper fixturing and, when needed, environmental controls further help stabilize readings during long-duration tests.
If you would like to explore configurations for micro-movement applications, you can review capabilities on the
TM-EML Series B UTM product page.
Can the TM-EML Series B UTM Integrate With External Sensors, Environmental Chambers, or Custom R&D Accessories?
Yes. The dual-column Series B integrates with external sensors and accessories through the GenTest control platform or by installing devices in the load string. Laboratories commonly connect extensometers, displacement transducers, temperature probes, environmental chambers, pneumatic grip controllers, and custom fixtures for R&D workflows.
Accessories can be mounted to the crosshead or base using adapter plates, grip couplings, or chamber pass-throughs, without affecting closed-loop control. GenTest can log auxiliary channels alongside force and travel, apply start or stop triggers, and use extensometer feedback for strain control. TEDS-capable sensors are recognized for quick setup, and our team can provide interface drawings and adapter hardware for unique geometries. If a chamber or sensor requires electrical or safety interlocks, the controller I/O can coordinate door switches and temperature dwell steps within the test method.
If you would like to map out a multi-sensor setup, you can review integration options on the
TM-EML Series B Universal Testing Machine page.
Does the TM-EML Series B UTM Support Cyclic, Multi-Stage, Creep, Relaxation, and Custom Loading Profiles?
Yes. With GenTest software, the TM-EML B-Series runs cyclic, multi-stage, creep, stress-relaxation, and fully custom sequences under load, displacement, or strain control.
Operators can chain ramps, holds, rate changes, and recovery segments, then loop any block by count or by time, extension, or stability criteria. Segment transitions provide smooth ramping for sensitive specimens, while conditional stops on force drop or limit travel help protect load cells and grips. Methods can be saved as reusable templates and applied across different materials or batches for consistent workflows. Common use cases include low-cycle fatigue screens, step-loading studies for plastics and composites, and multi-speed tensile procedures used in research. For time-dependent behavior, GenTest supports creep per plastics methods such as ASTM D2990 and stress relaxation routines consistent with practices like ASTM E328 when suitable for the material and fixturing.

How Does the TM-EML C-Series Dual-Column Frame Improve Stiffness and Alignment vs Single-Column, Lower-Capacity Models?
The C-Series dual-column frame delivers higher structural stiffness and more stable load-string alignment than single-column and lower-capacity TM-EML machines, especially at elevated forces and with long-travel fixtures.
Twin columns with synchronized, preloaded ball screws and dual guide rails distribute bending moments across both uprights, which reduces lateral deflection and crosshead rotation. A reinforced crosshead and wider column spacing help keep platen or grip faces parallel across a larger work zone, supporting heavier grips, long extensometers, or environmental accessories without introducing meaningful side load. With rated capacities up to 11,240 lbf (50 kN), the C-Series maintains alignment during cyclic profiles and when testing metals or advanced composites where modulus, yield, and tensile strength accuracy depend on low frame compliance.
Single-column and smaller-capacity frames are compact and efficient for lower forces, typically up to 2,248 lbf (10 kN), yet their single load path and narrower stance make them more sensitive to off-center loading and heavy fixturing, which can affect strain uniformity and break location. Labs that verify alignment to ASTM E1012, or run high-precision tensile methods such as ASTM E8 or ISO 6892-1, often select the C-Series geometry to achieve repeatable results across a wider range of specimens and accessories.
If you would like to compare frame architecture and capacities, you can review technical details on the
TM-EML Series C UTM product page.
How Does the Pneumatic Grip Control Module Work on the TM-EML Series C UTM and What Are the Workflow Benefits?
The optional pneumatic grip control module provides closed-loop, digital pressure regulation for the upper and lower grips on the TM-EML Series C. Operators set and monitor clamping pressure from the handheld console or directly in GenTest software, with independent channels for each grip. An integrated electronic regulator maintains the target pressure during the test, and quick-connect air ports make it straightforward to attach pneumatic side-action grips or other air-operated fixtures for tensile or compression work.
For routine testing, this module improves repeatability by applying the same clamping force every time, which reduces operator-to-operator variation and helps protect delicate or compliant specimens from over-tightening. Preset profiles let labs switch materials or jaw faces without re-tuning pressure, which shortens changeovers and speeds batch throughput. Built-in safety logic ties grip actuation to machine state, so clamping remains disabled until the test space is clear and the frame is ready, helping prevent unintended jaw movement during setup.
If you would like to review control options, pressure presets, and compatible pneumatic grips, you can learn more on the
TM-EML Series C Universal Testing System page.
How Do I Select Load Capacity and Test Speed for an Electro-Mechanical Universal Testing Machine?
Start with the highest expected specimen load. Estimate peak force by multiplying ultimate tensile strength by the smallest cross section, then choose a frame rated 2 to 3 times higher. Common ranges are 10 kip, 30 kip, and 60 kip (45 kN, 135 kN, and 267 kN). For thin plastics, elastomers, or biomedical parts, 225 lbf to 1,000 lbf (1 kN to 4.4 kN) often suffices.
Match control mode and speed to materials and methods. For metals to ASTM E8 or ISO 6892-1, prioritize strain or strain-rate control with an extensometer, not crosshead speed alone. A practical speed envelope is 0.002 to 20 in/min (0.05 to 500 mm/min); labs running plastics to ASTM D638 or ISO 527 often need up to 40 in/min (1,000 mm/min). Verify rate accuracy of ±0.5 percent and position resolution near 0.00004 in (1 µm) for consistent results.
Use interchangeable load cells so routine tests fall between 10 percent and 90 percent of capacity. For example, pair a 10 kip (45 kN) cell for structural metals with a 500 lbf (2.2 kN) cell for thin polymers or adhesives. Select grips rated above the expected test load and an extensometer with the correct gauge length, such as 1.0 in or 2.0 in (25 mm or 50 mm), to meet specimen geometry and relevant standards.
If you would like specification guidance tailored to your lab, you can review options on the
UTM Electro Mechanical equipment page and connect with our team for configuration details.
How Do I Select Load Capacity, Travel, and Speed for an Electromechanical UTM?
Start by estimating the highest force your specimens will require, then size the frame at 1.2 to 1.5 times that peak. For example, if trials show 8,000 lbf (35.6 kN), a 10,000 to 15,000 lbf (44.5 to 66.7 kN) machine provides headroom for tough batches, larger cross sections, or future programs. Verify the load cell meets Class 1 or better accuracy per ASTM E4 or ISO 7500-1, and confirm resolution is adequate for low-force segments like yield-by-offset.
Match speed and control to your methods. A practical range is roughly 0.002 to 20 in/min (0.05 to 500 mm/min), with stable closed-loop control at very low speeds for modulus, creep, or stress-relaxation work. If you run strain-rate or crosshead-rate procedures in ASTM E8, ISO 6892-1, or ISO 527, ensure the controller supports constant strain rate and easy transitions between method steps. Choose travel that accommodates grips, extensometers, and anticipated elongation; 20 in (510 mm) covers most metals and plastics, while high-elongation materials may need 30 to 40 in (760 to 1,020 mm).
Evaluate the ecosystem. Confirm data acquisition at 1,000 Hz or higher for clean stress-strain curves, compatibility with clip-on or non-contact extensometry, and the availability of tension, compression, and flexure fixtures. Consider safety, power, and lab footprint, for example 120 V single-phase or 230 V single-phase, and plan for calibration and verification intervals aligned to your quality system.

Contact Us page.
How Do I Choose the Right Electromechanical UTM Capacity and Speed?
Start with capacity. Estimate the highest failure load for your specimens, then select a frame rated at 1.2 to 2.0 times that value to preserve measurement linearity and accommodate grips or chambers. Size the primary load cell so typical peaks fall between 50 and 90 percent of capacity. If you also test thin plastics or small wires, add a secondary load cell, for example 50 lbf to 500 lbf (220 N to 2.2 kN). As a reference, if most metal samples break near 8,000 lbf (35.6 kN), a 10,000 to 20,000 lbf (44.5 to 89 kN) frame with a 10,000 lbf (44.5 kN) load cell is a practical choice.
Confirm speed and travel next. A crosshead speed range covering 0.002 to 20 in/min (0.05 to 500 mm/min) addresses common plastics methods in ASTM D638 and ISO 527, and metals preloads or modulus ramps. Plan for at least 30 in (760 mm) vertical travel when using long extensometers, temperature chambers, or long-specimen grips. Look for closed-loop control in force, displacement, and strain, along with high-resolution position feedback and adequate data rates for your material behavior.
Validate compliance and accessories. For metals, verify force calibration to ISO 7500-1 Class 1 or Class 0.5 and ASTM E4, and consider an alignment device per ASTM E1012 for ASTM E8 or ISO 6892-1 testing. Match grips to the application, such as wedge or hydraulic grips for metals and pneumatic grips for thin plastics, and select a clip-on or automatic extensometer meeting ASTM E83 Class B-1 or better.

How Do I Select Load Capacity, Speed, and Extensometry for an Electromechanical UTM?
Start with the highest expected failure load and specimen dimensions. Choose a frame capacity that covers your peak load with 20 to 30 percent headroom. Use interchangeable load cells so routine tests run between 10 and 90 percent of the cell’s capacity. For example, if aluminum coupons fail near 12 kip (53 kN), a 22 kip (100 kN) machine with a 22 kip cell plus a secondary 2 kip (10 kN) cell delivers both headroom and fine resolution. Typical electromechanical systems span about 225 lbf to 220 kip (1 kN to 1000 kN).
Match speed capability to your methods. For metals guided by ASTM E8, prioritize low-speed stability and closed-loop strain control for yield and modulus work. For plastics under ASTM D638 or ISO 527, ensure the controller holds constant rates across roughly 0.2 to 20 in/min (5 to 500 mm/min), with speed accuracy near ±0.5 percent of setpoint and smooth transitions between preload, approach, and test segments.
Select extensometry by gauge length, travel, and class. Metals often use clip-on units at 2 in (50 mm) that meet ASTM E83 Class B1 or better; plastics frequently require 1 in to 2 in (25 mm to 50 mm) gauge lengths and ISO 9513 Class 1. Plan for total travel of about 1 in (25 mm) for metals and up to 4 in (100 mm) or noncontact video for high-elongation materials. Confirm lab conditions and utilities, such as 59 to 86 °F (15 to 30 °C) and 120 V or 230 V power, align with your testing plan.
If you would like to discuss sizing and configuration, you can connect with our team on the
Contact Us page.
How Do I Choose Load Cell Capacity For An Electromechanical UTM?
Start by estimating the highest force your specimens will generate. Multiply the expected ultimate tensile strength in psi by the smallest cross-section in in² to obtain force in lbf, then convert to kN as needed. Account for worst-case conditions such as elevated strength after heat treatment or thicker sections, and include typical fixture weight if it contributes to force measurement.
Select a capacity that keeps routine tests within about 20% to 80% of the load cell rating. Many systems achieve Class 1 or Class 0.5 accuracy per ASTM E4 or ISO 7500-1, typically ±1% or ±0.5% of reading from roughly 0.2% to 100% of capacity. If your workload spans small plastics to high-strength metals, use multiple interchangeable cells, for example 1,000 lbf (4.45 kN) for thin coupons and 10,000 lbf (44.5 kN) or 50,000 lbf (222 kN) for stronger parts, with auto-recognition to prevent setup errors.
As a quick example, a strip with 0.25 in² area and 60,000 psi UTS requires about 15,000 lbf (66.7 kN). A 20,000 lbf (89 kN) cell places testing in the optimal range. Confirm the frame’s maximum capacity exceeds the largest cell, apply a 30% to 50% safety margin, and verify force at least annually or after relocation or suspected overload using ASTM E4 or ISO 7500-1 procedures. Avoid near-capacity sustained loading, off-axis forces, and impact; use proper grips and alignment to protect the cell and maintain measurement fidelity.

Contact Us page for guidance.
How Do I Choose Grips And Extensometry For A 2,248 lbf (10 kN) Benchtop UTM?
Match the grip style to the specimen and failure mode. For plastics coupons per ASTM D638 or ISO 527, use wedge or pneumatic grips with serrated or rubber-faced jaws sized to 1 in or 2 in (25 mm or 50 mm) to prevent slip without crushing. Thin sheets and soft alloys per ASTM E8 benefit from self-tightening wedge grips; small wires and fibers are best held with V-jaw wedges or capstan grips. For compression, use parallel platens, typically 2 in to 4 in (50 mm to 100 mm) diameter, with spherical seats when alignment is critical.
Select extensometry for the strain range and standard. Metals work well with axial clip-on extensometers meeting ASTM E83 class requirements at 2 in (50 mm) gauge length. Plastics often require longer travel or 1 in to 2 in (25 mm to 50 mm) gauge lengths. Elastomers and films per ASTM D412 benefit from non-contact video or high-elongation extensometers to avoid grip influence.
This system supports interchangeable bidirectional load cells so one frame can run tensile and compression. Choose a load cell that places peak force between 10% and 90% of capacity across 22.5 lbf to 2,248 lbf (0.1 kN to 10 kN). The wide speed range, about 0.000002 to 79 in/min (0.00005 to 2000 mm/min) with 94.5 in/min (2400 mm/min) return, and tall travel of 42.9 in (1090 mm) help accommodate long specimens and high-elongation tests. For audit-driven alignment, consider an alignment fixture to support ASTM E1012 and NADCAP readiness.
If you would like to review accessories and specifications in context, you can explore the
TM-EML Series B UTM on the product page.
How Do I Choose Load Cells And Extensometers For A 10 kN Benchtop UTM?
Select a load cell so the expected peak force falls between about 10 percent and 90 percent of its capacity. For thin films, elastomers, and small components, a 22 lbf (100 N) sensor preserves low-force resolution. For metals or composites approaching the frame limit, a 2,248 lbf (10 kN) sensor covers higher loads while maintaining accuracy. If your program spans very different force levels, plan on two interchangeable cells and verify calibration per ASTM E4 or ISO 7500-1 intervals that match your quality plan.
Match the extensometer to material behavior and the standard. For metals per ASTM E8, common gauge lengths are 2.0 in (50 mm) or 1.0 in (25 mm) with appropriate travel for yield and uniform elongation. For plastics per ASTM D638 or ISO 527, use long-travel clip-on or non-contact video extensometry to capture strain through large elongations, often exceeding 100 percent. For modulus studies on stiff materials, a small-range, high-resolution unit improves Young’s modulus repeatability.
Grip selection protects the sensor and specimen. Use self-tightening wedges for sheet and plate, pneumatic grips for films and textiles, and compression platens or three-point fixtures for compressive and flexural work. Keep jaw face selection consistent with surface hardness to minimize slippage. Quick-change adapters and auto-recognition of transducers, when available, reduce setup time and help prevent capacity mismatch between grips and the installed load cell.
If you would like an overview of capacity options, extensometry, and software integration, you can review technical details on the
TM-EML Series B UTM product page.
What Load Cell, Grip, And Extensometer Setup Is Best For A 10 kN Benchtop UTM?
Select load cells so your expected peak force falls between roughly 10% and 90% of the sensor’s capacity. For a lab testing thin plastics, foils, and light metals, a practical set is 50 lbf (220 N), 500 lbf (2.2 kN), and 2,248 lbf (10 kN). This coverage maintains resolution for low-force work while keeping headroom for stronger materials. If your program spans adhesives, elastomers, and small metals, consider two cells at minimum, for example 100 lbf (445 N) and 1,000 lbf (4.45 kN).
Match grips to material behavior, not just strength. For plastics per ASTM D638 or ISO 527, use pneumatic vise grips with controlled pressure around 20 to 80 psi (138 to 552 kPa) to prevent jaw breaks and slippage. For metallic coupons per ASTM E8, wedge grips with appropriate jaw faces, serrated or smooth, deliver consistent clamping as load rises. Use capstan or bollard grips for wires and fibers, and a lap-shear fixture for adhesives per ASTM D1002.
Choose extensometry based on strain range and surface finish. Clip-on devices suit low to moderate elongation with common gauge lengths such as 1.0 in (25 mm) or 2.0 in (50 mm). For high-elongation elastomers or thin films, non-contact video extensometers avoid mass loading. When tight metals data or NADCAP audits are in scope, add an alignment fixture and verify bending per ASTM E1012, targeting ≤5% bending strain at representative forces, for example 100 to 1,000 lbf (445 to 4,450 N). Crosshead speed should follow the applicable standard, often within 0.02 to 20 in/min (0.5 to 500 mm/min).

Which Grips And Extensometers Work Best For Thin Sheet, Foil, And Wire On A 10 kN Universal Testing Machine?
Thin or smooth materials tend to slip, so use wedge or self-tightening grips sized to your expected peak load. Pneumatic wedge grips with rubber-coated or diamond-serrated faces deliver consistent clamping from about 50 to 2,200 lbf (0.2 to 10 kN). For sheet, choose jaw widths near 1.0 in (25 mm) with face textures matched to the surface finish. For wire and small rod, V-jaws or collet-style inserts covering 0.01 to 0.25 in (0.25 to 6.4 mm) diameters help keep the sample centered and prevent torsion.
If you are configuring fixtures and strain measurement options, you can review technical details on the
TM-EML Series B UTM equipment page.
How Should I Select Load Cell Capacity And Crosshead Speed On A 10 kN Electromechanical UTM?
Select a load cell that keeps your expected peak force between about 10 and 90 percent of its rating for best accuracy. For films, foils, and elastomers that rarely exceed 20 lbf, use 22.5 lbf (0.1 kN) or 45 lbf (0.2 kN). For molded plastics and adhesives, 225 lbf (1 kN) or 450 lbf (2 kN) provides resolution without saturating the sensor during yield. For thin metals and wires following ASTM E8 or ISO 6892-1, 1124 lbf (5 kN) is common, with 2248 lbf (10 kN) reserved for stronger alloys or larger cross sections. This approach minimizes range changes mid-test and improves repeatability across operators.
Set crosshead speed to match the required strain rate or speed in the method. Plastics under ASTM D638 or ISO 527 often use slower modulus segments and higher speeds near yield, which the machine supports from 0.000002 to 78.7 in/min (0.00005 to 2000 mm/min). High return moves up to 94.5 in/min (2400 mm/min) reduce cycle time. Long-elongation samples benefit from generous travel at 42.9 in (1090 mm) and test width of 16.5 in (420 mm) to accommodate grips and extensometers.
Pair capacity and speed with proper fixturing. Use capstan or pneumatic grips for thin films, wedge grips for plastics and metals, and the appropriate extensometer class to meet accuracy requirements. Verify rate segments and strain measurement per the governing standard before production release.

TM-EML Series B UTM product page.
How Do I Choose Between Electromechanical and Hydraulic UTMs for Tensile Testing?
Start with the highest load you actually run. If routine work stays below about 50,000 lbf (220 kN), an electromechanical frame gives precise rate control and stable low-speed testing, down to roughly 0.002 in/min (0.05 mm/min). That behavior helps meet method-defined strain rates for plastics and elastomers under ASTM D638 or ISO 527, and for thin metals that need tight crosshead control.
Heavy sections of steel, rebar, or high-strength alloys often push past 110,000 lbf (500 kN). A hydraulic frame handles these forces with margin and can reach 2,000,000 lbf (9 MN) when required for ASTM E8/E8M or ISO 6892 work. Expect more maintenance and power demand, but the load headroom prevents mid-test pressure spikes from topping out the system.
Check the rest of the setup before deciding. If clamping forces exceed about 10,000 lbf (45 kN), plan on wedge or hydraulic grips and a frame stiff enough to limit bending. Keep alignment tight, below roughly 0.1 degree, to avoid off-axis loading. Confirm travel and accessory needs, such as chambers from -112 °F to 4000 °F (-80 °C to 2200 °C) and contact or optical extensometers. Many labs pair a 22,000 lbf (100 kN) electromechanical unit with a 110,000 lbf (500 kN) hydraulic unit to cover mixed programs.
You can review electromechanical and hydraulic frames, along with grips and accessories, on the
All Tensile Testing Equipment equipment page.
How Do I Decide Between Electromechanical And Hydraulic UTMs For My Lab?
Start with peak force and strain-rate control. If most work stays below about 22,000 lbf (100 kN), an electromechanical frame gives very stable low-speed control for methods like ASTM D638 or ISO 527. Operators can hold crosshead rates such as 0.02 to 20 in/min (0.5 to 500 mm/min) without hunting, which helps repeat modulus and yield points on plastics, films, and thin metals.
For heavy sections or high-strength alloys per ASTM E8 or ISO 6892, hydraulic machines handle sustained loads above 110,000 lbf (500 kN) and up to 2,000,000 lbf (9 MN). Wedge or hydraulic grips stop slippage on smooth specimens; serrated jaws bite, but switch to smooth or coated faces for soft metals. Align the specimen carefully with centering fixtures so the frame is not fighting bending.
Match accessories to the material. Clip-on extensometers work well for small strains on metals, while optical systems suit large elongations on elastomers. If testing outside ambient conditions, plan for chambers from −112 °F to 4,000 °F (−80 °C to 2,200 °C). Size the load cell so routine tests land near 60 to 80 percent of capacity, and confirm software supports your method library and report format requirements.
If you would like help matching force range, grips, and extensometers, you can review options on the
Tensile Testing Equipment equipment page.
How Do I Choose UTM Type And Capacity For Tensile Testing Of Forged Parts?
Select the frame by matching load range and control needs. Electro-mechanical machines excel at precise crosshead and strain-rate control for low to mid loads, ideal for sub-size coupons and routine alloy checks. Servo-hydraulic machines handle high-capacity work and thick sections, with comfortable headroom near 135 kip (600 kN) or 225 kip (1000 kN). If the expected peak load often exceeds about 60 kip (270 kN), hydraulic usually offers better durability and grip force for large forgings.
Size capacity from a quick calculation: capacity ≥ UTS × area, then add margin for off-axis effects and grip friction. Example: a 0.50 in (12.7 mm) round at 120 ksi (830 MPa) has 0.196 in² (126.5 mm²) area, predicted peak about 23.6 kip (105 kN). With a 30% margin, select at least 31 kip (138 kN). For shafts with localized hardening or variable section, consider a 50% margin.
Match accessories to the standard and geometry. For ASTM E8/E8M, use the specified gauge length, commonly 2.0 in (50 mm), and verify axial alignment per ASTM E1012. Choose wedge or hydraulic grips rated above machine capacity and sized to the grip section. If machining marks remain, apply longitudinal polishing to the gauge to reduce stress raisers before testing.
If you would like to compare frame types, capacities, and accessories, you can review details on the
Tensile Testing Equipment equipment page.
How Should Labs Plan Service and Calibration for Tensile Specimen Preparation and UTM Systems?
Plan annual force verification for UTMs to ASTM E4 or ISO 7500-1, with a maximum interval of 18 months. Reverify after relocation, repairs, or any out-of-tolerance result. In daily use, warm electronics 20 to 30 minutes, check zero, and confirm load-train seating and grip face condition. Log rate control and encoder checks. For alignment, follow ASTM E1012 when required by method or customer, or after grip or fixture changes.
For tensile sample preparation machines, set a practical PM rhythm. Monthly, check spindle runout and toolholders, aiming for ≤ 0.001 in (≤ 0.025 mm). Verify vise or chuck runout and, on lathes, tailstock center height. Cut a verification coupon and confirm critical dimensions to ± 0.001 in (± 0.025 mm) against a calibrated reference.
Budget for consumables and spares that wear, such as end mills, inserts, collets, jaw inserts, and belts. Schedule remote software updates on a set cadence, for example quarterly. Maintain one log that ties calibrations, PM tasks, certificates, and operator training to specific serial numbers. This documentation keeps audits predictable under ISO/IEC 17025, ASTM E4, and ISO 7500-1.
If you would like to review accredited methods and scheduling options, you can read the
Certification for Testing Equipment page to explore details on the information page.
How Should Tensile Tests Be Configured To Qualify Spacecraft Structural Materials?
Start with properly machined coupons that match the governing method for metals, typically ASTM E8 or ISO 6892-1. Use a straight or dog-bone geometry with a 2 in (50 mm) gage length and correct fillet radii, and target a smooth finish around 16 to 32 µin Ra (0.4 to 0.8 µm). For elevated temperature work, apply ASTM E21 procedures. Record the exact blank orientation, heat lot, and machining path so results track back to the flight drawing.
Select a frame and load cell that place expected failure loads in the middle of the range, for example a 50,000 lbf (222 kN) capacity machine for aluminum or titanium coupons. Verify axiality per ASTM E1012 using alignment fixtures, then choose wedge or hydraulic grips with jaw faces matched to thickness to avoid slip or jaw breaks. Control strain rate as required by the method and use an axial extensometer with a 1 or 2 in (25 or 50 mm) gage length for modulus, yield, and elongation.
If mission conditions drive testing beyond ambient, add a chamber that can run from about −320 °F to 1,200 °F (−196 °C to 650 °C). Use thermal shields, high-temperature or cryogenic grips, and specimen temperature verification at the gage section.
If you would like to review suitable frames and accessories for aerospace coupons, you can explore details on the
TM-EML Series D UTM product page.
How Should UTMs Be Configured for Testing Recycled Plastics and Metals?
Start with consistent specimen prep. Sort by resin or alloy lot, remove contamination, and machine coupons to the required standard. Common choices are ASTM D638 Type I for plastics and ASTM E8 subsize for metals, both with 2 in (50 mm) gauge marks. Condition plastics at 73 F and 50 percent RH. A light polish of the reduced section to about 32 µin Ra (0.8 µm) helps control strain localization on brittle blends.
Set the UTM to the method rate. For D638, crosshead speed often falls between 0.2 and 20 in/min (5 to 500 mm/min) depending on modulus. For E8, run the specified strain-rate segment using a clip-on or video extensometer set to 2 in (50 mm). Use wedge or pneumatic grips with faces matched to the material. Align with an alignment fixture, then apply a small preload, for example 10 lbf (45 N), only to remove slack.
Size the frame and load cell so peak load sits near 30 to 80 percent of capacity. If recycled aluminum peaks near 20,000 lbf (89 kN), a 50,000 lbf (222 kN) system provides headroom. The TM-EML Series D covers 11,240 to 224,800 lbf (50 to 1000 kN) with ±0.5 percent accuracy, fitting batches that range from polymers to structural metals.

TM-EML Series D UTM product page.
How Do Labs Simulate Microgravity Tensile Tests On Earth?
For axial data relevant to microgravity, labs focus on removing gravity-related artifacts, not gravity itself. Use low-mass, self-aligning grips and orient thin coupons horizontally to prevent sag. Select a load cell near the expected failure range, for example 10–1,000 lbf (45–4,450 N), and tune servo control for smooth motion at very low speeds.
Thermal and environmental control drive space-relevant testing. Pair the frame with a thermal-vacuum chamber or cryogenic setup to span roughly -320 to 1,650 F (-196 to 900 C). Hold the gauge at uniform temperature, with variation within ±5 F (±3 C), and stabilize the specimen before loading. For lightweight coupons, avoid conductive grip paths that create unintended gradients.
Measure strain with non-contact DIC or a low-mass extensometer rated for the target temperature. Verify load train alignment per ASTM E1012 and force calibration per ASTM E4 or ISO 7500-1. Use self-aligning wedge, collet, or clevis-and-pin grips with spherical seats to reduce bending. Run initial trials at 0.002–0.2 in/min (0.05–5 mm/min) and adjust to maintain the required strain rate window.
For configuration guidance, you can review frame and accessory options on the
All Tensile Testing Equipment page.
When Should a UTM Run in Strain, Displacement, or Load Control?
UTMs can run closed-loop on strain, displacement, or load. Mode selection shapes data quality. For metallic tension per ASTM E8 and ISO 6892-1, use strain control through modulus and yield. Mount a clip-on or non-contact extensometer on a 2 in (50 mm) gauge length. Many labs switch to displacement after uniform elongation to keep the test stable as necking starts.
Displacement control suits plastics and composites where standards specify crosshead rate, such as ASTM D638 or ISO 527. Typical rates range from 0.2 to 20 in/min (5 to 500 mm/min) depending on specimen type. Check grip pressure, jaw condition, and alignment to prevent slip, since crosshead feedback references machine motion rather than true strain.
Load control fits proof loading, seating, and holds. A common routine is ramp to 5,000 lbf (22.2 kN) and hold 60 s. Select a load cell so the expected peak sits near 60 to 80 percent of capacity. TM-EML frames deliver ±0.5 percent of reading when verified to ASTM E4, and alignment checks to ASTM E1012 limit bending. Calibrate speed and strain channels before each lot.
If you would like to compare control features and frame capacities, you can review options on the
All Tensile Testing Equipment page.
How Do UTMs Measure Strain Accurately, And When Should I Use An Extensometer Instead Of Crosshead Displacement?
A UTM reads force through a calibrated load cell, then derives deformation either from an extensometer on the gauge section or from crosshead travel. For modulus, yield offset, and uniform elongation in metals per ASTM E8 or ISO 6892, use a classed extensometer and a defined gauge length such as 2 in (50 mm). Crosshead displacement includes frame and grip compliance, so it skews elastic data and early plastic behavior.
Operators typically run the clip-on or non-contact extensometer through uniform deformation, then remove it before fracture to protect the sensor. As a rule of thumb, if expected strain is 25%, a 2 in (50 mm) gauge length will extend about 0.5 in (12.5 mm); plan removal just before that travel. After removal, continue under position control to break and record force and crosshead displacement while preserving the elastic data already captured by the extensometer.
If the method specifies a strain or extension rate, compute crosshead speed from the target and L0. Example: a 0.05 per minute strain rate on a 2 in (50 mm) gauge translates to 0.10 in/min (2.5 mm/min). Verify the force accuracy class per ASTM E4 or ISO 7500-1 before testing.
If you would like to compare electromechanical frames and extensometer options, you can review details on the
Tensile Testing Equipment equipment page.
How Do I Size And Specify A Dual-Column Electromechanical UTM For Metals Testing?
Start with peak force. Select a frame and primary load cell that keep your expected maximum result near 70 to 80 percent of capacity. For high-strength steels, a dual-column unit covering about 11,000 to 225,000 lbf (50 to 1,000 kN) fits most lab programs. Choose grips rated above your peak by at least 20 percent, for example 15,000 lbf (67 kN) wedges for a 10,000 lbf test. Match jaw faces to the specimen surface to limit slip and bending.
Specify accuracy to the method. ASTM E4 and ISO 7500-1 Class 0.5 are common targets for metals. Plan verification on the test axis with traceable force standards. Pair the load cell with an extensometer that matches your gauge length and strain range, such as 2 in (50 mm) for ASTM E8 or 50 mm for ISO 6892-1. Align the specimen using crosshead guides, then set travel limits before loading.
Check control capability. For method B strain-rate work, you need stable closed-loop control and fine speed resolution down to roughly 0.000002 in/min (0.00005 mm/min). Overload trip near 103 percent protects sensors, and high sampling, for example 1200 Hz, captures yield events without dropouts.

TM-EML Series D UTM product page.
Electromechanical vs Servo-Hydraulic UTMs: How To Choose For Tensile Testing?
Electromechanical frames drive the crosshead with a motor and preloaded ball screws. They deliver stable low-speed control for coupons that require defined rates, with typical motion capability around 0.00004 to 19.7 in/min (0.001 to 500 mm/min). Servo-hydraulic frames use a hydraulic actuator for very high forces and fast response, which suits thick metallic sections and large fasteners.
Match the platform to the expected loads and control mode. Electromechanical systems commonly cover about 11,200 to 135,000 lbf (50 to 600 kN) and are well suited to speed or strain control on metals and polymers. Hydraulic machines cover 225,000 lbf (1000 kN) and up to 450,000 lbf (2000 kN) for heavy sections. Size the load cell so typical failures occur between 10 and 90 percent of capacity. For metals testing under ASTM E8 or ISO 6892, precise speed or strain-rate control is critical.
Consider day-to-day behavior in the lab. Operators running low-force work benefit from quieter operation and minimal oil maintenance on electromechanical frames. High-force steel programs often pair hydraulic frames with wedge grips to reduce slippage. Verify force accuracy per ASTM E4 or ISO 7500-1, check alignment before critical runs, and select grips that match thickness and surface finish.
If you would like selection guidance, you can explore details on the
All Tensile Testing Equipment equipment page.
How To Choose Between Electromechanical and Servo-Hydraulic UTMs for Tensile Testing
Electromechanical frames provide tight speed and strain control from about 0.00004 to 19.7 in/min (0.001 to 500 mm/min) using motor-driven screws. They suit polymers, elastomers, textiles, and thin metals where ASTM D638 or ISO 6892 limits on rate need to be held closely. Servo-hydraulic machines deliver higher forces with generous test space and are chosen for thick sections and high-strength alloys.
As a quick rule, below roughly 22 kip (100 kN) most labs pick electromechanical. From 22 to 225 kip (100 to 1000 kN), either platform can fit, so weigh rate control needs, duty cycle, and facility utilities. At 225 kip (1000 kN) and above, hydraulic frames are typically preferred.
Size the frame with headroom. If your highest break is near 60 kip (267 kN), a 100 kip (445 kN) frame avoids overload trips and leaves room for fixtures. Consider grip style, stroke, and extensometer clearance. For metals, reference ASTM E8 and ISO 6892. For alignment-sensitive programs, add an alignment fixture and verify per ASTM E1012 to reduce bending error.
If you would like to compare frames and specifications, you can review models on the
Tensile Testing Equipment equipment page.
Electromechanical vs Hydraulic UTM: Which Is Right For Metals Tensile Testing?
Match the frame to the peak load and the control method you need. Electromechanical systems give tight speed or strain control for ASTM E8 work, quiet operation, and simple upkeep. They comfortably cover many metals programs up to about 135,000 lbf (600 kN), with crosshead speed ranges that typically reach 20 in/min (500 mm/min). Many accept sub load cells for plastics or elastomers on the same frame, and achieve Class 0.5 accuracy per ISO 7500-1.
Choose a hydraulic unit when specimens demand very high force, such as heavy bar, rebar, or large fasteners. Typical frames span 225,000 lbf (1000 kN) and higher, with displacement rates around 0.02 to 2.8 in/min (0.5 to 70 mm/min). Dual testing spaces and hydraulic wedge grips help maintain clamping at elevated loads, and tensile spaces near 33.5 in (850 mm) accommodate longer specimens.
Practical sizing steps: estimate the maximum break load, then select a load cell or frame at roughly 110% of that value. For example, a 40,000 lbf (178 kN) program pairs well with a 50,000 lbf (222 kN) capacity. Specify grips for thickness and surface, and verify alignment per ASTM E1012 to minimize bending for accurate modulus and yield data.
If you would like a quick comparison of frame types and capacities, you can review details on the
Tensile Testing Equipment equipment page.
How Do I Choose Between Electro-Mechanical And Servo-Hydraulic UTMs For Tensile Testing?
Start with peak force and duty cycle. For work that stays below about 135,000 lbf (600 kN), electro-mechanical frames such as the TM-EML family provide precise low-speed control, quiet operation, and fine positioning for ASTM E8 or ISO 6892 tensile methods. Class 0.5 verification under ASTM E4 or ISO 7500-1 is common, and operators can hold stable rates during yield and uniform elongation segments.
If your program frequently reaches 135,000 to 450,000 lbf (600 to 2,000 kN), servo-hydraulic systems handle high force with steady control across long pulls. Hydraulic wedge grips maintain clamping on thick or surface-treated specimens, which reduces jaw slip and off-axis loading. Many frames offer two test spaces, so tensile runs occur in the upper zone while compression or bend fixtures stay set below.
Plan for infrastructure and tooling. Electro-mechanical machines typically need only electrical service. Servo-hydraulic equipment adds a power unit, fluid care, and heat management. Inventory the correct grips, extensometer range, and strain-control capability for your standard, then schedule periodic calibration to keep force and extension traceable.
If you want to compare frames by force range and control type, you can review options on the
All Tensile Testing Equipment equipment page.
How Do I Choose Between Electromechanical And Servo Hydraulic UTMs For Tensile Testing?
Start by calculating peak force, cross-sectional area times expected UTS, then add a safety margin of 20 to 30% to keep the break within the load cell’s working range. For calibration and traceability, select a frame and load cell that meet ASTM E4 or ISO 7500-1 Class 1 or 0.5.
Electromechanical frames work well for static tensile work where crosshead speed and position control matter, such as ASTM E8 metals and ASTM D638 plastics. Typical speed capability reaches about 19.7 in/min (500 mm/min). The electromechanical range from TensileMill covers roughly 11,200 to 135,000 lbf (50 to 600 kN), fitting most coupon testing, sheet, bar, and medium fasteners.
Choose servo hydraulic when the calculated force approaches heavy sections, rebar, or structural fasteners. Available capacities include about 134,900 lbf (600 kN), 224,800 lbf (1000 kN), and 449,600 lbf (2000 kN). Hydraulic wedge grips and dual test spaces help keep long or thick specimens stable, and large grip windows accommodate round diameters around 0.51 to 2.36 in (13 to 60 mm) and flats up to about 1.57 in (40 mm). For high-accuracy strain work, add an extensometer matched to the gauge length and standard, such as ASTM E8 or ISO 6892.
