For high-force tensile and compression tests, the Series D is compatible with clip-on extensometers, strain-gauge extensometers, and long-travel units designed for large-strain materials. Standard clip-on devices are suitable for metals, alloys, and rigid composites, while high-temperature extensometers can be used when chambers or elevated heating is required.
For advanced research or non-contact strain measurement, video extensometers and optical strain systems can be integrated through the available analog and digital input channels. These solutions support precise strain tracking during high-load and high-stiffness applications.

See our standards and certification.

Yes. The TM-EML Series load frames from TensileMill CNC are built to be precise, steady, and reliable, meeting key international standards for tensile and compression testing.
These include, for example:
ASTM E4 – Verification of force measurement accuracy
ISO 7500-1 – Verification of static uniaxial testing machines
ASTM E8 / ISO 6892 – Tension testing of metals
ASTM E83 / ISO 9513 – Verification of extensometers
ASTM E1012 – Alignment verification for tension/compression testing systems
When required, TensileMill CNC can coordinate third-party or lab-accredited calibration through ISO/IEC 17025-compliant partners.
Compliance expectations and documentation requirements vary depending on the testing environment (e.g., production QC, R&D lab, accredited laboratory).
If your facility operates under a specific certification framework, we can provide the required alignment fixtures, verification documentation, and calibration support based on your application.

See our standards and certification.

GenTest for the D-Class UTM includes a preloaded library of methods organized by standard (ASTM, ISO, EN, GB/T) and test type, such as metallic tensile, compression, bend, and high-temperature tests. Each method contains predefined control modes, calculations, and result items appropriate for high-force work, including modulus, yield, tensile strength, elongation, and reduction of area.
Operators can duplicate these base methods, adjust specimen dimensions, limits, or control parameters, and save them as custom templates for specific materials or product families. This approach keeps standardized procedures consistent while still allowing tailored configurations for different Series D applications.

See our standards and certification.

The D-Class dual-column floor-standing structure uses reinforced guidance columns, preloaded ball screws, and high-stiffness linear rails that carry load symmetrically on both sides of the crosshead. This reduces bending, side loading, and frame deflection when testing high-strength steels, large cross-section specimens, or fixtures with substantial mass. Frame stiffness rises from about 270 kN/mm in the 50–100 kN range up to 1300 kN/mm in the 1000 kN model, which supports precise modulus and yield measurements even at very high loads.
Because the TM-EML Series D frame is optimized using finite element analysis and designed with zero-clearance mechanical interfaces, alignment remains stable over years of operation.

See our standards and certification.

TM-EML systems support standard alignment procedures required for NADCAP and similar audit programs. The machines can be verified using alignment fixtures that are compatible with ASTM E1012 and ISO alignment practices. These fixtures help measure load-string symmetry, bending strain, and overall force distribution so the operator can adjust grips, adapters, and crosshead position before certification.

GenTest software also assists with controlled loading steps during alignment checks, which simplifies interaction with accredited calibration providers. If you need guidance on preparing a TM-EML system for an upcoming audit or want to confirm the correct alignment fixture for your frame, you can contact us or request support.

Lower-capacity TM-EML systems operate on standard single-phase power. Series A runs on 220 V ±10 %, 50/60 Hz, with a typical load of roughly 600 W. Series B and benchtop Series C also use single-phase 220 V and draw about 1–1.5 kW depending on the installed motor and accessories.

High-capacity Series D machines require a three-phase 220 V ±10 %, 50/60 Hz connection. Their power rating varies by frame size, generally from 2 kW up to 11 kW. These units should be connected to a properly protected circuit sized according to local electrical rules.

If you are unsure whether your facility can support a specific configuration, you can contact us and we will help verify the requirements before installation.

For help or support, talk to a specialist.

Benchtop TM-EML models only need a stable, non-vibrating workbench that can reliably support their weight. For example, the Series A frame requires about 22.8 × 20.4 in (580 × 520 mm) of bench space and weighs around 238 lb (108 kg).

Series B frames are larger at roughly 30 × 25 in (770 × 640 mm) and about 595 lb (270 kg). A small clearance zone behind the machine, usually 6–8 in (150–200 mm), is helpful for cable routing and routine access.

Keeping the sides open makes it easier to change grips and fixtures. Floor-standing Series C and D machines need a level concrete surface and enough vertical clearance for full crosshead travel.

Larger Series D frames can reach 2,200–13,000 lb (1000–6000 kg), so a reinforced floor is generally preferred. If you are planning a first-time installation or moving a unit to another room, you can contact us so we can review the layout with you.

For help or support, talk to a specialist.

A standard TM-EML system includes the load frame, AC servo controller, precision load cell matched to the selected capacity, and the GenTest software package. Basic grips or compression platens are typically supplied according to the test methods specified in the order.

Each frame also includes safety controls such as emergency-stop, limit switches, and motor protection features. Common upgrades include pneumatic grips, additional load cells for wider test ranges, long-travel or high-resolution extensometers, environmental chambers, and protective safety enclosures.

Many users also add custom fixtures or a larger touchscreen PC when they need a more integrated workstation. If you want help selecting optional components for your application, you can contact us.

See our standards and certification.

Yes. TensileMill CNC provides installation, operator training, and calibration for all TM-EML Series universal testing machines, either at delivery or as scheduled verification.

Typical calibration and setup support includes:

• Verification of load cell and force-measurement accuracy
• Validation of extensometers and displacement systems

• Operator instruction for daily use and test setup
• Calibration documentation traceable to ASTM and ISO requirements

Annual calibration is generally recommended for labs operating under ISO 9001 or ISO/IEC 17025. To schedule service, talk to our team.

Yes. The Series D platform is compatible with high-temperature extensometers designed for use inside environmental or furnace chambers. These extensometers maintain accuracy at elevated temperatures and allow measurement of modulus, yield, and elongation when metals, alloys, or composites are tested under heat.
The frame architecture and controller support stable strain tracking during thermal expansion, slow strain-rate work, and long-duration high-temperature cycles, making the system suitable for elevated-temperature tensile and creep testing.

For help matching this to your lab, talk to a specialist.

Yes. TM-EML Series D systems support IEEE 1451.4 TEDS auto-recognition. Each compatible load cell carries embedded calibration and configuration data that the controller reads automatically when the sensor is installed. This removes the need for manual parameter entry and reduces the chance of configuration errors.
TEDS support also speeds up load-cell interchange when switching between high-capacity and lower-capacity sensors. The system applies the correct calibration profile and force range as soon as the load cell is connected.

See our standards and certification.

To confirm the warranty term for your configuration or region, talk to a specialist.

Minimum speed across the entire Series D lineup is 0.00005 mm/min, supporting fine strain-rate control, creep studies, and micro-displacement work. Maximum speed varies by model: about 850 mm/min for 50–100 kN systems, 600 mm/min for the 200–300 kN range, 330 mm/min for 500–600 kN systems, and 300 mm/min for the 1000 kN platform.
The return speed is also capacity-dependent, reaching up to 1200 mm/min on lighter models and lower values on heavier frames to keep motion stable at high mass and high stiffness.

For help matching this to your lab, talk to a specialist.

See our standards and certification.

The Series D frame supports integration with high-temperature furnaces, environmental chambers, liquid-bath fixtures, and thermal conditioning units designed for tensile, compression, and creep testing.
External sensors such as clip-on extensometers, high-temperature extensometers, strain gauges, load-monitoring transducers, temperature probes, and video extensometers can be connected through the system’s analog channels and high-speed digital inputs. The machine includes Ethernet and USB communication options, allowing synchronization with third-party DAQ systems and custom R&D accessories.

For help matching this to your lab, talk to a specialist.

The TM-EML Series D controller operates with a closed-loop control frequency of 1200 Hz and a real-time data sampling rate of 1200 Hz. Force, displacement, and extensometer signals are captured and updated at this frequency for all capacity levels.
Along with the 24-bit A/D conversion on multiple analog channels and high-speed digital inputs, this control rate allows the high-force frame to follow detailed load or strain profiles and maintain stable behavior during static, cyclic, or waveform-driven tests.

For help matching this to your lab, talk to a specialist.

Yes. TensileMill CNC keeps a stocked inventory of consumables and replacement parts for the TM-EML Series to support continuous operation and reduce downtime.

Frequently stocked items include:

• Grips and jaw sets (manual, pneumatic, and specialty)
• Extensometer accessories and cable assemblies
• Load cells across capacity ranges
• Bearings, seals, belts, and mechanical wear components
• Control boards and modules compatible with GenTest

Most parts ship preconfigured and plug-and-play, with reorder options for high-wear items. Explore our consumables and spare parts.

Non-contact and video extensometers can be used with the Series D for applications where gripping damage, high elongation, or thermal conditions make clip-on sensors unsuitable. The frame provides stable optical access, and the controller supports synchronized signal acquisition from digital or analog outputs of video-based systems.
These solutions allow tracking of strain without physical attachment to the specimen, which is important for brittle materials, wide-strain polymers, elevated-temperature work, and waveform-controlled loading profiles.

See our standards and certification.

TM-EML systems can exchange data with external platforms through the export functions in GenTest. The software supports common formats such as CSV, Excel, and PDF, which allows laboratories to upload results to LIMS, MES, or internal reporting systems without custom programming.

Many users also integrate raw curves and calculated parameters into third-party analysis tools through automated import routines. For more advanced workflows, custom data exports can be configured in GenTest so that results follow your lab’s naming rules or batch structure.

If you need help setting up an integration or confirming compatibility with your existing platforms, you can contact us or request support.

For help or support, talk to a specialist.

Yes. The Series D UTM supports the full range of advanced profiles through GenTest, including cyclic loading, multi-stage sequences, creep, relaxation, hold ramps, and waveform-driven control (such as sine or trapezoidal patterns).
These sequences can combine force, displacement, strain, or extension control modes, switching between them without interruption during the test. Users can save custom profiles as templates for repeated use in production or research workflows.

See our standards and certification.

The TM-EML load frames themselves do not require compressed air or external ventilation. These utilities are needed only when specific accessories are installed. Pneumatic grips operate from a standard laboratory air supply, typically in the 80–100 psi range (5.5–7 bar).

If your facility does not have compressed air, a small standalone air compressor can be used. Environmental chambers may require their own electrical connection or ventilation pathway depending on the model, but these requirements come from the chamber, not the TM-EML frame.

All core machine functions, including motion control and data acquisition, run solely on the electrical supply listed for each series. If you are planning to add pneumatic grips, a chamber, or another powered accessory, you can contact us so we can confirm the utility requirements for your configuration.

For help or support, talk to a specialist.

Frame stiffness increases proportionally with force capacity. The 50–100 kN group provides stiffness suitable for mid-strength metals and composites. The 200–300 kN group introduces thicker guidance columns and higher resistance to lateral deflection. The 500–600 kN models use reinforced load structures with substantial rigidity for heavy industrial materials. The 1000 kN model offers the highest stiffness level across the series, designed to maintain alignment under extreme loads and during long-duration or cyclic tests.
Higher stiffness improves modulus accuracy, reduces bending effects, and maintains alignment when using large fixtures or high-temperature accessories.

See our standards and certification.

The system minimizes preload shock by combining low-speed jog control, adjustable approach settings, and real-time force monitoring. Operators can position the crosshead gradually and apply only as much initial force as needed to seat the specimen properly. The closed-loop controller tracks force changes at 1200 Hz and stops movement immediately if a sudden increase occurs.
For gripping brittle or high-strength materials, the machine supports pneumatic or mechanical grips with controlled clamping pressure. This allows uniform, repeatable gripping without localized overstress. Specimen-protection logic in the controller ensures that gripping, alignment, and preload steps occur with stable force control before the test sequence begins.

For help matching this to your lab, talk to a specialist.

TM-EML systems use a fully digital closed-loop architecture that continuously reads force, displacement, and motor position to adjust motion in real time. The controller samples data at a high rate, allowing the machine to maintain stable speed, force, or strain during the test, even when the material response changes suddenly.

All models use high-resolution measurement electronics paired with precision load cells and encoders. This gives consistent feedback across the entire TM-EML family, from low-force Series A units up to high-capacity Series D frames.

The data stream is synchronized with GenTest software, so the operator can view live curves, switch control modes smoothly, and record accurate results without delays. If you want to review data acquisition options or confirm compatibility with your workflow, you can contact us or request support.

For help or support, talk to a specialist.

Return speed after a test depends on the capacity group. For 50–100 kN and 200–300 kN models, the maximum return speed is about 1200 mm/min. This helps clear the test space quickly between samples while keeping motion smooth.
For higher-capacity frames, the return speed is reduced to keep heavy moving parts stable. The 500–600 kN systems return at up to roughly 500 mm/min, and the 1000 kN platform at about 400 mm/min. This balance supports reasonable turnaround time without introducing vibration or shock into the frame.

For help matching this to your lab, talk to a specialist.

The servo direct-drive and synchronous belt system replaces conventional gear reducers to achieve smoother motion, reduced vibration, and minimal mechanical backlash. This provides accurate crosshead positioning across the full speed range, from 0.00005 mm/min up to the model’s maximum speed.
The high-rigidity belt transmission also improves acceleration control and stability during fast ramps, waveform testing, and high-load transitions. This design helps maintain consistent strain-rate control and uniform motion even on heavy-capacity frames.

For help matching this to your lab, talk to a specialist.

The TM-EML Series D uses a combination of firmware and mechanical safeguards to protect load cells during high-force operation. Overload protection activates at roughly 103 percent of the rated capacity and immediately stops crosshead motion if the measured load rises above the permissible limit. This prevents force spikes from damaging the sensor during unexpected specimen failure or setup errors.
Mechanical protection is built into the load cell assembly using rigid couplings, centered mounting surfaces, and low-clearance interfaces that help eliminate lateral loading. The structure keeps the force path aligned with the column centerline so that side loads, bending moments, and off-axis stresses do not transfer to the load cell.

See our standards and certification.

Benchtop TM-EML models, such as Series A and Series B, can be moved relatively easily as long as proper lifting support is available. Their size and weight allow safe relocation on a sturdy cart or through a simple two-person lift when space is limited.

Before moving, the crosshead should be secured and all grips, load cells, and fixtures removed. Floor-standing Series C and Series D machines require more planning due to their height and overall weight.

These units should be moved with certified lifting equipment and handled by trained personnel. After relocation, a basic verification of alignment and measurement accuracy is recommended to confirm proper setup in the new environment.

For help or support, talk to a specialist.

The TM-EML Series is designed to be straightforward for both new and experienced users. Control runs through the GenTest software, which provides a structured workflow for setting up and running tensile and compression tests.

Key usability features include:

• Preloaded test-method templates based on common ASTM and ISO procedures
• Step-by-step configuration prompts that reduce setup time and operator error
• Live force and displacement graphing for clear monitoring
• Automatic calculation and report generation after each test
• Multi-language support, depending on configuration

Accessory changes, such as swapping grips or installing an extensometer, are quick and tool-efficient, with calibration parameters retained in software. For new operators, initial training focuses on selecting the method, installing the specimen, running the cycle, and exporting results.

Once the basic workflow is understood, daily testing stays consistent with minimal adjustment. See our standards and certification.

Yes. The Series D supports an optional full protective enclosure built with an aluminum-reinforced frame and impact-resistant polycarbonate panels. It encases the test area to contain debris, specimen failures, or grip releases during high-force testing.
The enclosure uses interlock logic that prevents crosshead movement when the door is open. This is particularly useful when working with high-strength metals, thick composite laminates, or tests that involve brittle specimens under elevated load or temperature conditions.

For help matching this to your lab, talk to a specialist.

The TM-EML Series D universal testing machine is available in both single-space and dual-space layouts. Single-space frames provide one primary test area and are typically used when most work is tensile or compression testing with standard grips and fixtures. Dual-space frames add a second test area, usually above or below the primary space, which allows one station to be optimized for tensile work and the other for compression, bending, or custom fixtures.
For 50–100 kN and 200–300 kN models, standard, +300 mm, and +600 mm extended-height versions are available in both single-space and dual-space designs. The 500–600 kN and 1000 kN platforms also offer standard and extended-height dual-space options so that long specimens, compression platens, or high-temperature chambers can remain installed without frequent reconfiguration.

See our standards and certification.

Each configuration is built around the same control electronics and GenTest platform but differs in mechanical design, stiffness, travel parameters, and test-space dimensions.
50–100 kN models: Standard dual-column layout with higher crosshead travel, fastest movement speeds, and a compact footprint suitable for most laboratory conditions.
200–300 kN models: Reinforced frame, increased stiffness, and shorter test space to support higher load transmission.
500–600 kN models: Heavy-duty structure with thicker columns, extended crosshead guidance, and slower maximum speeds to stabilize high-force loading.
1000 kN model: Maximum stiffness with a large footprint, reinforced couplings, reduced travel speed, and extended dual-space options for long or bulky specimens.

See our standards and certification.

Overall dimensions, working height, and weight for the TM-EML Series D high-force UTM depend on capacity and test-space configuration. All models share a dual-column floor-standing layout with increasing height and mass as capacity rises.
For reference ranges by capacity group:
TM-EML 50–100 and 200–300 models: about 46.3 × 28.0 × 100.4–126.8 in (1175 × 710 × 2550–3220 mm) with crosshead travel from roughly 49.2 to 76.8 in (1250–1950 mm) depending on standard or extended frame. Weight is approximately 2205–3307 lb (1000–1500 kg).
TM-EML 500–600 models: about 56.3 × 33.5 × 108.7–123.6 in (1430 × 850 × 2760–3140 mm) with crosshead travel from about 25.6 to 41.3 in (650–1050 mm). Weight is roughly 6528–7654 lb (2960–3470 kg).
TM-EML 1000 model: about 61.8 × 39.4 × 122.0–139.8 in (1570 × 1000 × 3100–3550 mm) with crosshead travel from about 19.7 to 35.4 in (500–900 mm). Weight is approximately 12,082–13,621 lb (5480–6180 kg).

See our standards and certification.

TM-EML systems include several built-in safeguards for routine tensile, compression, and flexural testing. Each frame is equipped with an emergency-stop button, upper and lower travel limits, motor overload protection, and automatic force shutdown if a specimen fails unexpectedly.

These functions help protect both the operator and the load cell during abnormal loading. Optional protective enclosures are available for applications that involve brittle specimens, sharp fragments, or higher-energy failures.

These enclosures surround the test area with impact-resistant panels and allow the operator to work at a safe distance while still having full access to grips and fixtures. If you need help choosing the correct enclosure for your setup, you can contact us.

Explore our consumables and spare parts.

The TM-EML Series D includes multi-layer safety logic that monitors force, displacement, and motor conditions in real time. Overload protection activates at approximately 103 percent of rated capacity, stopping motion if force rises beyond the safe limit. Collision detection monitors sudden force spikes and halts the crosshead to prevent specimen breakage from damaging the load cell or mechanical components.
Additional systems include mechanical limit switches, programmable stroke limits, sensor-range protection, and a dedicated emergency-stop circuit. Together, these features maintain controlled operation and protect both the operator and the machine during high-load testing.

For help matching this to your lab, talk to a specialist.

Crosshead travel varies by load capacity and frame height. The 50–100 kN and 200–300 kN groups offer approximately 49.2–76.8 in (1250–1950 mm) depending on standard or extended configurations. The 500–600 kN models provide about 25.6–41.3 in (650–1050 mm), while the 1000 kN system ranges from roughly 19.7–35.4 in (500–900 mm).
Extended-height versions add up to 300 mm or 600 mm of additional travel for long specimens, high-temperature chambers, or tall fixtures where extra clearance is required.

See our standards and certification.

TM-EML systems work best in a controlled laboratory environment. The recommended room temperature is roughly 60–77 °F (15–25 °C), kept stable during testing to avoid drift in force or displacement readings.

Relative humidity should stay low to moderate, typically below 70 %, without condensation in the test area. Vibration should be minimal. Benchtop frames perform well on a solid lab bench, while large Series D units benefit from placement on a stable concrete floor.

Strong external vibration, such as from nearby heavy machinery, should be avoided, especially when using high-resolution extensometers or low-force load cells. Altitude is generally not a limiting factor for system performance, but laboratories located significantly above sea level may notice small changes in pneumatic accessory behavior.

For a tailored recommendation, request a personal quote.

The TM-EML Series D is a high-capacity dual-column floor-standing universal testing machine built for demanding tensile, compression, flexural, and cyclic applications. The system supports force ratings from 50 kN up to 1000 kN and is engineered for accurate, stable, and repeatable operation under heavy loads. Its frame stiffness, direct-drive motion system, and high-resolution feedback architecture allow precise control during both static and dynamic testing.
It is used for testing high-strength metals, structural alloys, engineered composites, and other materials that require controlled strain-rate behavior or high-force loading. The machine is suitable for both routine mechanical characterization and advanced R&D workflows.

See our standards and certification.

Usable test width depends on the capacity group. The 50–300 kN models provide a test width of about 23.6 in (600 mm), while the 500–600 kN and 1000 kN units increase this to approximately 29.5–35.0 in (750–890 mm).
This width defines the maximum fixture size or environmental chamber that can be installed between the columns and determines the largest specimen geometry that can be positioned without interference.

For help matching this to your lab, talk to a specialist.

The TM-EML Series D uses a high-resolution optical encoder system with micro-displacement position resolution down to 0.0095 µm, depending on the frame capacity. Typical values are approximately 0.0095 µm for the 50–100 kN models, 0.0067 µm for the 200–300 kN units, and around 0.011 µm for the 500–600 kN and 1000 kN configurations.
This resolution is maintained across the usable speed range of the D-Class UTM and supports precise strain-rate control, small crosshead movements, and accurate positioning during high-force tensile and compression tests.

See our standards and certification.

GenTest on the TM-EML Series D provides real-time graphing with force–displacement, stress–strain, and time-dependent curves displayed at the full 1200 Hz sampling rate. The interface supports zooming, scaling, overlaying multiple curves, and viewing up to 12 active data channels during a test.
For reporting and exports, users can generate automatic summaries that include modulus, yield, tensile strength, elongation, and other standard parameters. Data and graphics can be exported in CSV, Excel, PDF, PNG, and SVG formats, which makes it easy to archive results or process them in external software platforms.

See our standards and certification.

The TM-EML Series D supports very low crosshead speeds down to 0.00005 mm/min, which allows controlled long-duration creep and relaxation tests even on high-strength materials. In combination with the high-resolution encoder (down to 0.0095 µm) and Class 0.5 force accuracy, the system can track slow deformation and force decay with stable feedback.
Strain-rate control can reach approximately 0.00007 s⁻¹ when paired with suitable extensometers or high-temperature setups. Closed-loop control and data acquisition at 1200 Hz help keep force, displacement, and strain signals synchronized, which is important when running extended tests at ultra-low rates.

For help matching this to your lab, talk to a specialist.

The Series D is available in the following force ratings: 50 kN, 100 kN, 200 kN, 300 kN, 500 kN, 600 kN, and 1000 kN. These cover both mid-capacity and ultra-high-capacity material testing requirements. All models use the same control architecture but differ in frame size, stiffness, motor power, and crosshead travel.
The correct capacity depends on the maximum expected load of your specimen and the applicable testing standards. A proper safety margin is required so the highest specimen load falls within the 10–90 percent portion of the machine’s force range.

See our standards and certification.

The D-Class high-force universal testing machine is used across demanding sectors, including:

• Industrial laboratories and quality-control departments
• Aerospace and automotive R&D centers
• Steel and foundry operations
• Advanced manufacturing of composites and high-temperature alloys
• Universities, national laboratories, and certification-driven facilities

Teams deploy this platform for routine lot release, process validation, and materials qualification where high loads and traceable results are required. Typical workflows include metallic tensile per ASTM E8 and ISO 6892-1, elevated-temperature tensile per ASTM E21, and compression per ASTM E9, often with environmental chambers, furnaces, and high-capacity grips.

With available force ranges from 11,240 to 224,810 lbf (50 to 1,000 kN), the system covers plate and bar stock, heavy fasteners, weldments, forgings, castings, and large-section additive builds. Research groups also use it for strain-rate studies and thermal-exposure programs, supported by precise closed-loop control and extensometry.
