Universal Testing System
5 kN / 50 kN

The C-Series is available in several force capacities: 1124 lbf, 2248 lbf, 4496 lbf, 5618 lbf, 6744 lbf, and 11,240 lbf (5 kN, 10 kN, 20 kN, 25 kN, 30 kN, and 50 kN). Each configuration maintains Class 0.5 accuracy across its operating range and supports both static and cyclic test modes.
Selecting the proper rating depends on the expected failure load of your specimen. A capacity where peak forces fall within roughly 10–70 percent of the load-cell range provides optimal precision and stability. Higher-capacity models are recommended when working with metallic coupons, composite laminates, reinforced plastics, or specimens requiring long-travel fixtures or dual-space configurations.

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

The C-Series dual-column UTM uses a high-stiffness frame with twin guide rails, preloaded ball screws, and a reinforced crosshead. This geometry distributes load along both columns, reducing bending and lateral deflection under higher forces. The result is more stable alignment for modulus, yield, and tensile strength measurements, especially on metallic and composite specimens or when using long-travel fixtures.
Compared with single-column or low-capacity TM-EML models, the C-Class structure is optimized for loads up to 50 kN and frequent cyclic work. It maintains alignment over a larger test space and under heavier fixtures, which is important for high-precision strain measurement, dual-space configurations, and applications where even small frame deflections would affect results.

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.

The TM-EML Series C UTM works with the GenTest software platform, which includes a built-in library of preconfigured ASTM, ISO, EN, and GB/T methods for tensile, compression, flexural, and cyclic testing. Each method template stores crosshead control mode, speed or strain rate, preload routine, break criteria, result items, and reporting layout. Operators can load a standard template, adjust sample dimensions, and start testing without redefining the procedure every time.
For more advanced workflows, GenTest allows users to copy an existing standard method and save it as a custom template with lab-specific names, acceptance limits, or additional result calculations. Methods can be grouped by material type, department, or standard family so that production, QA, and R&D teams see only the procedures relevant to their work. Access levels can also be configured so that supervisors manage templates while day-to-day operators simply select the correct method from a controlled list.

See our standards and certification.

The TM-EML C-Series includes real-time force monitoring and adaptive PID feedback that control the initial preload with high precision. This prevents sudden force spikes when gripping thin films, brittle composites, or high-strength metallic coupons. The system also uses closed-loop position and force limits to avoid unintended loading during alignment or jogging.
Additional protection is provided through collision detection, 103% overload cutoff, and dual limit switches that stop movement instantly if unsafe conditions occur. When paired with pneumatic grips, the digital pressure-control module adds controlled clamping force to reduce slippage and prevent damage during test initiation.

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.

The TM-EML C-Class dual-column frame has the same footprint in all layouts, approximately 30.3 × 25.2 in (770 × 640 mm). The overall height depends on configuration. A standard single-space unit is about 66.9 in high (1700 mm), while extended versions reach up to 90.6–92.9 in (2300–2360 mm). These taller configurations are typically used as floor-standing systems or mounted on a dedicated workbench.
Working height is defined by vertical crosshead travel. Standard single-space systems offer about 39.4 in of travel (1000 mm). Extended frames increase travel up to 63.0 in (1600 mm), which is useful for long specimens or tall fixtures. Frame weight is roughly 816 lbs (370 kg) for a single-space layout and about 926 lbs (420 kg) for dual-space models, giving the C-Class UTM the rigidity needed for mid- to high-force testing.

See our standards and certification.

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.

The TM-EML Series C supports a wide range of extensometers for elastic modulus, yield, and high-elongation measurements. Standard clip-on extensometers are recommended for metals, plastics, and composites that require high accuracy within a controlled gauge length. These devices provide stable, low-noise strain readings with resolution suitable for modulus determination.
For long-elongation materials such as elastomers, foams, and highly ductile polymers, non-contact video extensometers or long-travel sensor arms are available. These options allow measurement over large displacements without removing the sensor during the test. High-temperature extensometers with ceramic arms are also supported for chambers operating up to elevated thermal ranges, ensuring reliable strain capture during heated tensile, creep, or relaxation procedures.

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
• System alignment and functional testing
• 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.

The TM-EML C-Configuration supports a wide crosshead speed range suitable for both slow strain-rate precision work and high-speed production testing. Standard models reach up to about 900 mm/min, while high-speed return can reach approximately 1500 mm/min. Ultra-slow motion is also supported, down to roughly 0.00005 mm/min, allowing controlled creep, relaxation, and low-strain-rate studies.
Strain-rate control remains stable across the entire range due to the closed-loop digital servo system operating at 1200 Hz. This enables accurate, repeatable strain-rate loading for metals, composites, polymers, and long-elongation samples without drift or speed–position errors.

See our standards and certification.

On the TM-EML Series C universal testing machine, most routine changes such as swapping grips, fixtures, or standard load cells are designed to take only a few minutes when handled by a trained operator. Grips and fixtures mount on standardized adapters, so changeover is usually limited to loosening the mechanical fasteners, removing the current accessory, installing the new one, and confirming alignment in GenTest. Load cells use a quick mechanical interface with auto-recognition, so once the sensor is mounted and the connector is attached, the system reads its calibration data without manual re-entry.
For dual-space frames, switching between upper and lower test spaces is also straightforward. Operators typically reposition the crosshead to the required space, verify limit positions, and select the corresponding method in the software. When planning frequent reconfiguration, many labs keep commonly used fixtures and load cells preinstalled in each test space, which reduces downtime and keeps the C-Series frame ready for both tensile and compression work with minimal adjustment.

See our standards and certification.

Yes. The TM-EML C-Class UTM supports integration with a wide range of external sensors and environmental devices through its multi-channel controller and synchronized data acquisition architecture. The system accepts inputs from extensometers, strain gauges, displacement sensors, temperature probes, and custom analog devices through six high-resolution channels. Each channel is sampled at 1200 Hz, allowing all auxiliary signals to remain fully synchronized with force and position data.
Environmental chambers, heating units, cooling systems, and high-temperature extensometers may also be connected through GenTest. The accessory management module automatically detects compatible devices and assigns the correct channel configuration, helping operators maintain reliable alignment between mechanical and temperature-dependent measurements. Custom R&D accessories can be added using the system’s analog and digital input ports when a specialized workflow requires unique instrumentation.

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

Yes. The C-Class UTM supports ultra-low strain-rate and micro-displacement control through its high-resolution servo system, which delivers stable motion from 0.00005 mm/min upward. The closed-loop controller processes force, position, and strain feedback at 1200 Hz, allowing precise control during creep, relaxation, and long-duration load-hold sequences.
The system’s extended low-speed performance, high-resolution encoder, and adaptive PID logic provide the consistency required for materials that show slow deformation, time-dependent behavior, or highly sensitive displacement responses. These tests can be run through standard GenTest modules or saved as custom multi-stage sequences for research applications.

See our standards and certification.

Yes. The TM-EML C-Class UTM can be equipped with an integrated industrial touchscreen PC mounted directly to the load frame. This configuration enables fully stand-alone operation without the need for a separate workstation.
A touchscreen setup provides access to GenTest™ software, live graphing, test method libraries, and reporting functions directly from the mounted terminal. However, users may also operate the machine through a traditional external PC when required, both options function interchangeably.

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

Yes. The C-Series frame can run cyclic, staged, and waveform-based loading programs through the advanced sequencing tools built into GenTest. The controller supports tension–compression cycling, incremental loading, load-hold segments, and custom ramps with high precision thanks to its 1200 Hz closed-loop feedback and adaptive control logic.
Operators can build multi-stage profiles with variable speed, force, strain, or displacement targets, allowing the machine to evaluate fatigue behavior, stress–relaxation tendencies, and time-dependent deformation. Waveform control options include sine, triangle, trapezoid, and user-defined shapes, each running at stable amplitudes and frequencies suitable for mid- to high-force materials. These sequences can be saved as reusable templates for research, production, or accreditation workflows.

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.

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.

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.

The pneumatic grip control module on the TM-EML C-Class UTM provides digital pressure regulation for upper and lower grips, allowing operators to set precise clamping force from the control console or directly through GenTest. Pressure is adjusted through an integrated electronic regulator, and quick-connect fittings allow fast grip installation for tensile or compression fixtures that require air operation.
The module improves workflow by automating clamping force, reducing operator variability, and preventing over-tightening that could damage delicate or compliant specimens. It also speeds up repetitive testing, since operators can store pressure presets and switch between materials without recalibration. The safety logic keeps grip movement disabled until the test space is clear and the system is in a safe state.

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, a dedicated safety enclosure is available for the dual-column TM-EML C-Series UTM. The enclosure uses a reinforced aluminum frame with polycarbonate panels and includes a door-interlock system that disables crosshead motion when the door is open.
It is recommended for high-force metallic specimens, brittle composites that may fragment on failure, cyclic loading at extended durations, and any laboratory workflows requiring controlled operator access around moving components. Facilities performing repetitive production testing or working under strict safety protocols typically adopt the enclosure as a standard requirement.

See our standards and certification.

On the TM-EML C-Class UTM, usable test space is defined by vertical crosshead travel and the clear width between columns. The clear test width is about 16.5 in (420 mm) across all configurations, which sets the maximum specimen and fixture width that can be mounted between the columns.
Vertical crosshead travel depends on the selected frame height. Typical values include:
Standard single-space frame: about 39.4 in travel (1000 mm)
Standard dual-space frame: about 35.4 in travel (900 mm) in the main test space
Extended 300 mm single-space: about 51.2 in travel (1300 mm)
Extended 600 mm single-space: about 63.0 in travel (1600 mm)
Effective test height in practice is the crosshead travel minus the length of grips, fixtures, and any extensometers or chambers installed in the test area. This configuration range allows the C-Series system to handle short standard coupons as well as longer assemblies or high-elongation specimens.

See our standards and certification.

The TM-EML Series C UTM provides micro-displacement control with a position resolution of 0.0000004 in (0.01 µm). Speed accuracy is within ±0.2% of the set speed across the full operating range, from ultra-low creep and relaxation speeds up to high crosshead travel rates used for productivity-focused testing.
Force measurement uses high-resolution load cells with a resolution of 1/600000 of full scale. The system meets Class 0.5 accuracy from 0.2–100% of rated load in the 500 N–50 kN range (and 0.4–100% in the 10–250 N range), with verification based on GB/T 16825.1, ISO 7500, and ASTM E4. A closed-loop frequency and data sampling rate of 1200 Hz support stable force, displacement, and strain control during both static and cyclic tests.

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.

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.

The TM-EML Series C Universal Testing Machine is a dual-column electromechanical system designed for mid- to high-force tensile, compression, flexural, and cyclic testing. Its servo-driven direct-drive system, FEM-optimized frame, and high-stiffness structure allow the machine to maintain stable load control and accurate alignment during demanding test programs.
The C-Series is used for determining modulus, yield strength, tensile strength, deformation behavior, and other mechanical properties in routine QC environments, engineering laboratories, and research facilities. It is suitable for metals, reinforced polymers, composites, rubbers, foams, and applications requiring higher load capacity and precise strain measurement.

See our standards and certification.

The TM-EML C-Series supports a full range of load cells from 500 N up to 50 kN (11240 lbf). Each sensor is factory-calibrated to Class 0.5 accuracy and uses TEDS auto-recognition, allowing the controller to detect and configure the load cell as soon as it is mounted. This eliminates manual setup and minimizes calibration errors.
Multiple load cells can be interchanged on the same C-Series frame. Operators can switch between low-capacity sensors for sensitive materials and high-capacity cells for structural samples. Built-in overload logic, side-force protection, and bidirectional design (tension/compression) increase sensor durability and reduce the risk of drift or premature failure during repeated changes.

See our standards and certification.
