Frequently Asked Questions
A fabric textile tensile tester is a machine. It measures the strength and stretchiness of fabrics. It works by gripping a strip of cloth or other materials, such as leather, paper, or yarn, on both ends. Then, you pull it until it breaks. Advanced sensors measure the force needed to remove the fabric. They also measure how far it stretches before breaking. This gives quantitative data on the fabric’s tensile properties.
The most common testing machine used for tensile testing is the universal testing machine(UTM). It features two crossheads: one is adjusted to accommodate the length of the specimen, while the other is driven to apply tension to the test specimen. These testing machines can be either electromechanical or hydraulic.
For accurate testing, the machine must have appropriate capabilities for the test specimen, including sufficient force capacity, speed, precision, and accuracy. Various accessories, such as grips, extensometers, and temperature chambers, are used to adapt the machine for different materials and testing conditions.
The SmartPull Fabric Textile Tensile Tester software is easy to use. It presents detailed tensile test results. These include elongation, time, greatest force, and modulus. They also include breaking force and more. It allows you to compare past results. You can also export data and create custom reports.
The SmartPull Fabric Textile Tensile Tester weighs 90 kilograms. This is due to its optimized design. So, it’s easier to move and use. It uses the latest technology. This includes AC servo motors and precision ball screws. They make force accuracy better. Its improved hardware and software make the testing 20% more reliable.
It has an emergency stop button and an overload protection system. It also has travel range limits and warns about abnormal torque or issues. Its ergonomic design reduces injury risks.
Before use our tensile testing equipment, check the installation guide for environmental needs and machine securing. Connect electricals according to source rating specifications. Initialize when empty and tare the tester. Next, calibrate in ascending and descending order. Use deadweights certified for 20% to 100% of the capacity range. Save calibration results for further use.
Some entities use standards. They include ISO 13934-1 for strength. ISO 9073 is for fabrics. ISO 4674 is for coated fabrics. There are also ASTM standards. These include D5034 for woven textiles. Additionally, D5587 is for narrow elastic fabrics, and D6797 is for tearing resistance. The choice depends on the material type and test parameters needed. SmartPull applies to over 20 testing standards. This includes the ones mentioned above.
elect matching international test standards based on fabric type. Set suitable grips, jaws, or fixtures. Input the recommended test speed, pre-tension rate, and gauge length as per standard. Specify the allowed elongation percentage without damage. Check if the data recording rate meets the standard. Zero the balance force sensor. Verify the alignment and centering of loaded fabric samples. Start the auto-return on the sample break.
Use pneumatic grips with rubber coating to hold dense, woven fabrics. Use smooth, lightweight mechanical clamps for light, sheer fabrics to avoid damage. Inspect across the width to check the center while loading. Observe the tensioning display to check for slackness or issues. Start a pre-tension cycle to correct minor orientation deviations.
If you see variability, recheck the grip pressure settings. Also, replace worn-out jaws. Recalibrate the load cell if accuracy declines beyond the permissible limit. Confirm that you have pre-conditioned the specimen. Verify that mounted gauge length dimensions are accurate. Increase the sample size or test repeats for more statistical confidence. Compare against certified reference equipment. The room temperature and humidity were stable throughout the entire test duration.
It should cover regular inspections, Including the cleaning and lubricating components. Follow the check cycles to maximize the machine’s lifespan. Clean standard testers, grips, and accessories daily or weekly. Use calibrated torque instruments for couplings and drives. Test oil samples to check for contamination. Inspect belts, pulleys, and couplings for wear using alignment gauges per schedule.
People replace consumable parts. These parts include grips, jaws, load cell mounts, couplings, pulleys, and drive belts. They wear out over time. Calibrated spare sensors and load cells can cut potential downtime. Other recommended spares are fuses, cords, and pneumatic component kits. Their typical replacement frequency varies. The frequency of use determines their usage.

A tensile tester measures tensile strength and elongation. It is also called a universal testing machine (UTM). The test principle involves pulling a specimen until it fails. This allows measurement of its mechanical properties. Here is an overview. It covers the key ideas and parts in a tensile test.
Key Principles
Specimen Preparation:
We prepare a standardized test specimen. Its shape and size can vary based on the material and the standards being followed (e.g., ASTM, ISO).
Clamping:
The specimen is securely clamped between two grips or fixtures. One grip is usually stationary, while the other is attached to a movable crosshead.
Application of Force:
A uniaxial tensile force is gradually applied to the specimen by the crosshead. You can control the application rate. Test standards often set the rate.
Measurement:
During the test, we measure several parameters.
Force Load: The amount of force that someone applies to the specimen.
Extension (Displacement): The change in length of the specimen as it’s stretched.
Measurements are captured through load cells and extensometers in each case.
Data Acquisition:
The test records load and displacement data. This data makes a stress-strain curve. This curve is crucial for analyzing material properties.
Key Components
Load Frame:
The main structure that supports the grips, crosshead, and other components. It is designed to withstand the forces generated during testing.
Crosshead:
It is driven by a servo motor or hydraulic system. It applies the tensile force to the specimen.
Grips/Fixtures:
Devices used to hold the specimen in place. They must be strong enough to prevent slipping or damage to the specimen during testing.
Load Cell:
A sensor that measures the force applied to the specimen. The system reads an electrical signal that converts the mechanical force.
Extensometer:
An instrument used to measure the change in length (extension) of the specimen. It provides data necessary to calculate strain.
Control and Data Acquisition System:
The software and hardware control the test parameters. They capture data from the load cell and extensometer. They also generate the stress-strain curve.
Stress-Strain Curve
The results of a tensile test show a stress-strain curve. It gives key information about how a material behaves under tensile loads, including:
Material deforms reversibly in elastic region, returning to original shape.
The Yield Point is when the material starts to deform plastically. This deformation is irreversible.
Ultimate Tensile Strength (UTS): The largest stress the material can withstand before failure.
Fracture Point: The point at which the material ultimately fails and breaks apart.
Elongation at Break is the total strain the material experiences when it fails.
The SmartPull Tensile Tester can perform tension, compression, bending, tearing, shearing, peeling, and top-breaking tests. Here we introduce 2 types of tension tests. The process follows standardized test methods to ensure consistency and accuracy.
Standardized Test Methods
Common standards for fabric tensile testing include:
- ASTM D5034: Standard Test Method for Breaking Strength and Elongation of Textile Fabrics (Grab Test).
- ASTM D5035: Standard Test Method for Breaking Force and Elongation of Textile Fabrics (Strip Method).
- ISO 13934-1: Textiles – Tensile Properties of Fabrics – Part 1: Determination of Maximum Force and Elongation at Maximum Force Using the Strip Method.
- ISO 13934-2: Textiles – Tensile Properties of Fabrics – Part 2: Determination of Maximum Force Using the Grab Method.
Test Method Overview
Specimen Preparation:
Strip Method: Cut specimens to a specified length and width, usually with a length that is several times the width.
Grab Method: Cut specimens with wider dimensions, but the gripping is done at a narrower central section.
Conditioning:
Precondition the specimens in a controlled environment (typically 21°C ± 1°C and 65% ± 2% relative humidity) for a specified period (often 24 hours).
Mounting the Specimen:
Strip Method: Clamp the entire width of the specimen in the grips.
Grab Method: Clamp only the central section of the specimen, leaving the edges free.
Setting Up the Tensile Tester:
Ensure the tensile tester is calibrated according to the manufacturer’s instructions and relevant standards.
Set the gauge length (the initial distance between the grips) as specified by the test standard.
Applying the Force:
Start the test by applying a tensile force at a specified constant rate of extension (CRE) or constant rate of load (CRL) until the specimen breaks.
Recording Data:
Measure and record the breaking force (maximum force the specimen withstands before breaking) and the elongation at break (the increase in length before failure).
Calculating Results:
Compute the tensile strength by dividing the breaking force by the cross-sectional area of the specimen (for the strip method).
For fabrics, the force is often reported as force per unit width (e.g., Newtons per centimeter).
Reporting Results:
Report the tensile strength and elongation values, and if necessary, provide the mean and standard deviation if multiple specimens were tested.
Detailed Steps for ASTM D5034 (Grab Test)
Specimen Dimensions:
Cut specimens typically 100 mm wide by 150 mm long.
Gripping:
Clamp the specimen in the grips such that the 25 mm from each edge is free, and the central 50 mm is gripped.
Gauge Length:
Set the initial gauge length to 75 mm.
Test Speed:
Apply force at a rate of 300 mm/min.

Calibrating a fabric tensile tester is essential. It ensures accurate and reliable test results. Calibrating the tensile tester involves checking and adjusting its parts. These include the load cell, extensometer, and grips. Here’s a step-by-step guide on how to calibrate a fabric tensile tester:
Step-by-Step Guide to Calibrating a Fabric Tensile Tester
Preparation
Read the ChiuVention SmartPull Tensile Tester’s Manual. Get to know the tensile tester’s user manual and its calibration procedures.
Gather calibration tools. You need certified weights. You also need a standard gauge block or displacement device. You also need calibration software, if needed.
Inspect the tester.
Inspect visually. Look for any damage or wear on the grips, load cell, extensometer, and other parts.
Clean the Universal Tensile Machine
Ensure all parts, especially the grips and the load cell, are clean and free from debris.
Calibrate the load cell.
Warm-Up: Turn on the tensile tester and let it warm up for at least 15 to 30 minutes to stabilize the electronics.
Zero the Load Cell. With no load, set its reading to zero using the universal tensile machine’s controls or software.
Apply Calibration Weights
Attach certified calibration weights to the load cell incrementally.
Record Readings
Note the readings displayed by the tester for each weight.
Adjust the calibration if the readings don’t match the known weights.
Follow the SmartPull’s instructions. Use them to adjust the settings. Do this until the readings match the weights within acceptable tolerance.
Calibrate the extensometer.
Zero the extensometer. Make sure it reads zero when it’s resting (zero displacement) position.
Use a standard gauge block. Place a gauge block or a known displacement device between the extensometer arms.
Check the readings. Verify the displacement matches the gauge block’s known value.
Adjust Calibration: Adjust the extensometer settings if there is a discrepancy. Do this until the readings are accurate.
Calibrate the crosshead speed.
Set a standard speed. Program the tensile tester to move the crosshead at a set speed. For example, 100 millimeters per minute.
Measure the speed. Use a stopwatch and ruler. Measure the actual speed of the crosshead’s movement over a set distance.
Check and change. Compare the measured speed to the programmed speed. Change the universal tensile machine settings if needed.
Software Calibration
Calibration Software: follow the on-screen instructions. They’re for calibrating the load cell, extensometer, and crosshead speed.
Update the firmware. Make sure the tester’s firmware is up to date. Updates may improve calibration.
Verification
Test with standard samples. Run tests on them. They have known tensile properties. This will verify the accuracy of the calibration.
Compare Results: Compare the results with the known values. If there are significant discrepancies, recheck the calibration steps.
Documentation
Record Calibration Data. Document the calibration process. This includes the weights used, readings, adjustments, and verification results.
Create a calibration schedule. Keep to a schedule that’s recommended by ChiuVention or industry standards.
Need to clean up after each test. Keep the equipment clean.
After using the fixture, coat it with anti-rust oil for storage.
Replace the sensor or plug and unplug the cable after turning off the power. If the sensor’s connection is suspended, static electricity can easily damage the amplifier. It can also harm the AD circuit.
The instrument needs to calibrate the load cell often. This ensures the accuracy of the measured value.
Apply lubricant to moving parts at consistent intervals.
If the instrument fails, professionals or the manufacturer should repair it. You must replace spare parts according to the original model.
