Standards:

SATRA TM103:2018 Resistance of elastics to repeated extension

Applications:

Elastic Tape Fatigue Testing Machine is used to determine its repeatedly extend performance under maximum extension for elastic fabric and elastic band, also can be used to determine fatigue resistance of extensible material.

Product Information:

This instrument is used to test the elasticity of elastic belt after reciprocating movement.

Features

Drive the elastomer sample to repeatedly elongate until it reaches effective growth limit. Regularly evaluate the damage and stop test when it reaches test times or damage exceeded a predetermined level.

Test Procedures

1. Sample Pre-treatment

Cut a sample to fit the 170mm test clamp width and place it in a standard environment (23±2℃, relative humidity 50±2%, or 20±2℃, relative humidity 65±2%) for 24 hours.

2. Equipment Preparation

Connect to a 220V 50Hz AC power supply, check the overall status of the instrument, clear the test station, and ensure the equipment is free of any abnormalities.

3. Parameter Setting

Set the parameters through the instrument panel – the maximum stroke should not exceed 150mm, and the test speed should be adjusted to (65±5) cpm. Then, set the target number of cycles using the six-digit LCD counter (e.g., 10000 cycles).

4. Sample Installation

Securely clamp the pre-treated sample onto the test clamp, ensuring that the sample is subjected to even force and is not loose or skewed.

5. Start Testing

After confirming that the parameter settings and sample installation are correct, start the instrument to begin the reciprocating tensile test.

6. Process Monitoring

Regularly observe the sample status during the test and record any abnormalities such as damage or breakage.

7. Test Termination

The test automatically stops when the instrument reaches the preset number of cycles, or the test is manually terminated if the sample damage exceeds the standard (e.g., breakage rate > 10%).

8. Result Recording

Record the actual number of cycles using the LCD counter, and also record in detail any damage or breakage of the sample.

FAQ

1. What is an Elastic Tape Fatigue Testing Machine?

The Elastic Tape Fatigue Testing Machine is a device designed to evaluate the durability and performance of elastic materials, such as elastic tapes, bands, or straps, under repeated stretching and relaxing cycles.

2. How does the machine perform fatigue testing?

The machine repeatedly stretches and releases the elastic tape under controlled tension and speed. This simulates long-term usage and helps assess how the tape’s elasticity, strength, and shape retention change over time.

3. What types of elastic materials can be tested?

The machine is suitable for a variety of elastic materials, including woven elastic bands, knitted elastics, medical tapes, sports bands, and other stretchable textiles. It can accommodate different widths and thicknesses.

4. What parameters can be measured during testing?

The machine measures parameters such as elongation, recovery, tensile strength, breaking point, and fatigue life (number of cycles until failure or significant deformation). Some models also provide real-time data logging and graphing.

5. Why is elastic tape fatigue testing important?

Fatigue testing ensures that elastic products maintain their performance, elasticity, and reliability under repeated use. It helps manufacturers improve product quality, extend lifespan, and reduce failures in real-world applications.
