What is included in the test method d5035?

 

This test is designed to measure the maximum force necessary to break a textile fabric and the amount a fabric will stretch or elongate under that force before it breaks, providing indications of the fabric's strength and stretchability.

 

Essentially, the procedure includes the following steps:

 

1. Sample Preparation: A strip of fabric of a specific size and shape is cut from the fabric to be tested. The exact dimensions usually depend on the type of fabric and the purpose of the test.

 

2. Mounting: The fabric strip is clamped into the jaws of a tensile testing machine, ensuring the machine grips the strip securely without distorting the fabric.

 

3. Testing: The tensile testing machine then pulls apart the fabric strip at a controlled rate until the strip breaks. The highest force applied when the fabric breaks is noted.

 

4. Elongation Measurement: The amount the fabric stretched before it broke, known as the elongation, is also recorded.

 

5. Result Calculation: The breaking force and elongation are typically reported in terms of force per unit width and percentage of original length, respectively.

 

6. Reporting: The results gleaned from the test are then reported, often consisting of the average and range of breaking force and elongation values, and possibly the coefficient of variation if enough samples have been tested.

 

This testing method is applicable to most woven textile fabrics, including cloth made from glass fibers and air bag fabric, and can also be used, with caution, for fabrics produced by both nonwoven and knit methods.
