  • Description
  • Literature

This standard mainly applies to most woven textile fabrics, but can be applicable to fabrics produced by other techniques. The method specifies a procedure to determine the tear strength of textile fabrics using the double tear tongue method. A rectangular specimen is cut in multiple places to form a tongue, which is used to propagate two tears and determine the tear strength.

For this test, it is important to have an increased test data rate to ensure the capture a high number of data points. This is because when individual fibers within the fabric fail, the data rate must be fast enough to catch these peaks.

Pneumatic side action grips with rubber coated jaw faces are well suited for clamping of the trouser specimens. While manual action grips will work, many prefer pneumatic side action grips for ease of use, productivity, and better repeatability. Adjustable grip pressure also allows users to fine-tune the gripping pressure to avoid jaw breaks or slippage.

The challenges of testing to this standard are:

  • Rapid data capture rate
  • Specimen gripping

Instron's Solution:

  • Rapid data capture rate with Instron's 5900 controller allows data peaks and valleys to be captured accurately at up to 2,500 points per second
  • Instron pneumatic side action grips with rubber faces are well-suited to gripping nearly all types of fabric specimens for this test while maintaining high throughput

It is important to review ISO 13937-4:2000 in order to fully understand the test setup, procedure, and results requirements.
