Test Method: SATRA TM213

Tear strength - Elmendorf method

October 2003

SCOPE

This SATRA test method is intended to determine the tearing strength of woven fabrics when subjected to a dynamic load. The method is intended for woven fabrics only and is not suited to fabrics that are knitted.

PRINCIPLE

A conditioned test specimen, adjusted to an accurate dimension by fraying down is placed into the jaws of a tear tester. One of the jaws holding the test specimen is static and the other jaw is attached to a pendulum. The apparatus is capable of applying different tearing forces to a test specimen depending on the attachment of different loads to the pendulum. A small knife cut is made in the test specimen, which serves as a point from which to propagate tearing. The pendulum is released and the test specimen is torn. The force required to tear the test specimen is read from the tear tester.
