Test Method: SATRA TM30

Tear strength - trouser leg method

April 2017


This method is intended to determine the force required to tear a material. The method is mainly applicable to non-leather footwear upper and lining materials, but can be used with all types of thin flexible material.


A test specimen, which has a single slit to produce two legs, is loaded into a tensile testing machine so that the slit is parallel to the axis of the machine and one leg is clamped in each jaw, see figure 1. The jaws are moved apart to tear the material until the tear has propagated to an edge of the test specimen. The average force required to propagate the tear, the type of tear and the thickness of the test specimen are recorded.
