Test Method: SATRA TM218

Tear strength of rubbers and plastics - trouser method

June 1999

SCOPE

This method is intended to determine the force required to tear a material. The method is applicable to all types of polymeric material and in particular footwear soling materials or suitable material cut from finished soles or shoes.

PRINCIPLE

A test specimen, which has a single slit to produce two legs, see figure 1, 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. The jaws are moved apart to tear the material by extending the slit until the tear has propagated to the end or 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.
