Rubber, vulcanized or thermoplastic — Determination of tear strength — Part 1: Trouser, angle and crescent test pieces

Specifies three test methods for the determination of the tear strength of vulcanized rubber: method A, using a trouser test piece; method B, using an angle test piece, with or without a nick of specified depth; method C, using a crescent test piece with a nick. The value of tear strength obtained depends on the shape of the test piece, speed of stretching and temperature of test. It may also be susceptible to grain effects in vulcanized rubber.
