scope:

This International Standard specifies three test methods for the determination of the tear strength of vulcanized rubber, namely: - Method A, based on the use of a trouser test piece; - Method B, based on the use of an angle test piece, with or without a nick of specified depth; - Method C, based on the use of a crescent test piece. 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.
