BS ISO 34-1:2004

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

Test methods for the determination of tear strength of vulcanized and thermoplastic rubber.

This International Standard, a part of the BS ISO 34 series, specifies three test methods for the determination of the tear strength of vulcanized and thermoplastic rubber, namely:

- 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 rubber.

This International Standard supersedes BS 903-A3:1995 which is withdrawn.

This International Standard includes the following cross references:

ISO 471:1995, ISO 3383:1985, ISO 4648:1991, ISO 5893:2002, ISO 6133:1998, ISO/TR 9272:1986.
