中文名称：硫化橡胶或热塑性橡胶 撕裂强度的测定 第1部分：裤形、直角形和新月形试样

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

发布日期：2022-06

标准范围

This document specifies three test methods for the determination of the tear strength of vulcanized or thermoplastic rubber, namely the following:
— 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 can also be susceptible to grain effects in rubber.
NOTE A separate method for the determination of the tear strength of small test pieces of rubber (Delft test pieces) is specified in ISO 34-2.
