标准摘要
[中文适用范围]: 本文件规定了测定硫化橡胶或热塑性橡胶撕裂强度的三种试验方法,即: ——方法 A,使用裤形试件; ——方法B,使用角度试件,有或没有规定深度的缺口; ——方法 C,使用带有缺口的新月形试件。 获得的撕裂强度值取决于测试件的形状、拉伸速度和测试温度。 它还容易受到橡胶中颗粒效应的影响。 注:ISO 34-2 中规定了测定橡胶小试件(代尔夫特试件)撕裂强度的单独方法。 [外文原描述]: 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.
