标准摘要
[中文适用范围]： 本文件规定了用于测定硫化橡胶的温升和抗疲劳性的恒应力屈曲试验。 许多橡胶产品，例如轮胎和皮带，都是通过承受具有恒定峰值应力幅度的振荡负载来进行测试的。 为了获得这些产品的加速测试和使用中暴露之间的良好相关性，本文件给出了在此类条件下进行测量的说明。 该方法不适用于硬度大于 85 IRHD 的橡胶。 [外文原描述]： This document specifies a constant-stress flexometer test for the determination of the temperature rise and resistance to fatigue of vulcanized rubbers. Many rubber products, such as tyres and belts, are tested by subjecting them to an oscillating load with a constant peak stress amplitude. In order to obtain good correlation between accelerated tests and in-service exposure of these products, this document gives instructions for carrying out measurements under such conditions. This method is not applicable for rubber having a hardness greater than 85 IRHD.
