标准摘要
[中文适用范围]： 本文件规定了用于评估硫化橡胶或热塑性橡胶在静态或动态拉伸应变下暴露于含有一定浓度臭氧的空气、一定温度和（如果需要）一定相对湿度且无直射光影响的空气中时抗开裂性的程序。使用目视观察或图像分析（或两者兼有）来评估裂纹的形成和扩展。还可以确定暴露导致的物理或化学性质的变化。ISO 1431-3 中描述了确定臭氧浓度的参考方法和替代方法。 [外文原描述]： This document specifies the procedures intended for use in estimating the resistance of vulcanized or thermoplastic rubbers to cracking when exposed, under static or dynamic tensile strain, to air containing a definite concentration of ozone, at a definite temperature and, if required, at a definite relative humidity in circumstances that exclude the effects of direct light. Either visual observation or image analysis, or both, are used to evaluate the formation and growth of cracks. The changes in physical or chemical properties resulting from exposure can also be determined. Reference and alternative methods for determining the ozone concentration are described in ISO 1431-3.
