ISO 1431-1:2022 硫化橡胶或热塑性橡胶 耐臭氧龟裂 第1部分：静态和动态应变试验

标准编号：ISO 1431-1:2022

中文名称：硫化橡胶或热塑性橡胶 耐臭氧龟裂 第1部分：静态和动态应变试验

英文名称：Rubber, vulcanized or thermoplastic — Resistance to ozone cracking — Part 1: Static and dynamic strain testing

发布日期：2022-06

标准范围

本文件规定了用于估算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中，在一定温度下，以及在排除直射光影响的情况下（如需要）在一定相对湿度下时的抗开裂性的程序。目视观察和/或图像分析用于评估裂纹的形成和扩展。也可以确定暴露引起的物理或化学性质的变化。ISO？中描述了测定臭氧浓度的参考方法和替代方法1431-3.

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.Visual observation and/or image analysis 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.
