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
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.
