标准摘要
[中文适用范围]: ISO 22088 的这一部分是测定热塑性塑料在化学试剂存在下承受固定弯曲应变时的耐环境应力开裂 (ESC) 性能的方法。 ESC 通过适当选择的指示性能的变化来表示测试方法适用于测定片状和平板测试样本的电阻,尤其是样本局部表面区域对 ESC 的敏感性。 弯曲条法是适用于测定由气体、液体以及含有迁移物的固体引起的ESC [外文原描述]: ISO 22088-3:2006 specifies a method for the determination of the environmental stress cracking (ESC) resistance of thermoplastics when they are subjected to a fixed flexural strain in the presence of chemical agents. ESC is indicated by the change of a suitably chosen indicative property of specimens that have been strained for a defined time in the environment. The method of test is suitable for determining the resistance of sheets and of flat test specimens, especially the sensitivity of localized surface regions of specimens, to ESC. This is essentially a ranking test and is not intended to provide data to be used for design or performance prediction. For a constant strain test, refer to ISO 22088-5. For a constant load test, refer to ISO 22088-2.
