标准摘要
[中文适用范围]： 1.1 ISO 22088的本部分规定了通过恒定应变试验测定塑料的环境应力开裂（ESC）性能的球或销压印方法。1.2 本方法适用于成品以及通过模压和/或机械加工制备的试样的测试，可用于评估塑料制品或材料暴露于不同环境下的ESC行为，以及测定不同塑料材料暴露于特定环境下的 ESC 行为。1.3 球压印法和销压印法是评估塑料 ESC 行为的快速且灵敏的方法 [外文原描述]： ISO 22088-4:2006 specifies a ball or pin impression method for the determination of the environmental stress cracking (ESC) behaviour of plastics by means of a constant-strain test. The method is applicable to finished products and to test specimens prepared by moulding and/or machining, and can be used for the assessment of the ESC behaviour of a plastic product or material exposed to different environments, as well as for the determination of the ESC behaviour of different plastics materials exposed to a specific environment. An alternative method for the determination of environmental stress cracking by means of a constant-strain test is specified in ISO 22088-3 and ISO 22088-5. A method for the determination of environmental stress cracking by means of a constant-stress test is specified in ISO 22088-2.
