标准摘要
[中文适用范围]： ISO 22088的本部分规定了热塑性塑料在化学试剂存在下承受恒定拉伸载荷时的环境应力（ESC）的测定方法。 它适用于通过模压和/或机械加工制备的测试样品，并且可以既可用于评估暴露在不同环境下的塑料材料的ESC，也可用于测定暴露在特定环境下的不同塑料材料的ESC。 这本质上是一个排名测试，并不旨在提供用于设计或设计的数据。 性能预测。 [外文原描述]： ISO 22088-2:2006 specifies methods for the determination of environmental stress cracking (ESC) of thermoplastics when they are subjected to a constant tensile load in the presence of chemical agents. It is applicable to test specimens prepared by moulding and/or machining and can be used both for the assessment of ESC of plastic materials exposed to different environments, and for the determination of ESC of different plastic materials exposed to a specific environment. This is essentially a ranking test and is not intended to provide data to be used for design or performance prediction. Methods for the determination of environmental stress cracking by means of a constant-strain test are specified in ISO 22088-3, ISO 22088-4 and ISO 22088-5.
