标准范围

ISO 22088-2:2006规定了热塑性塑料在存在化学试剂的情况下承受恒定拉伸载荷时环境应力开裂（ESC）的测定方法。本标准适用于通过模塑和/或机加工制备的试样，既可用于评估暴露在不同环境中的塑料材料的ESC，也可用于测定暴露在特定环境中的不同塑料材料的ESC。这本质上是一种排名测试，并不打算提供用于设计或性能预测的数据。ISO 22088规定了通过恒定应变试验确定环境应力开裂的方法-ISO 22088-4和ISO 22088-5。

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.
