标准范围

ISO 22088-6:2006描述了通过以恒定速率缓慢增加施加在拉伸试样上的应变来评估化学环境中聚合物材料的环境应力开裂（ESC）敏感性的程序。它适用于通过模塑和/或机加工制备的试样，可用于评估暴露于不同环境中的材料的相对ESC敏感性，或暴露于特定环境中的不同塑料的相对ESC敏感性。这本质上是一种排名测试，不用于提供设计数据。与ISO 22088第2部分至第5部分中所述的试验方法相比，该试验的主要优点是可以快速评估特定聚合物/环境组合的ESC敏感性。

ISO 22088-6:2006 describes a procedure for assessing the environmental stress cracking (ESC) susceptibility of polymeric materials in chemical environments by slowly increasing the strain applied to a tensile specimen at a constant rate.It is applicable to test specimens prepared by moulding and/or machining and can be used to assess the relative ESC susceptibility of a material exposed to different environments or the relative ESC susceptibility of different plastics exposed to a specific environment.This is essentially a ranking test and is not intended for the provision of design data.The principle advantage of the test compared with the test methods described in Parts 2 to 5 of ISO 22088 is the rapidity with which the ESC susceptibility of a particular polymer/environment combination can be assessed.
