标准摘要
[中文适用范围]： ISO 22088 的这一部分描述了通过以恒定速率缓慢增加施加到拉伸样品的应变来评估化学环境中聚合材料的环境应力开裂 (ESC) 敏感性的程序。 它适用于通过模压和/或机械加工制备的测试样品，可用于评估暴露于不同环境的材料的相对ESC敏感性或暴露于特定环境的不同塑料的相对ESC敏感性。 这本质上是一个排名测试，并不旨在提供设计数据。 与 ISO 22088 第 2 至 5 部分中描述的测试方法相比，该测试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。 [外文原描述]： 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.
