标准摘要
[中文适用范围]： ISO 22088 的这一部分规定了一种测定热塑性塑料在化学介质存在下承受恒定拉伸变形时的环境应力开裂 (ESC) 行为的方法。 它适用于通过成型和/或机械加工制备的测试样品，可用于评估塑料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。 环境。 这本质上是一个排名测试，并不旨在提供用于设计或性能预测的数据。 注：ISO 22088-3 和 ISO 22088-4 中规定了通过恒应变试验确定环境应力开裂的替代方法。 ISO 22088-2 中规定了通过恒定拉伸载荷测定环境应力开裂的方法。 [外文原描述]： ISO 22088-5:2006 specifies a method for the determination of the environmental stress cracking (ESC) behaviour of thermoplastics when they are subjected to a constant tensile deformation in the presence of a chemical medium. It is applicable to test specimens prepared by moulding and/or machining and can be used for the assessment of the ESC behaviour of plastic materials exposed to different environments, as well as for the determination of the ESC behaviour 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. Alternative methods for the determination of environmental stress cracking by means of a constant-strain test are specified in ISO 22088-3 and ISO 22088-4. A method for the determination of environmental stress cracking by means of a constant tensile load is specified in ISO 22088-2.
