标准范围

ISO 22088-4:2006规定了一种通过恒定应变试验测定塑料环境应力开裂（ESC）性能的球或销压痕法。该方法适用于成品和通过模塑和/或机加工制备的试样，可用于评估暴露在不同环境中的塑料产品或材料的ESC行为，以及确定暴露在特定环境中的不同塑料材料的ESC行为。ISO 22088-3和ISO 22088-5规定了通过恒定应变试验确定环境应力开裂的替代方法。ISO 22088-2规定了通过恒定应力试验确定环境应力开裂的方法。

ISO 22088-4:2006 specifies a ball or pin impression method for the determination of the environmental stress cracking (ESC) behaviour of plastics by means of a constant-strain test.The method is applicable to finished products and to test specimens prepared by moulding and/or machining, and can be used for the assessment of the ESC behaviour of a plastic product or material exposed to different environments, as well as for the determination of the ESC behaviour of different plastics materials exposed to a specific environment.An alternative method for the determination of environmental stress cracking by means of a constant-strain test is specified in ISO 22088-3 and ISO 22088-5. A method for the determination of environmental stress cracking by means of a constant-stress test is specified in ISO 22088-2.
