DIN EN ISO 22088-5-2009 塑料.耐环境应力开裂(ESC)能力的测定.第5部分:恒定拉伸变形法(ISO 22088-5:2006),ISO 2208-5:2009的德文版本
Plastics - Determination of resistance to environmental stress cracking (ESC) - Part 5: Constant tensile deformation method (ISO 22088-5:2006); English version of DIN EN ISO 22088-5:2009-10
This part of ISO 22088 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.
NOTE 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.
