BS EN ISO 22088-5:2009 Plastics. Determination of resistance to environmental stress cracking (ESC). Constant tensile deformation method
BS EN ISO 22088-5 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 applies 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 BS EN ISO 22088-3 and BS EN ISO 22088-4. A method for the determination of environmental stress cracking by means of a constant tensile load is specified in BS EN ISO 22088-2.
