PLASTICS - DETERMINATION OF RESISTANCE TO ENVIRONMENTAL STRESS CRACKING (ESC) - PART 2: CONSTANT TENSILE LOAD METHOD (ISO 22088-2:2006, IDT)
This Malaysian Standard specifies methods for the determination of environmental stress cracking (ESC) of thermoplastics when they are subjected to a constant tensile load in the presence of chemical agents.
It is applicable to test specimens prepared by moulding and/or machining and can be used both for the assessment of ESC of plastic materials exposed to different environments, and for the determination of ESC 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: Methods for the determination of environmental stress cracking by means of a constant-strain test are specified in ISO 22088-3, ISO 22088-4 and ISO 22088-5.
