Specifies methods for determining the environmental stress cracking (ESC) of plastics when they are subjected to a constant tensile force in the presence of chemical agents. Applies to test specimens prepared by moulding and/or machining and can be used for the determination of ESC of different plastics materials exposed to a specific environment, and for the assessment of ESC of plastics materials exposed to different environments. Coverage includes apparatus, procedure and precision. Also includes diagrams. BS AMD 9927 RENUMBERS STANDARD
