This standard specifies a method for determining the environment stress cracking (ESC) performance of a plastic specimen in a specific environment by applying ball or needle pressure on it. Suitable for molded and machined plastic products. Tests include drilling holes, inserting steel balls or needles, and testing in a chemical medium. Evaluation of cracking by visual observation or determination of tensile, bending performance. The standard describes in detail sample preparation, test operation steps, and representation of results to assess the cracking resistance of plastics under specific environment conditions.
