GB/T 43316.1-2023

This standard provides general guidance for determining the resistance of plastic materials to environmental stress cracking (ESC), a failure mechanism where cracking occurs under tensile stress in the presence of specific chemicals or environments. It is applied in the rubber and plastics industry for material selection, quality control, and product development, particularly for components like pipes, containers, and automotive parts that may contact aggressive media. The guidance establishes testing principles and conditions, serving as a foundational reference for subsequent parts of the standard that detail specific test methods.
