Application Summary AI generated

This standard specifies a test method for evaluating the resistance of plastics to environmental stress cracking (ESC) using a ball or pin impression technique. It is applied in the rubber and plastics industry to assess how materials withstand cracking when exposed to chemicals or environmental conditions under localized stress, such as in packaging, automotive components, or industrial plastic parts. The method is particularly relevant for quality control and material selection in manufacturing contexts where plastics encounter aggressive media or sustained mechanical loads.
