Overview

ISO 13955:1997/Amd 1:2020 is an important amendment to the international standard covering plastics pipes and fittings, specifically addressing the crushing decohesion test for polyethylene (PE) electrofusion assemblies. Originally published in 1997, this amendment issued in 2020 updates normative references and testing procedures to enhance the reliability and quality assessment of PE electrofusion joints used in fluid transport systems. Developed by ISO/TC 138 and its subcommittee SC 5, this standard focuses on mechanical testing protocols essential for ensuring the structural integrity of electrofusion welded polyethylene pipe joints, which are widely used in water, gas, and chemical distribution networks.
