Application Summary AI generated

This standard specifies test methods for evaluating the resistance to environmental stress cracking, melt flow index, and carbon black or mineral filler content in polyethylene and polypropylene compounds used as insulating and sheathing materials. It is applied in the manufacturing and quality control of electric and optical cables to ensure the durability and performance of polymer-based cable jackets under mechanical and environmental stress. The standard is particularly relevant for cable producers and testing laboratories assessing material consistency and long-term reliability in outdoor or underground installations.
