Black polyethylene compounds for wire and cable
1 Scope
This standard specifies the product classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of black polyethylene compounds for wire and cable (hereinafter referred to as “polyethylene compounds for cable”).
This standard is applicable to the polyethylene compounds for cable mainly made from polyethylene resin with additives such as carbon black and antioxygen through mixing, plasticizing and granulating.
