1 Scope
This standard specifies the classification and designation, requirements, test methods, and inspection rules of polyethylene (PE) resin as well as marking, packaging, transportation and storage of its products.
This standard is applicable to ethylene homopolymers or copolymer of ethylene and other 1-olefins as monomers and polymers containing additives.
This standard is not applicable to ultra-high molecular weight polyethylene and colored, filled, modified and reinforced polyethylene resin and masterbatch materials.
