ASTM International Standard Specification for Polyethylene Plastics Pipe and Fittings Materials ASTM D3350-21

This specification covers the identification of polyethylene plastic pipe and fitting materials. Cell classification of materials shall be according to tests of primary properties like density, melt index, flexural modulus, tensile strength at yield, slow crack growth resistance, and hydrostatic strength classification. Materials shall be manufactured by molding and extrusion of polyethylene plastic in the form of powder, granules, or pellets. Color and ultraviolet stabilizer, thermal stability, brittleness temperature, density, tensile strength at yield, and elongation at break shall conform to this specification.
