Annotation of standard text ASTM D4976-12a(2020) :

This specification provides the standard requirements for polyethylene plastic molding and extrusion materials. The tests involved in this specification are intended to provide information for identifying materials in accordance with the groups, classes, and grades covered. Polyethylene plastic materials are classified into two groups in accordance with the molecular structure which may be branched or linear. Test specimens shall be compression molded, conditioned in a standard or controlled laboratory atmosphere, and tested to determine the materials´ physical and electrical properties. The specimens shall comply with the following requirements: flow rate; density; tensile stress at yield; nominal strain at break; secant flexural modulus; environmental stress-crack resistance; slow crack growth resistance; thermal stress crack resistance; permittivity; dissipation factor; volume resistivity; water immersion stability; flammability; and weatherability.
