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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers the identification of polyethylene plastic pipe and fittings materials in accordance with a cell classification system. It is not the function of this specification to provide specific engineering data for design purposes, to specify manufacturing tolerances, or to determine suitability for use for a specific application.
1.2 Polyethylene plastic materials, being thermoplastic, are reprocessable and recyclable (Note 2). This specification allows for the use of those polyethylene materials, provided that all specific requirements of this specification are met.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
