This specification covers polyethylene (PE) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water. Polyethylene plastics used to make pipe meeting the requirements of this specification are categorized in two criteria: short-term strength tests and long-term strength tests. The plastics are defined by four hydrostatic design stresses developed on the basis of long-term tests. The material shall conform to the required limits of burst pressure, environmental stress cracking, and sustained pressure.

1.1 This specification covers polyethylene (PE) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see appendix). Included are criteria for classifying PE plastic pipe materials and PE plastic pipe, a system of nomenclature for PE plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, and environmental stress cracking. Methods of marking are also given.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.

1.4 The following safety hazards caveat pertains only to the test methods portion, Section 7, of this specification: 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.
