This specification establishes the requirements for billets made from stress-rated high-density polyethylene (HDPE) materials and intended for fabrication into pipe fittings such as flange adapters and reducers. The billets are manufactured by application of molten extruded material onto a rotating mandrel to form a monolithic mass. The standard includes thermoplastic pipe material designation codes for selection of appropriate stress-rated material, as well as performance requirements for billets and test methods for determining conformance with the requirements. It prescribes minimum quality control measures for manufacturers. Requirements for items fabricated from the billets are beyond the scope of this specification, which covers materials, requirements, test method, certification, product marking, and quality assurance.
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.
Significance and Use
1.1 This specification covers billets made from stress-rated high-density polyethylene (HDPE) materials.
1.2 The billets are manufactured by application of molten extruded material onto a rotating mandrel to form a monolithic mass. Machining prior to dimensioning is acceptable.
1.3 The billets are intended for fabrication into pipe fittings such as flange adapters and reducers.
1.4 Requirements for and use of the fabricated pipe fittings shall be in accordance with an applicable product specification. This specification for billets does not include requirements for items fabricated from the billets.
1.5 This specification includes thermoplastic pipe material designation codes for selection of appropriate stress-rated material, together with performance requirements for billets and test methods for determining conformance with the requirements.
1.6 Minimum quality control measures are prescribed for manufacturers. See Annex A1 for quality control for billets conforming to this specification.
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.8 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.
