superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This specification covers requirements for non-pressure polyolefin pipe and fittings for drainage, waste, and vent applications.
NOTE 1—This specification does not include requirements for pipe and fittings intended to be used to vent combustion gases.
1.2 Pipe is produced in Schedule 40 and 80 IPS sizes, in metric sizes, and in DR IPS sizes for two polyolefins; polyethylene (PE)
and polypropylene (PP).
1.3 The interchangeability of pipe and fittings made by different manufacturers is not addressed in this specification.
1.4 Pipe and fittings are joined by the heat fusion method (Practice D2657 for PP butt and saddle fusion, Practice F2620 for PE
butt, saddle and socket fusion and Practice F1290 for polyolefin electrofusion) or by using mechanical or gasketed joints
recommended by the pipe and fitting manufacturers.
1.5 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.
1.6 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.
1.7 The following safety hazards caveat pertains only to the test methods portion, Section 8, 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, health, and environmental practices and determine the applicability of regulatory
limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
