Abstract
This specification covers polyethylene socket-type fittings for use with outside diameter-controlled polyethylene pipe and tubing. Fittings covered by this specification are normally molded. In-line fittings such as couplings, unions, bushings, caps, nipples, etc., may be extruded or machined from extruded stock. Special fittings such as transition fittings and tapping teets shall be assembled and fabricated. Conditioning, dimensions, short-term rupture test, and sustained pressure test shall be performed to conform with the requirements specified.
Scope
1.1 This specification covers polyethylene socket-type fittings for use with outside diameter-controlled polyethylene pipe as specified by Specifications D3035 and D2513. Requirements for materials, workmanship, dimensions, and pressure performance are included. Where applicable in this specification, “ pipe” shall mean “pipe and tubing.”
1.2 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.
1.3 The following safety hazards caveat pertains only to the test method 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.
1.4 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.
