(Specification)Standard Specification for Mechanical Couplings Used on Polyethylene Conduit, Duct and Innerduct
Standard Specification for Mechanical Couplings Used on Polyethylene Conduit, Duct and Innerduct
ABSTRACT
This specification establishes requirements for the qualification of mechanical couplings of particular range of sizes that connect to particular types of polyethylene conduit, duct and innerduct. The couplings covered by this specification are typically designed to join between conduit ends (in-line coupling). The same coupling-to-conduit joint design may be used as a part of other coupling joint designs that telescope, or connect to bulkheads, or other adapter fitting designs. The requirements of this standard apply only to the coupling-to-conduit joint design. The performance requirements of other coupling joint designs are not a part of this standard. The couplings shall conform to the specified pressure and tensile strength requirements.
SCOPE
1.1 This specification establishes requirements for material, performance, workmanship and test methods for the qualification of 2 in. and smaller mechanical couplings that connect to SDR 13.5, DR 15.5, Schedule 40 and Schedule 80 polyethylene conduit, duct and innerduct covered by Specification F2160. Throughout this standard, “conduit” refers to “conduit, duct or innerduct” manufactured in accordance with Specification F2160.
Note 1: F2176 fittings are not applicable to True-sized and ID-controlled conduit per F2160.
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 couplings covered by this specification are typically designed to join between conduit ends (in-line coupling). The same coupling-to-conduit joint design may be used as a part of other coupling joint designs that telescope, or connect to bulkheads, or other adapter fitting designs. The requirements of this standard apply only to the coupling-to-conduit joint design. The performance requirements of other coupling joint designs are not a part of this standard.
1.4 The following safety hazards caveat pertains only to the test methods portion, Section 9 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.
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
