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.

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.
