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 DR 15.5 and lower polyethylene conduit, duct and innerduct covered by Specification F 2160
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 and health practices and determine the applicability of regulatory requirements prior to use.
