Description

This specification establishes requirements for dimensions and gaging of taper pipe threads used on threaded plastic pipe and fittings.

Scope

Threads meeting this specification shall only be used on those plastic materials deemed suitable by the manufacturer.

Specialty threads or threads not requiring a leak-tight joint are not covered in this specification.

Note 1: The terms “wrench makeup” and “wrench tight” are standard terminology for tightness and do not imply using a pipe wrench or other tools which would damage plastic pipe and fittings. The terms “hand-tight” and “hand-tight engagement” refer only to thread gaging (not pipe and fitting connections) and is the definition of the L1 gage length.

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 limitations prior to use. For specific precautionary statements, see 7.2.1 and 8.3.
