1. Scope

1.1 This specification establishes requirements for fabricated fittings intended for use with outside-diameter controlled polyethylene pipe and tubing. These fittings are manufactured by heat-fusion joining shape-modified polyethylene components prepared from pipe, molded fittings, sheet, or block. Included are requirements for materials, design, workmanship, minimum dimensions, marking, test methods, and quality control.

1.2 Pressure rating of the fabricated-fitting design is beyond the scope of this standard and shall be established by the fitting manufacturer. This specification includes requirements for both room temperature and elevated temperature pressure-tests to demonstrate a reasonable level of performance of the fabricated-fitting design at the pressure rating established by the fitting manufacturer.

1.3 The pressure-tests requirements are specified by DR. The DR specified is that of the piping system for which the fabricated fitting is intended to be butt-fused.

1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.5 Units The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.

1.6 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 limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
