Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes requ
3、irements for fabri-cated fittings intended for use with outside-diameter controlledpolyethylene pipe and tubing. These fittings are manufacturedby heat-fusion joining shape-modified polyethylene compo-nents prepared from pipe, molded fittings, sheet, or block.Included are requirements for materials,
4、 design, workmanship,minimum dimensions, marking, test methods, and qualitycontrol.1.2 Pressure rating of the fabricated-fitting design is beyondthe scope of this standard and shall be established by the fittingmanufacturer. This specification includes requirements for bothroom temperature and eleva
5、ted temperature pressure-tests todemonstrate a reasonable level of performance of thefabricated-fitting design at the pressure rating established bythe fitting manufacturer.1.3 The pressure-tests requirements are specified by DR.The DR specified is that of the piping system for which thefabricated f
6、itting is intended to be butt-fused.1.4 The text of this standard references notes and footnoteswhich provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be consideredas requirements of the standard.1.5 UnitsThe values stated in inch-pound units a
7、re to beregarded as standard. The values given in parentheses aremathematical conversions to SI units which are provided forinformation only and are not considered standard.1.6 The following safety hazards caveat pertains only to thetest methods portion, Section 9, of this specification. Thisstandar
8、d does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.
