2、. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification establishes requirements for fabri-cated fittings intended for use with outside-diameter controlledpolyethylene
3、 pipe and tubing. These fittings are manufacturedby heat-fusion joining shape-modified polyethylene compo-nents prepared from pipe, molded fittings, sheet, billet, orblock. Included are requirements for materials, design,workmanship, minimum dimensions, marking, test methods,and quality control.1.2
4、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 bothelevated temperature pressure-tests and short-term pressuriza-tion tests to demonstrate a reasonable level of per
5、formance ofthe fabricated-fitting design at the pressure rating establishedby the fitting manufacturer.1.3 The pressure-tests requirements are specified by thefittingsequivalent (E) DR. The EDR specified is the DR of thepiping system for which the fabricated fitting is intended to bebutt-fused.1.4 T
6、he 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 are to beregarded as standard. The values
7、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. Thisstandard does not purport to address all of the
8、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.
