2、of revision, the year of last revision. 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 fabricated fittings intended for use with ou
3、tside-diameter controlledpolyethylene pipe and tubing. These fittings are manufactured by heat-fusion joining shape-modified polyethylene componentsprepared from pipe, molded fittings, sheet, billet, or block. Included are requirements for materials, design, workmanship,minimum dimensions, marking,
4、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 fittingmanufacturer. This specification includes requirements for both elevated temperature pressure-tests and short-term pressurizationtests to
5、 demonstrate a reasonable level of performance of the fabricated-fitting design at the pressure rating established by thefitting manufacturer.1.3 This specification includes requirements for both elevated temperature pressure-tests at the pressure rating established bythe fitting manufacturer.1.4 Th
6、e pressure-tests requirements are specified by the fittingsequivalent (E) DR. The EDR specified is the DR of the pipingsystem for which the fabricated fitting is intended to be butt-fused.1.5 The text of this standard references notes and footnotes which provide explanatory material. These notes and
7、 footnotes(excluding those in tables and figures) shall not be considered as requirements of the standard.1.6 UnitsThe values stated in inch-pound units are to be regarded as standard. The values given in parentheses aremathematical conversions to SI units which are provided for information only and
8、 are not considered standard.1.7 The following safety hazards caveat pertains only to the test methods portion, Section 9, of this specification.specificationThis standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of theuser of
9、this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardizationestablished i
