ASTM F2767-18

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2767 − 12 F2767 − 18 An American National Standard
Standard Specification for
Electrofusion Type Polyamide-12 Fittings for Outside
Diameter Controlled Polyamide-12 Pipe and Tubing for Gas
1
Distribution
This standard is issued under the fixed designation F2767; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification covers polyamide- 12 electrofusion fittings for use with outside diameter-controlled polyamide- 12 pipe,
covered by Specification F2785. Requirements for materials, workmanship, and testing performance are included. Where
applicable in this specification “pipe” shall mean “pipe” or “tubing.”
1.2 Polyamide 12 electrofusion fittings are intended for use in polyamide 12 systems only. As per the manufacturer’s
recommendations, no cross fusion between PA12, PA11 and PE is permitted.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.4 The following safety hazards caveat pertains only to the test method 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 safety, health, and healthenvironmental practices and determine the applicability of
regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
