1.1 This specification covers requirements and test methods for the qualification of metallic mechanical fittings for use with outside diameter controlled thermoplastic gas distribution pipe and tubing as specified in Specification D2513, F2785, or F2945.

1.2 The test methods described are not intended to be routine quality control tests.

1.3 This specification covers the types of mechanical fittings described in 3.3.

1.4 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.

1.5 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.

1.6 The following safety hazards caveat pertains only to the test method portion, Section 7, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 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.


This specification covers requirements and test methods for the qualification of metallic mechanical fittings for use with outside diameter controlled thermoplastic gas distribution pipe and tubing. Types of mechanical fittings: clamped insert fitting; compression fitting; compression gasket fitting; and stab-type fitting. The following tests shall be performed: tensile strength test; temperature cycling test; constant tensile load joint test; and elevated temperature sustained pressure test.
