ASTM F1948-99ae1

Standard Specification for Metallic Mechanical Fittings for Use on Outside Diameter Controlled Thermoplastic Gas Distribution Pipe and Tubing

SCOPE
1.1 This specification describes 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 D 2513.
1.2 The test methods described in this specification are not intended to be routine quality control tests.
1.3 This specification covers the types of mechanical fittings described in 3.2.1.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for informational purposes only.
1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
1.6 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 this specification.
