1.1 This specification describes requirements and test methods for the qualification of Polyamide 11 (PA 11) and Polyamide 12 (PA 12) bodied mechanical fittings for use with outside diameter controlled PA 11, nominal 2 pipe size (IPS), and smaller complying with Specification F2945 , and PA 12, nominal 2 pipe size (IPS), and smaller complying with Specification F2785 . In addition, it specifies general requirements of the material from which these fittings are made. 1.2 The test methods described in this specification are not intended to be used as routine quality tests. 1.3 This specification covers the types of mechanical fittings covered in 3.2.1 . 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 following safety hazards caveat pertains only to the test methods 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. 1.6 The text of this specification 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. 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.
