Standard Specification for Polyamide 11 (PA 11) and Polyamide 12 (PA12) Mechanical Fittings for Use on Outside Diameter Controlled Polyamide 11 and Polyamide 12 Pipe and Tubing

ABSTRACT
This specification describes requirements and test methods for the qualification of Polyamide 11 (PA 11) bodied mechanical fittings for use with outside diameter controlled PA 11 pipe, and nominal 2 pipe size (IPS) and smaller. In addition, it specifies general requirements of the material from which these fittings are made. Performance requirements shall include tests to determine elevated temperature sustained pressure, tensile strength, in-line fitting, mechanical saddle fittings, temperature cycling, and joint constant tensile load.
SCOPE
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.

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.

NOTE 1—For over 40 years D2513 was the singular US CFR Title 49 Part 192 referenced Standard Specification codifying the installation and use of
thermoplastic gas piping in jurisdictional installations. Initially all materials (PE, PVC, ABS, CAB) were contained within the body of the standard D2513.
In later years D2513 was completely reformatted to make it more user friendly by moving material-specific requirements from the standard’s body to
mandatory annexes. The next major change occurred late in 2009 at which time all thermoplastic materials, except polyethylene, were removed from
D2513 changing its Title and Scope from a thermoplastic gas piping standard to a polyethylene-only gas piping standard. This recent change required
that new standards be developed for those materials that were
