Standard Specification for Polyamide 11 Gas Pressure Pipe, Tubing, and Fittings
 N F2945

Annotation

This specification covers requirements and test methods for the characterization of polyamide 11 pipe, tubing, and fittings for use in fuel gas pipelines. The pipe and fittings covered by this specification are intended for use in the distribution and transmission of fuel gases.

This specification does not cover threaded pipe. Generic fusion guidelines are given in Appendix X1. Design considerations are discussed in Appendix X2. In-plant quality control programs are specified in Annex A1.

The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.

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.

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.

NOTE 1—Heat fusion joining of PA11 pipe and fittings meeting the requirements of this standard is limited to PA11 pipe and fittings meeting the requirements of this Standard. Heat Fusion joining of PA11 pipe and fittings meeting the requirements of this standard is not allowed to pipes and fittings made from any other thermoplastic materials (for example, PA12, PEs, PVCs, etc.).
