ASTM-F2945 › Standard Specification for Polyamide 11 Gas Pressure Pipe, Tubing, and Fittings
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers requirements and test methods for the characterization of polyamide 11 pipe, tubing, and fittings for use in fuel gas piping. The pipe and fittings covered by this specification are intended for use in the transport of fuel gases. This specification does not cover threaded pipe. The polyamide 11 material used to make pipe and fittings shall be virgin or reworked material and shall have a Plastics Pipe Institute (PPI) long-term hydrostatic design stress and hydrostatic design basis rating as determined per PPI TR3 and PPI TR4. This specification deals with requirements for materials, requirements for pipe and fittings, test methods, marking, and quality Assurance.
Scope
1.1 This specification covers requirements and test methods for the characterization of polyamide 11 pipe, tubing, and fittings for use in fuel gas piping. The pipe and fittings covered by this specification are intended for use in the transport of fuel gases.
1.1.1 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.
1.2 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.
1.3 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.
1.4 The following is an index of the annexes and appendixes in this specification:
| Annexes | Subject |
