    ASTM F2945

    Abstract

    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. 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

    Annex A1

    In-Plant Quality Control for sizes up to 12 in.

    Annex A2

    PA-11 Butt Fusion Fittings

    Appendixes

    Subject

    Appendix X1

    Butt Fusion Guidelines for PA-11 Piping

    Appendix X2

    Design Consideration


    1.5 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 1Heat 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.).
