1.1 This specification covers requirements and test methods for the characterization of polyamide 66 (PA66) compounds, pressure or non-pressure piping (pipe, tubing, and fittings) for regulated or non-regulated oil- and gas-producing (gathering) applications to convey fluids such as oil, gas, multiphase fluids, and nonpotable oilfield water. This specification does not cover piping for regulated gas distribution or gas transmission applications. NOTE 1-Regulated gas gathering, distribution, and transmission lines are addressed in federal codes such as CFR 49 Part 192 (United States) or CSA Z662 (Canada). For regulated applications, waivers or special permits may be required by the authority having jurisdiction. 1.2 Pipe and tubing sizes in this specification range from IPS through IPS 10 and from CTS through CTS 1-1/4. 1.3 In-plant quality control programs are specified in Annex A1. Fusion joining guidelines are addressed in Appendix X1. Design and installation considerations are discussed in Appendix X2. NOTE 2-Appendix X1 Heat fusion joining techniques for PA66 pipe, tubing, and fittings meeting the requirements of this specification are intended for use exclusively with PA66 pipe, tubing, and fittings manufactured in accordance with this specification. Heat fusion joining between PA66 pipe, tubing, and fittings with PA 323 (PA-11) or PA 423 (PA-12) pipe, tubing, and fittings is not permitted. 1.4 The text of this specification references notes, footnotes, and appendixes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The values given in parentheses are mathematical unit conversions that are provided for information only and are not considered standard. 1.6 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.
