1.1 This specification covers requirements and test methods for the characterization of polyamide 66 pipe, tubing, and fittings for use in fuel gas, oil and gas, and gas transmission applications. Pipe sizes in this specification range from to 8 NPS (IPS) and to 1-1/4 NTS (CTS). The pipe and fittings covered by this specification are intended for use in the distribution and gathering or transmission of methane gas. 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 that 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 the 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 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 before use. NOTE 1-Pipe and fittings using heat fusion joining techniques produced from compounds meeting the requirements of Group 1, Class 5, and Grade 1 (PA151 or PA66) are intended for use with pipe and fittings manufactured from compounds meeting the requirements of Group 1, Class 5, and Grade 1. As per the recommendations of the respective resin manufacturers, no cross fusion between PA 151 (PA66), PA 323 (PA11), and PA 423 (PA12) compounds is permitted.
