1.1 This specification covers polybutylene (PB) tubing that is outside diameter controlled, made in standard thermoplastic tubing dimension ratios and pressure rated for water (see Appendix). Included are criteria for classifying PB plastic tubing; a system of nomenclature for PB plastic tubing; and requirements and test methods for materials, workmanship, dimensions, sustained pressure, and burst pressure. Methods of marking are also given.
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 the standard. The values given in parentheses are provided for information purposes only.
1.4 The following safety hazards caveat pertains only to the test methods portion, Section 7, of this specification: 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.
