ASTM D3309-96a(2002)

Standard Specification for Polybutylene (PB) Plastic Hot- and Cold-Water Distribution Systems (Withdrawn 2010)

ABSTRACT
This specification covers requirements, test methods, and methods of marking for polybutylene plastic system components. These components comprise pipe and tubing, socket-fusion fittings, compression fittings, mechanical fittings, and plastic-to-metal transition fittings. The components covered by this specification are intended for use in hot- and cold-water potable water service and distribution systems and such non-potable water applications. The components are classified as follows: pipe, tubing, and socket-fusion fittings; plastic-to-metal transition fittings; and compression and mechanical plastic fittings. The following tests shall be performed: sustained hydrostatic pressure; thermocycling; hydrostatic burst strength; assembly; excessive temperature and pressure capability of tubing and pipe; and elongation value at break.
SCOPE
1.1 This specification covers requirements, test methods, and methods of marking for polybutylene plastic system components made in one standard dimension ratio and intended for 0.69 MPa (100 psi) water service up to and including 82°C (180°F). These components comprise pipe and tubing, socket-fusion fittings, compression fittings, mechanical fittings, and plastic-to-metal transition fittings. Requirements and test methods are included for sustained, hydrostatic pressure strength, thermocycling resistance, joint strength, and dimensions and tolerances for pipe and socket fusion fittings. The components covered by this specification are intended for use in hot- and cold-water potable water service and distribution systems and such non-potable water applications as building services piping, water heating and cooling systems, fire sprinkler applications, and other miscellaneous applications involving the transport of water, ethylene glycol solutions, or other aqueous liquids shown not to adversely affect PB performance.
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 in SI units are the standard. The values stated in parentheses are for information only.
Note 1—Suggested hydrostatic design stresses and hydrostatic pressure ratings for pipe, tubing, and fittings are listed in Appendix X1. Design, assembly, and installation considerations are discussed in . An optional performance qualification and an in-plant quality control program are recommended in Appendix X3.
1.4 The following precautionary caveat pertains only to the test method 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.
