Anotace textu normy ASTM F2159-23a :
This specification establishes requirements for sulfone plastic insert fittings utilizing a copper crimp ring for SDR9 cross-linked polyethylene (PEX) tubing for cold- and hot-water distribution systems. Material for fitting shall be molded from sulfone plastic. Molded part shall not crack, split, or shatter and be free of visible splay. Fittings shall be tested for performance requirements such as hydrostatic burst, hydrostatic sustained pressure strength, thermocycling, excessive temperature-pressure capability, dimensions, workmanship, finish, appearance, assembly, crimp joint, and insert crush test.

1.1?This specification establishes requirements for sulfone plastic insert fittings and copper crimp rings, or alternate stainless steel clamps for four sizes Nominal Tubing Sizes (NTS) (3/8?, 1/2?, 3/4?, and 1) of cross-linked polyethylene (PEX) tubing that meet the requirements for Specification F876 or Specification F3253, or polyethylene of raised temperature (PE-RT) tubing that meet the requirements of Specification F2623 or Specification F2769. These fittings are intended for use in 100 psi (690 kPa) cold- and hot-water distribution systems operating at temperatures up to and including 180 ?F (82 ?C). Included are the requirements for material, molded part properties, performance, workmanship, dimensions, and markings to be used on the fittings and rings. 1.1.1?When used with PEX tubing in accordance with Specification F876, the fittings covered by this specification are intended for use in, but not limited to, residential and commercial, hot- and cold-potable water distribution systems, reclaimed water, fire protection, municipal water service lines, building supply lines, radiant heating and cooling systems, hydronic distribution systems, snow and ice melting systems, geothermal ground loops, district heating, turf conditioning, compressed air distribution, and building services pipe. 1.1.2?When used with PEX tubing in accordance with Specification F3253, the fittings covered by this specification are intended for use in residential and commercial hydronic heating and cooling systems. 1.1.3?When used with PE-RT tubing in accordance with Specification F2769, the fittings covered by this specification are intended for use in residential and commercial, hot- and cold-potable water distribution systems, and building supply lines. 1.1.4?When used with PE-RT tubing in accordance with Specification F2623, the fittings covered by this specification are intended for use in general fluid transport, including hydronics and irrigations systems. 1.2?Included are the requirements for material, molded part properties, performance, workmanship, dimensions, and markings to be used on the fittings and rings. 1.3?The following is an index of the appendix in this specification:
1.4?UnitsThe 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. 1.5?The following precautionary caveat pertains only to the test method portions, Sections 11 and 12, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
