Причина отмены This specification covers metal mechanical cold flare compression fittings with integral disc spring suitable for use with cross-linked polyethelene PEX plastic tubing in ³/₈ , ¹/₂ , ⁵/₈ , and ³/₄ nominal diameters. that meets the requirements of Specifications F876 and F877. These fittings are intended for use in 100 psi (689.5 kPa) cold and hot water distributions systems and hydronic heating systems operating at temperatures up to and including 180°F (82°C). Included are the requirements for materials, workmanship, dimensions, and markings to be used on the fittings.

Formerly under the jurisdiction of Committee F17 on Plastic Piping Systems, this specification was withdrawn in January 2018 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
