This Standard applies to in line-valves for use in radiant heating systems, and hot and cold water cross linked polyethylene (PEX) distribution systems which are compliant with the requirements identified in ASTM F877 for PEX tubing systems. Valves meeting these requirements are rated for a minimum 100 psi (0.69 MPa) at 180° F (82° C).

This Standard is supplemental to ASTM F877 and identifies additional requirements specific for valves. This Standard covers components intended for use in residential and commercial, hot and cold, potable water distribution systems; and sealed central heating, including under-floor heating systems. This Standard excludes supply stops and fixture fittings (faucets).
