ASTM WK44998

    New Specification for Special Cast Iron Hubless Fittings used in Single Stack Drain Waste and Vent applications

    (What is a Work Item?)

    Developed by Subcommittee: A04.12 | Committee A04 | Contact Staff Manager


    1. Scope

    This specification covers hubless cast iron offset closet tees and crosses and related fittings needed to design and construct single stack drain waste and vent systems in multi story buildings.

    ASME has withdraw a standard for offset closet tees and crosses used in DWV systems for multi story buildings. Because the pipes, fittings and couplings that are used with these special fittings are covered by ASTM standards under the jurisdiction of the A04.12 subcommittee they felt the expertise in the ASTM A04.12 subcommittee could be used to write a replacement standard.
