15、 and equipment. Its first organizational meetingwas held on July 22, 1958, and Panel No. 21 was created on May 1, 1964 to establish standardsfor roof drains, floor drains, backwater valves, and other drainage specialties. Its scope was therecommendation of suitable existing standards in cooperation
16、with interested sponsors or thedevelopment of adequate new standards as needed for roof drains, floor drains, and other drainsas used or installed in plumbing systems. The Committee has since been reorganized as an ASMEStandards Committee.The ASME A112 Committee was restructured in 1998 in accordanc
17、e with the ASME RedesignProcess, and Panel 21 Working Group 1 became Project Team 6.3. The Project Team met twice toupdate this Standard, which now includes criteria from the International Association of Plumbingand Mechanical Officials (IAPMO), PS 4 and PS 16.This Standard was approved as an Americ

24、NCH DRAINS1 GENERAL1.1 ScopeThis Standard covers floor, area, adjustable floor, andtrench drains that are used inside of, or outside andimmediately adjacent to, building structures. ThisStandard specifies design requirements, definitions,nomenclature, outlet types and connections, grate-freeareas, t
25、op-loading classifications, materials, and fin-ishes. Seam-welded, socket-type, stainless steel fabri-cated drains are covered in ASME A112.3.1.1.2 AlternativesThe requirements of this Standard are not intendedto prevent the use of alternative designs, materials, ormethods of construction, provided
26、such alternativesmeet the intent and requirements of this Standard.1.3 Units of MeasurementThe values stated in either SI (metric) or U.S. Custom-ary (yard/pound) units of measure are equivalent inapplication; however, each system is to be used indepen-dently of the other. In this Standard, U.S. Cus
27、tomaryunits are shown in parentheses. Combining values fromthe two systems can result in nonconformance with theStandard.1.4 IllustrationsThe illustrations included in this Standard areintended only to describe and portray typical drainsand are not intended to restrict design or to specifyrequiremen
