ASME A112.3.1-2007 pdf download.Stainless Steel Drainage Systems for Sanitary DWV, Storm, and Vacuum Applications, Above- and Below-Ground.
1 GENERAL 1.1 Scope This Standard establishes material, dimensions, mechanical, and physical (including marking) require- ments for socket-type, seam-welded, stainless steel pipe, fittings, joints, and drains for use in plumbing sanitary and storm, drain, waste, and vent (DWV), and vacuum systems. It includes minimum requirements for work- manship, dimensions, weld strength, pressure testing, and marking that incorporates a push-fit joining method. NOTE: Material suitability for specific chemical applications shall be determined by a qualified engineer or ascertained from the manufacturer. 1.2 Units of Measurement Values are stated in the International System of units (SI) and in U.S. Customary (Inch) units. The SI units shall be considered as the standard. 1.3 Reference Standards The following is a list of publications referenced in this Standard. The latest edition shall apply.

Where a metallic or composition flashing is attached, the clamping device shall be secured with a ring or collar to the drain. DWV: drain, waste, and vent. EPDM: ethylene propylene diene monomer. extension: a device used to raise a grate to floor level where necessary.
filter basket: a perforated device inserted in a drain body to minimize debris before it enters the drain line. floor cleanout: a pipe fitting with a cover, which permits access to a drain line from a finished floor level. floordrain: a manufactured receptacle designedtoreceive and convey drainage runoff from finished or unfinished floor areas, including showers. FPM: fluorine rubber. hinged grate: used where access to a drain is required without completely removing a secured grate. joint component: any gasket, collar, clamp, or other device used to connect pipe to pipe or pipe to fitting, in the form of a mechanical joint. mill certificate: a certificate certifying a specific quality. NBR: nitrile rubber. nominal: for identification only, not the measurement of size of pipe. open area: total area ofthe drainage openings in the grate. passivate: to treat or coat (a metal), in order to reduce the chemical reactivity of its surface. pickle: a chemical solution, such as an acid, that is used to remove scale and oxides from the surface(s) of metals. push-fit joint: a method of manually joining a spigot and socket. removable trap: a trap assembly that is made of Type 316L that shall be equipped with a removable water seal ele- ment to facilitate cleaning of the drain. secondary strainer: an additional strainer set in the base ofthe drain body sump thatminimizes debris thatmight pass through grate openings. sediment bucket: a device used to minimize debris before it enters the drain lines. socket: the female end of a piece of pipe, fitting or drain. spigot: the male end of a piece of pipe, fitting or drain. trap primer connection: a tapped boss on drain body used to receive discharge from a trap primer valve or other priming device. trench drain: a long, narrow, manufactured receptor designed to receive and convey to the drainage system, runoff water, or other liquids from the area immediately adjacent to the building structure.
