Scope of standard 1.1 This specification covers cast iron soil pipe and fittings for use in gravity flow plumbing, drain, waste and vent sanitary, and storm water applications. It establishes standards covering material, manufacture, mechanical and chemical properties, coating, test methods, inspection, certification, product markings, dimensions, and dimensional tolerances for extra heavy and service cast iron soil pipe and fittings. These pipe and fittings are not intended for pressure applications as the selection of the proper size for sanitary drain, waste, vent, and storm drain systems allows free air space for gravity drainage. 1.2 This specification covers pipe and fittings of the following patterns and, when so designated, shall apply to any other patterns that conform with the applicable requirements given in this specification. 1.2.1 Pipe: TablesExtra heavy, 2½ ft (0.75 m), 3½ft (1.0 m), 5 ft (1.5 m), 10 ft (3.0 m) lengths1, 2 Service, 2½ ft (0.75 m), 3½ft (1.0 m), 5 ft (1.5 m), 10 ft (3.0 m)1, 2Outside dimensions (for detailing)X1.11.2.2 Fittings: Tables¼ bends; long ¼ bends3, 4¼ bends, long low-hub5¼ bends, low heel; high heel6, 7¼ bends, short sweep; long sweep8¼ bends, reducing long sweep91/5 bends101/6 bends101/8 bends; long 1/8 bends111/16 bends 11Y branches12, 13Y branches, combination 1/8 bends, single14Y branches, combination 1/8 bends, double14Sanitary T branches, single15Sanitary T branches, double15Sanitary T branches, cleanout16Tapped sanitary T branches, single17Tapped sanitary T branches, double17T branches, single and double18Tapped T branches, single19Tapped T branches, double19T branches, cleanout20-45° offset fitting21Double hubs22Long double hubs22Reducers23Increasers24, 25P traps26, 27Deep seal P traps28Running traps29Screw plugs (brass)30Blind plugs31Iron-body ferrules32Side inletsFig. 3Closet bends33Tapping bosses34Reducing ¼ bend SV35Combination Y and 1/8 bend36‘H' branch fitting371.3 The values stated in inch-pound units are to be regarded as standard.
