ASTM A 74:2021

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 dimensions found in Tables 1 and 2 and all other applicable requirements given in this specification. 1.2.1 Pipe: Tables Extra heavy, 2¹/₂ ft (0.75 m), 3¹/₂ ft (1.0 m), 5 ft (1.5 m), 10 ft (3.0 m) lengths 1, 2 Service, 2¹/₂ ft (0.75 m), 3¹/₂ ft (1.0 m), 5 ft (1.5 m), 10 ft (3.0 m) 1, 2 Outside dimensions (for detailing) X1.1 1.2.2 Fittings: Tables ¹/₄ bends; long ¹/₄ bends 3, 4 ¹/₄ bends, long low-hub 5 ¹/₄ bends, low heel; high heel 6, 7 ¹/₄ bends, short sweep; long sweep 8 ¹/₄ bends, reducing long sweep 9 ¹/₅ bends 10 ¹/₆ bends 10 ¹/₈ bends; long ¹/₈ bends 11 ¹/₁₆ bends 11 Y branches 12, 13 Y branches, combination ¹/₈ bends, single 14 Y branches, combination ¹/₈ bends, double 14 Sanitary T branches, single 15 Sanitary T branches, double 15 Sanitary T branches, cleanout 16 Tapped sanitary T branches, single 17 Tapped sanitary T branches, double 17 T branches, single and double 18 Tapped T branches, single 19 Tapped T branches, double 19 T branches, cleanout 20 -45° offset fitting 21 Double hubs 22 Long double hubs 22 Reducers 23 Increasers 24, 25 P traps 26, 27 Deep seal P traps 28 Running traps 29 Screw plugs (brass) 30 Blind plugs 31 Iron-body ferrules 32 Side inlets Fig. 3 Closet bends 33 Tapping bosses 34 Reducing ¹/₄ bend SV 35 Combination Y and ¹/₈ bend 36 ‘H' branch fitting 37 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
