Historical Standard: ASTM A74-03 Standard Specification for Cast Iron Soil Pipe and Fittings
SUPERSEDED (see Active link, below)
ASTM A74
1. Scope
1.1 This specification covers cast iron soil pipe and fittings for use in gravity flow applications. It establishes standards covering material, principal 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 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 requirements given herein.
