Standard Specification for Cast Iron Soil Pipe and Fittings
2021
45
ASTM Vol.01.02 (2023)
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.
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.
