ASTM A74-06

Standard Specification for Cast Iron Soil Pipe and Fittings

SCOPE
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
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. Metric conversions in are to two decimal places; all other metric conversions are rounded to the nearest whole number.
