Abstract

This specification covers cast gray iron soil pipe and fittings for use in gravity flow plumbing, drain, waste and vent sanitary, and storm water applications. These pipe and fittings are not intended for pressure applications. The cast iron shall be produced by an established commercial method that provides control over chemical and physical properties. Castings shall be sound, true to pattern, and of compact close grain that permits drilling and cutting by ordinary methods and its interior surface shall be reasonably smooth and free from defects. Ferrous scrap, pig iron, and any recycled ferrous material to be used in the melting operation shall be screened for radioactivity. Tension test shall include breaking load, machined diameter, and tensile strength. Chemical test shall conform to the chemical composition requirements prescribed for phosphorous, sulfur, chromium, titanium, aluminum, lead, and carbon equivalent. Dimension requirements for hub, spigot, barrel, grooves, water seal and trap, and threads of the pipe and fittings are detailed. The pipe and fittings shall be uniformly coated with a material suitable for the purpose.

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.
