CISPI Standard 301:
Specification for hubless cast iron soil pipe and fittings for sanitary and storm drain, waste, and vent piping applications
The purpose of this standard is to establish standards covering material, dimensions, and tolerance for pipe and fittings for hubless cast iron sanitary and storm drain, sanitary waste, and vent piping applications.
Cast iron is the premier piping material for sanitary and storm drain, waste, and vent applications. It has been used in these applications for hundreds of years and is for nonpressure applications where temperatures will not exceed 212 F.
It is the most durable DWV piping system available and can be used in all types of construction. It has high crush strength, is noncombustible, and offers superior sound-deadening performance.
