This standard specifies the requirements for sand cast iron spigot and socket pipes, fittings, and accessories used for above-ground soil, waste, and ventilating non-pressure drainage pipelines.

Covers general requirements, dimensions, and manufacturing of hot rolled steel rails for railway tracks.

Quick Reference Values
hydrostatic test pressure0.07 MPa (0.7 kg/cm²) for 15 seconds
tolerance on weight-10 percent
tolerance on wall thickness-15 percent
standard effective lengths1.5m, 1.8m, 2.0m
Practical Notes
Pipes should be struck with a light hammer before installation; a clear ringing sound indicates the absence of cracks or severe casting defects.
Ensure proper alignment and adequate jointing (traditionally lead caulking) at the spigot and socket ends to prevent leaks in vertical stacks.
Although revised in 2002 to include ductile iron, the 1979 version is widely referenced in legacy plumbing maintenance and standard schedules of rates.
