Specifies technical requirements for ductile iron pressure pipes and fittings. Working pressure has been increased to 1600 kPa. Fittings covered by This Standard are primarily for use with water supply pressure pipes having compatible outside diameters, but can be used with other pressure pipes by means of suitable adaptors. Hydrostatic test pressures are included. Raised face ductile iron flanges appropriate for the fittings in This Standard follow ISO requirements, and may be drilled for compatibility with Tables C, D, and E of AS 2129, Flanges for pipes, valves and fittings, for standard pressure, or Tables F and H for high pressure.
