Specifies requirements for ductile iron pressure pipes centrifugally cast in moulds and ductile iron fittings, of nominal sizes up to and including DN 750. The specified pipes and fittings are intended primarily for conveying water under pressure but they may be used for conveying sewage or other liquids. Two classes of pipes, K9 and K12, are specified on the basis of wall thickness.

This Standard specifies requirements for ductile iron pressure pipes centrifugally cast in moulds and ductile iron fittings of nominal sizes up to and including DN 750.The specified pipes and fittings are intended primarily for conveying water under pressure, but they may be used for conveying sewage or other liquids.NOTE: Purchasing guidelines are given in Appendix A.This Standard specifies two classes of pipe, namely K9 and K12 (also specified in ISO 2531 and BS 4772) on the basis of wall thickness.Maximum allowable operating pressures and allowable site test pressures for pipes and fittings installed in the field are given in Appendix B, test procedures for tensile and hardness testing are described in Appendix C while works hydrostatic test pressures are given in Appendix D.NOTE: Ductile iron is a casting material that is iron and carbon-based, the latter element being present principally as graphite in spheroidal or nodular form. Spheroidal or nodular graphite gives ductile iron mechanical properties superior to those of flake-graphite iron. Ductile iron is also known as spheroidal graphite iron, SG iron or nodular graphite iron.
