This British Standard specifies the requirements for cast iron drain systems for use in buried applications or suspended within a basement, in areas not subject to fire regulations, where any pressure likely to occur is a maximum of 3.5 bar.
NOTE In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).
The nominal sizes of the drain systems are DN 100, DN 150 and DN 225 inclusive.
The standard specifies the requirements for materials, dimensions and tolerances, mechanical properties and surface condition for cast iron pipes and fittings. It also indicates performance requirements for all components, including joints.
