Reaffirmed 2024

1. SCOPE

1.1 This standard covers requirements for cast iron special castings to be used with cast iron and ductile iron pressure pipes for carrying water, and sewage for sizes from DN 80 mm up to DN 1 600 mm.

1.2 This standard is applicable to fittings meant for mechanical joints (bolted gland), push-on-joints (singlerubber gasket) and flanged joints.

1.2.1 The standard does not restrict the use of other types of joints as long as overall dimensions are maintained for reasons of safety and interchangeability.

1.3 The design of the socket and gasket are not within the scope of this standard.

1.4 The fittings are suitable for fluid temperatures between 0°C and 50°C excluding frost.

NOTE - The terms ‘special castings’ and ‘push-on flexible joints’ have been referred as ‘castings’ and ‘push-on joints’ respectively henceforth in this standard
