1. Scope

1.1 This standard specifies the basic requirements of material, dimensions and testing of valve fittings for liquefied petroleum gas (LPG) gas cylinders of more than 5 litre water capacity. It covers valves with taper stems only.

1.2 Valve fittings for LPG cylinders of water capacity up to 5 litre are covered in a separate standard IS 8776 ‘Valve fittings for use with LPG cylinder up to and including 5 litre water capacity’.
