This Standard sets forth the minimum requirements for hose nozzle valves that are intended to be used to control the flow of flammable and combustible liquids. They are of the types used in motor fuel dispensing equipment. Valves covered by this Standard are for use with flammable and combustible liquids which are handled at temperatures within the range of -40 °C to +50 °C at a working pressure of not less than 350 kPa.
These requirements cover hose nozzle valves of the automatic or manually operated type, to the exclusion of types operated wholly or partially by electricity. They may form a part of an assembly that provides for additional functions of service, the requirements of which are outside the scope of this Standard. These requirements do not apply to hose nozzle valves incorporating a vapour recovery feature.
