本标准规定了用于控制易燃和可燃液体流量的软管喷嘴阀的最低要求。它们属于汽车燃油分配设备中使用的类型。本标准涵盖的阀门适用于在-40°C至+50°C温度范围内、工作压力不低于350 kPa的易燃和可燃液体。这些要求包括自动或手动操作的软管喷嘴阀，但完全或部分由电力操作的类型除外。它们可以构成提供附加服务功能的总成的一部分，其要求不在本标准的范围内。 这些要求不适用于带有蒸汽回收功能的软管喷嘴阀。

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.
