1 Scope

1.1 These requirements cover hose nozzle valves that are intended to be used for the control of flammable and combustible liquids. They are of the type used in motor fuel dispensing equipment. Hose nozzle valves covered by this standard are for use with flammable and combustible liquids which are handled at temperatures within the range of -20°F (-29°C) to 125°F (52°C) and an operating pressure of minimum 50 psi (350 kPa).

1.2 These requirements cover hose nozzle valves of the manually operated and automatic pressure operated type. When they form a part of an assembly which provides for additional functions or service, the requirements are outside the scope of these requirements.

1.3 These requirements do not cover the following:

1. a) Hose nozzle valves for handling liquids under cryogenic conditions.

2. b) Hose nozzle valves for general refinery service, offshore and pipe line terminals, natural gas processing plants, gas distribution systems, petrochemical processing facilities, or the like.

3. c) Hose nozzle valves operated wholly or partially by electricity or battery; or

4. d) Hose nozzle valve readers that are powered from internal batteries. These are covered under UL 1238A, Outline of Investigation for Battery Operated Hose Nozzle Valve Readers.
