22、e intended to be used for the control of motor fuels as indicated in 1.2. They are of the type used in motor fuel dispensing equipment. Hose nozzle valves covered by this standard are for use with motor fuels which are handled at temperatures within the range of minus 29C (minus 20F) to 52C (125F) a

23、nd an operating pressure of minimum 50 psi (350 kPa). 1.2 Hoze nozzle valves covered by these requirements are intended for use with one or more of the following as applicable: a) Gasoline formulated in accordance with the Standard Specication for Automotive Spark- Ignition Fuel, ASTM D4814; b) Gaso

24、line/ethanol blends with nominal ethanol concentrations up to 25 percent ethanol (E25), consisting of gasoline formulated in accordance with the Standard Specication for Automotive Spark-Ignition Fuel, ASTM D4814, when blended with denatured fuel ethanol formulated to be consistent with the Standard

25、 Specication for Denatured Fuel Ethanol for Blending With Gasolines For Use as Automotive Spark-Ignition Engine Fuel, ASTM D4806; or c) Gasoline/ethanol blends with nominal ethanol concentrations above 25 percent formulated in accordance with the Standard Specication in item (b) or formulated in acc

26、ordance with the Standard Specication for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines, ASTM D5798. 1.3 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 additi

27、onal functions or service, the requirements are outside the scope of these requirements. 1.4 These requirements do not cover the following: a) Hose nozzle valves for handling liquids under cryogenic conditions. b) Hose nozzle valves for general renery service, offshore and pipe line terminals, natur

28、al gas processing plants, gas distribution systems, petrochemical processing facilities, or the like. c) Hose nozzle valves operated wholly or partially by electricity or battery. 1.5 This standard does not cover hose nozzle valves for use with diesel, biodiesel, diesel/biodiesel blends, kerosene or

31、 use of these dispensing devices are included in the Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A. 2 General 2.1 Components 2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for that component. 2.1.2 A c

32、omponent is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance wi

33、th its rating established for the intended conditions of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and

34、shall be used only under those specic conditions. 2.1.5 A hose nozzle valve with an integral swivel shall be additionally evaluated to the Electrical-Continuity and Operation Tests in the Standard for Emergency Breakaway Fittings, Swivel Connectors and Pipe-Connection Fittings for Gasoline and Gasol

35、ine/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 E85), UL 567A. The force is to be applied at the point on the swivel farthest from the joint. When necessitated by the swivel construction, this test is to be conducted on additional samples of the swivel with the load appli

36、ed on the opposite side of the plane of rotation. See UL 567A, Figures 16.1 16.3 for examples.

38、or the purpose of this standard, the following denitions apply. 3.2 BLENDING OPTION Dispensing devices may be provided with an option that blends two specic fuels into one fuel to be dispensed. This blending occurs at the dispenser level and can be in two forms: a) Fixed blending Blending at the dis

39、penser level that blends two specic fuels into one fuel to be dispensed, and that fuel to be dispensed is xed. For example, xed blending includes blend options where gasoline and denatured fuel ethanol can be blended to achieve E85, which is the actual dispensed fuel. b) Variable blending Blending a

40、t the dispenser level that blends two specic fuels into the fuel to be dispensed, but the fuel to be dispensed can be any of a number of previously set points. For example, variable blending includes blend options where gasoline and E85 can be blended to achieve E40, E60, and E85 as the actual dispe

41、nsed fuel. 3.3 GASOLINE/ETHANOL BLENDS Blended fuels composed of a gasoline component and an ethanol component. The numerical value corresponding to the ethanol component determines the blend rating (such as E85 for 85% ethanol, 15% gasoline). 3.4 HOSE NOZZLE VALVE, AUTOMATIC A hose nozzle valve whi

42、ch is held open during the entire lling operation. It may be held open by manual force or by an integral hold-open or latching device. It incorporates a mechanism that shuts off the ow of liquid during refueling operations to prevent overow from the ll opening when liquid reaches a predetermined poi

43、nt on the spout. 3.5 HOSE NOZZLE VALVES A self-closing device designed to control the ow of ammable and combustible liquids at an operating pressure of minimum 50 psi (345 kPa). It is intended for use at the outlet end of a hose for dispensing ammable liquids. 3.6 HOSE NOZZLE VALVE, MANUALLY OPERATE

44、D A hose nozzle valve that is manually held open during the entire lling operation and closes only upon release of the manual force. 3.7 HOSE NOZZLE VALVE, VAPOR RECOVERY A system constructed to capture vapors displaced during lling operations. The vapors are not processed during the course of this

45、activity. a) Assist Nozzle A vacuum or pump is used to draw the vapors back to tank. b) Balance Nozzle Displacement of vapors from tank being ll forces the vapor back into the storage tank.
