UL Outline of Investigation for Hose Nozzle Valves for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 – E85) (Issue 5)
These requirements cover hose nozzle valves that are 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 29??(minus 20?? to 52??(125?? and an operating pressure of minimum 50 psi (350 kPa). 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 Specification for Automotive Spark- Ignition Fuel@ ASTM D4814; b) Gasoline/ethanol blends with nominal ethanol concentrations up to 25 percent ethanol (E25)@ consisting of gasoline formulated in accordance with the Standard Specification for Automotive Spark-Ignition Fuel@ ASTM D4814@ when blended with denatured fuel ethanol formulated to be consistent with the Standard Specification 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 Specification in item (b) or formulated in accordance with the Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines@ ASTM D5798. 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. These requirements do not cover the following: a) Hose nozzle valves for handling liquids under cryogenic conditions. 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. c) Hose nozzle valves operated wholly or partially by electricity or battery. This outline does not cover hose nozzle valves for use with diesel@ biodiesel@ diesel/biodiesel blends@ kerosene or fuel oil@ which are covered under the Outline of Investigation for Hose Nozzle Valves for Diesel Fuel@ Biodiesel Fuel@ Diesel/Biodiesel Blends With Nominal Biodiesel Concentrations Up To 20 Percent (B20)@ Kerosene@ and Fuel Oil@ UL 2586B. This outline does not cover hose nozzle valves for use with liquefied petroleum gas (LP-Gas)@ which are covered under the Standard for Flow Control Valves for Anhydrous Ammonia and LP-Gas@ UL 125. Requirements for the installation and use of these dispensing devices are included in the Code for Motor Fuel Dispensing Facilities and Repair Garages@ NFPA 30A.
