UL 2586C OUTLINE
UL Outline for Investigation Hose Nozzle Valves for Diesel Exhaust Fluid
|Publication Date:||8 October 2014|
These requirements cover hose nozzle valves that are intended to be used for the control of Diesel Exhaust Fluid (DEF). Hose nozzle valves covered by this outline are for use with DEF which are handled at temperatures within the range of minus 20°C (minus 4°F) to 52°C (125°F) and an operating pressure of minimum 50 psi (350 kPa).
Hose nozzle valves covered by these requirements are intended for use with DEF defined as a liquid with 67.5 percent deionized water and 32.5 percent urea.
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 flammable liquids, 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 gasoline or gasoline/ethanol blends which are covered under the Outline of Investigation for Hose Nozzle Valves for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 - E85), UL 2586A or 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.
