Description / Abstract:
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.
