UL 87C OUTLINE
UL Outline of Investigation for Power-Operated Dispensing Devices for Diesel Exhaust Fluid
|Publication Date:||24 March 2020|
These requirements apply to power operated dispensing devices, rated 600 V or less, for use with Diesel Exhaust Fluid (DEF). These requirements may be used to evaluate individual components of a dispensing device as indicated in 1.3 for use with DEF.
Dispensing devices 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.
In addition to the overall dispensing device, and in accordance with 1.1, these requirements shall apply to devices that are used to construct a dispensing device, including the following:
d) Electrically operated valves (for use with flammable liquids);
e) Hose nozzle valves;
f) Mechanically operated valves;
g) Hose assemblies;
h) Breakaway couplings;
i) Swivel connectors,
j) Pressure relief devices (for use with flammable liquids);
k) Mechanical line leak detectors;
l) Casting impregnation materials; and
m) Gaskets and seals.
Dispensing devices shall be installed and used in accordance with the applicable requirements in the Code for Motor Fuel Dispensing Facilities and Repair Garages, ANSI/NFPA 30A and the National Electrical Code, ANSI/NFPA 70.
These requirements apply to wiring methods used to install or interconnect such control equipment when the equipment is located directly on or within the housing of the dispensing device.
These requirements do not apply to control equipment that may authorize, monitor, or interrupt operation of a power-operated dispensing device, nor other auxiliary equipment. These products would be covered under the Standard for Control Equipment for Use With Flammable Liquid Dispensing Devices, UL 1238.
These requirements do not cover dispensing devices for use with any fluid other than as described in 1.2.
