UL-87B:2015 pdf reee download – STANDARD FOR SAFETY Standard for Power-Operated Dispensing Devices for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil.
3.10 HANGING HARDWARE — The portion of the dispensing device that is connected to the outlet of the dispenser and consists of a hose assembly and hose nozzle valve, and with emergency breakaway couplings and swivel connectors as needed.
3.11 HOUSING — That section of the device that encloses and is intended to protect operating parts, control mechanisms, or other mechanical or electrical components, the damage of which would render the device incapable of being operated as intended, lead to tampering, introduce the possibility of escape of liquid, or expose bare live electrical parts.
3.12 INTENDED CARE AND USAGE — Intended care means tasks such as lubrication and cleaning. Intended usage covers the manipulations involved in starting the dispenser, dispensing the liquid, and restoring the dispenser to its standby condition.
3.13 MASTER-SATELLITE DISPENSER COMBINATION — Consists of two or more dispensing devices. The “Master” dispenser controls the dispensing operation; the “Satellite” dispenser actually dispenses as well, but is not used to control the dispensing function.
3.14 PANEL — A principal section of a housing or enclosure. A mounting arrangement for control and other components.
3.15 PEDESTAL — That part of the structure above the base which supports the component units, and to which they are attached.
3.16 PUMPING UNIT — A power-operated pump for diesel or diesel/biodiesel blends, which may incorporate a strainer, air separator, relief device, or other auxiliary part.
3.17 SEALS, DYNAMIC — A seal that is subject to mechanical movement or other applied forces that result in movement or flexing of the seal under normal use conditions.
3.18 SEALS, STATIC — A seal that is not subject to mechanical movement or other applied forces other than compressing forces that are applied during installation and maintained during normal use conditions.
3.19 UNCLASSIFIED AREA — An area within a dispenser housing isolated from Division 1 or Division
2 locations by a vapor barrier or a solid nozzle boot, but not completely surrounded by a Division 1 or Division 2 area, that does not contain a level of flammable gases or vapors that are capable of producing explosive or ignitable mixtures.
3.20 VAPOR BARRIER — A solid, unpierced partition located between Division 1 or Division 2 locations and unclassified areas of a dispensing device. The vapor barrier is intended to reduce the entry of flammable gases or vapors into unclassified areas.
CONSTRUCTION
4 General Construction
4.1 General
4.1.1 A power-operated dispensing device includes as needed a base, housing or pedestal, power-operated pump, pressure relief device, strainer, meter, valves as required, hose, hose nozzle valve, motor control, locking mechanism, piping, electrical wiring, and fixtures. The pump may be integral with the dispensing device, or the dispensing device may be designed for use with a separate pump.
4.1.2 A dispensing device may be of the self-contained type with components mounted in a common pedestal and housing, or it may comprise separate assemblies intended for installation as individual units but in conjunction with each other.
4.1.3 Devices having self-contained pumping units are judged on the use of suction lifts of not less than 2 feet (61 cm).
