Fuels, as dened by these requirements, include one or more

26、of the fuels described in 1.2. 1.2 Dispensing devices covered by these requirements are intended for use with one or more of the following: a) Diesel fuel and diesel fuel/biodiesel blends with nominal biodiesel concentrations up to 5 percent (B0 B5) formulated in accordance with the Standard Specica

27、tion for Diesel Fuel Oils, ASTM D975. b) Diesel/biodiesel blends with nominal biodiesel concentrations from 5 percent up to 20 percent (B6 B20) formulated in accordance with the Standard Specication for Diesel Fuel Oil, Biodiesel Blends (B6 B20), ASTM D7467. c) Biodiesel (B99.9/B100) formulated in a

28、ccordance with the Standard Specication for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels, ASTM D6751. d) Kerosene formulated in accordance with the Standard Specication for Kerosine, ANSI/ ASTM D3699. e) Fuel Oil (heating oil) formulated in accordance with the Standard Specication f

29、or Fuel Oils, ASTM D396. 1.3 Requirements for the installation and use of dispensing devices are included in the Code for Motor Fuel Dispensing Facilities and Repair Garages, ANSI/NFPA 30A, and the National Electrical Code, ANSI/NFPA 70. 1.4 These requirements apply to wiring methods used to install

30、 or interconnect such control equipment when the equipment is located directly on or within the housing of the dispensing device. 1.5 These requirements do not apply to control equipment that may authorize, monitor, or interrupt operation of a power-operated dispensing device, nor other auxiliary eq

31、uipment. These products would be covered under the Standard for Control Equipment for Use with Flammable Liquid Dispensing Devices, UL 1238. 1.6 These requirements do not cover dispensing devices for use with gasoline or gasoline/ethanol blends of any concentration. These dispensing devices are cove

32、red under the Standard for Power-Operated Dispensing Devices for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 E85), UL 87A. 1.7 These requirements do not cover dispensing devices for use with LP-Gas, which are covered under the Standard for Power-Oper

33、ated Dispensing Devices for LP-Gas, UL 495.

34、20 and B99.9/B100. 2 General 2.1 Components 2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for that component. 2.1.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic

35、 not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.1.4 Specic components are incomplete in co

36、nstruction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 2.2 Units of measurement 2.2.1 Values stated without par

37、entheses are the requirement. Values in parentheses are explanatory or approximate information. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3

38、Glossary 3.1 For the purpose of this standard, the following denitions apply. 3.2 AIR GAP A minimum of 1 inch (25.4 mm) free air space provided between the planes of Division 1 and Division 2 hazardous locations and an unclassied area of a dispensing device. 3.3 BASE The part of the assembly that is

39、 intended to be secured to the foundation on which the device will be installed. 3.4 CLASS I HAZARDOUS LOCATIONS Locations in which ammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. For the purpose of these requirements, as

40、applied to dispensing systems of other than the overhead type, the following classied areas are further dened. The area of the dispensing system covered by these requirements is the envelope dened by the maximum outer dimensions. a) Class I, Group D, Division 1 FEBRUARY 13, 2015 UL 87B 6UL COPYRIGHT

41、ED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 1) The area within a dispenser housing up to 4 feet (1.2 m) vertically above the base, except for that area dened as Division 2 or unclassied. 2) Any area within a nozzle boot. b) Class I, Group D, Divisio

42、n 2 1) Areas within a dispenser housing above the Division 1 area. 2) The area surrounding the dispenser housing within 18 inches (46 cm) horizontally in all directions from the Division 1 area located within the housing. 3) The area within 18 inches horizontally, in all directions from the opening

43、of a nozzle boot not isolated by a vapor tight partition, except that the area is not required to be extended around a 90 degree or greater corner. 3.5 DISPENSER, REMOTE CONTROL TYPE A dispensing device that does not contain a power- operated pump as part of the assembly, and which is intended for c

44、onnection to a uid piping system containing the power-operated pumps at a remote location. Also commonly identied as a “dispenser”. 3.6 DISPENSER, SELF-CONTAINED A dispensing device that includes a power-operated pump as part of the assembly. Also commonly identied as a “pump” or “suction dispenser”

45、. 3.7 DISPENSING DEVICE A product consisting of various components as applicable, which are used to control and meter the ow of liquid from an upstream storage device. 3.8 ELECTRICAL CIRCUITS a) High Voltage Circuit A circuit having a potential of not more than 600 volts and having circuit character

46、istics in excess of those of a low voltage or Class 2 circuit. b) Low Voltage Circuit A circuit involving a potential of not more than 30 volts ac (rms) (42.4 volts peak or dc) and 1) Supplied by a Class 2 transformer, or by a battery, by a battery and xed impedance, or by a transformer and xed impe

47、dance each of which, as a unit, is in compliance with what is required for a Class 2 transformer, or 2) Limited to a maximum of 100 volt-amperes. A circuit derived from a source of supply classied as a high voltage circuit, by connecting resistance in series with the supply circuit as a means of lim

48、iting the voltage and current, is not considered to be a low voltage circuit. c) Intrinsically Safe Circuit A circuit incapable of releasing sufficient electrical energy under normal or abnormal conditions to cause ignition of a specic hazardous atmospheric mixture. Abnormal conditions include unint
