Scope 1.1 These requirements cover products described in 1.3 when used with one or more of the fuels described in 1.4. 1.2 Pumps for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel shall be constructed to comply with the following: a) The requirements defined in the Standard for Power-Operated Pumps for Petroleum Dispensing Products, UL/ULC 79; and b) The requirements in this Standard. 1.3 This Standard sets forth minimum requirements for electrically-, hydraulically-, or pneumaticallydriven power-operated pumps for use with petroleum products in the following applications: a) Self-contained dispensing devices and submerged pumps used in storage tanks that provide the fuel to remote control dispensing devices. They are intended for operation at discharge pressures of 345 kPa (50 psig), or the marked maximum discharge pressure rating, when less, with the ambient and liquid temperature within the range of –29 °C (–20 °F) to 52 °C (125 °F). b) Dispensing systems to transfer the fuel from a tank or container to a vehicle or another container. They are intended for operation at the marked maximum discharge pressure, or less, with the ambient and liquid temperature within the range of –29 °C (–20 °F) to 52 °C (125 °F). c) Vapor recovery applications for dispensing devices. They are intended to operate under a vacuum at the inlet and a maximum discharge pressure of 345 kPa (50 psig), or marked discharge pressure, whichever is less. 1.4 Pumps covered by these requirements are intended for use with one or more of the following: a) Diesel Fuel, which includes renewable diesel and diesel/biodiesel blends with nominal biodiesel concentrations up to 5 % (B0 – B5) formulated in accordance with the Standard Specification for Diesel Fuel Oils, ASTM D975. b) Diesel/biodiesel, renewable diesel/biodiesel blends, blends with nominal biodiesel concentrations from 5 % up to 20 % (B6 – B20) formulated in accordance with the Standard Specification for Diesel Fuel Oil, Biodiesel Blends (B6 – B20), ASTM D7467. c) Biodiesel (B99.9/B100) formulated in accordance with the Standard Specification for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels, ASTM D6751. d) Kerosene formulated in accordance with the Standard Specification for Kerosine, ASTM D3699. e) Fuel Oil (Heating Oil) formulated in accordance with the Standard Specification for Fuel Oils, ASTM D396. 1.5 Products covered by this Standard are intended to be installed and used in accordance with the applicable Codes and Regulations as determined by the Authority Having Jurisdiction (AHJ), such as, but not limited to: a) In the United States: 1) Flammable and Combustible Liquids Code, NFPA 30; 2) Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A; 3) National Electrical Code, NFPA 70. b) In Canada: 1) Canadian Electrical Code, Part I Safety Standard for Electrical Installations, CSA C22.1; 2) National Fire Code of Canada; 3) Provincial or other Regulations. 1.6 These requirements do not cover: a) Oil burner pumps, which are evaluated in accordance with: 1) In the United States: Requirements defined in the Standard for Pumps for Oil-Burning Appliances, UL 343. 2) In Canada: Requirements defined in the Guide for Investigation of Pumps for Oil-Burning Appliances, ULC/ORD-C343. b) Pumps for engine-powered automotive equipment. c) Pumps for marine use which are evaluated under the Standard for Mechanically and Electrically Operated Fuel Pumps for Marine Use, UL 1130. d) Pumps for use in chemical, petrochemical, or petroleum processing plants; utility power plants; petroleum production facilities; pipeline pump stations; pipeline or marine terminals; or bulk plant distribution and related facilities. e) Pumps used in mobile applications, such as on tank trucks, portable tanks, or portable containers mounted on vehicles. f) Pumps rated more than 600 volts. g) Pump assemblies also provided with a flammable liquid meter or electrically-operated shutoff valve, which are evaluated in accordance with: 1) In the United States: The requirements defined in the 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, UL 87B. 2) In Canada: The requirements defined in the Standard for Power-Operated Dispensing Devices for Flammable Liquids, CSA B346. h) Pumps intended for use with gasoline and gasoline/ethanol blends which are evaluated in accordance with the Standard for Power-Operated Pumps for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 – E85), UL/ULC 79A. 1.7 The pump assembly may be constructed such that it provides for the installation and use of a hose and hose nozzle valve.
