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 gasoline/ethanol blends with nominal ethanol concentrations up to 85 % (E0 – E85) 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) Gasoline formulated in accordance with the Standard Specification for Automotive Spark-Ignition Fuel, ASTM D4814; b) Gasoline/ethanol blends with nominal ethanol concentrations up to 25 % ethanol (E25), consisting of gasoline formulated in accordance with the Standard Specification for Automotive Spark-Ignition Fuel, ASTM D4814, when blended with denatured fuel ethanol formulated to be consistent with the Standard Specification for Denatured Fuel Ethanol for Blending with Gasolines for Use as Automotive Spark-Ignition Engine Fuel, ASTM D4806; or c) Gasoline/ethanol blends with nominal ethanol concentrations above 25 % formulated in accordance with the Standard Specifications in (b) or formulated in accordance with the Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines, ASTM D5798, as applicable. 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: The requirements defined in the Standard for Pumps for Oil-Burning Appliances, UL 343. 2) In Canada: The 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 Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 – E85), UL 87A. 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 diesel fuel, biodiesel fuel, diesel/biodiesel blends, kerosene, or fuel oil, which are evaluated in accordance with the Standard for Power-Operated Pumps for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil, UL/ULC 79B. 1.7 The pump assembly may be constructed such that it provides for the installation and use of a flammable liquid hose and hose nozzle valve. 1.8 Products intended to be rated for use with gasoline or gasoline/ethanol blends with nominal ethanol concentrations: a) Up to 25 % (E0 – E25) shall be evaluated using the CE25a test fluid as the only applicable test fluid; b) Up to 40 % (E0 – E40) shall be evaluated using both the CE25a and CE40a test fluid; or c) Up to 85 % shall be evaluated using both the CE25a and the CE85a test fluids.
