ANSI/CAN/UL/ULC 330B:2024

Scope 1.1 These requirements cover hose and hose assemblies for use on dispensing devices for fuels. A flammable liquid hose assembly consists of flexible hose and fittings suitable for attachment to fuel dispensing equipment. Fuels, as defined by these requirements, include one or more of the fuels described in 1.2. 1.2 Hose and hose assemblies for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil shall be constructed to comply with the following: a) The requirements defined in the Standard for Hose and Hose Assemblies for Dispensing Flammable and Combustible Liquids, UL 330, and b) The requirements in this Standard. 1.3 Hose and hose assemblies covered by these requirements are intended for use with one or more of the following fuels: a) Diesel fuel, which includes renewable diesel, and diesel fuel/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 and renewable diesel/biodiesel blends with nominal biodiesel concentrations above 5 percent 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. 1.4 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; b) In Canada: 1) The National Fire Code of Canada; 2) Provincial or other Regulations. 1.5 These requirements cover hose and hose assemblies (hose with couplings attached) in sizes up to and including 1.5 inches (38.1 mm). 1.6 Hose for conveying liquid fuel is intended for use at a maximum working pressure of 50 psig (345 kPa). 1.7 These requirements cover hose and hose assemblies for use at temperatures down to –40 °F (–40 °C) or optionally down to –65 °F (–54 °C). 1.8 These requirements do not cover hose or hose assemblies, intended for use in automotive vehicles or in confined areas, except for locations inside the housings of dispensing devices complying with 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. 1.9 These requirements do not cover hoses or hose assemblies for use with any other fuel other than as described in 1.2. 1.10 For requirements for Hose and Hose Assemblies for Use With Dispensing Devices Dispensing Gasoline and Gasoline/Ethanol Blends With Nominal Ethanol Concentrations Up To 85 Percent (E0 – E85), refer to UL 330A.
