ANSI/CAN/UL/ULC 330A:2024

Scope 1.1 These requirements cover hose and hose assemblies, including vapor recovery hose and assemblies, for use on dispensing devices for motor fuels. A flammable liquid hose assembly consists of flexible hose and fittings suitable for attachment to motor fuel dispensing equipment. Motor fuels, as defined by these requirements, include one or more of the fuels described in 1.3. 1.2 Hose and hose assemblies for gasoline/ethanol blends with nominal ethanol concentrations up to 85 percent (E0 – E85) shall be constructed to comply with the following: a) The requirements defined in UL 330, Standard for Hose and Hose Assemblies for Dispensing Flammable and Combustible Liquids, 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 motor fuels: 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 percent 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 Gasoline for Use as Automotive Spark-Ignition Engine Fuel, ASTM D4806; or c) Gasoline/ethanol blends with nominal ethanol concentrations above 25 percent 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. 1.4 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). Hose for conveying fuel vapors is intended for use at a maximum working pressure of 0.5 psig (3.4 kPa), including slight negative pressures from vacuum assist systems. 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 also cover fuel hose assemblies optionally designated as “low permeation.” For the purposes of this Standard, permeation is considered to encompass fuel loss through the flexible hose, fuel loss at the fittings and fuel loss at the connection between the hose assembly and the equipment to which it is intended to be attached in the dispensing system. 1.9 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 Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations Up To 85 Percent (E0 – E85), UL 87A. 1.10 These requirements do not cover hoses or hose assemblies for use with any other fuel other than as described in 1.3. 1.11 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. 1.12 For requirements for hose and hose assemblies for biodiesel fuel, diesel/biodiesel blends with nominal biodiesel concentrations up to 20 % (B20), refer to UL/ULC 330B.
