UL 330B
1 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 covered by these requirements are intended for use with one or more of the following fuels:

• a) Diesel fuel and diesel fuel/biodiesel blends with nominal biodiesel concentrations up to 5 percent (B0 - B5) formulated in accordance with the Standard Specification 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 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.

1.3 Hose assemblies are intended for use in accordance with the Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A.

1.4 These requirements cover hose and hose assemblies (hose with couplings attached) in sizes up to and including 1-1/2 inches (38.1 mm).

1.5 Hose for conveying liquid fuel is intended for use at a maximum working pressure of 50 psig (345 kPa).

1.6 These requirements cover hose and hose assemblies for use at temperatures down to minus 40°C (minus 40°F) or optionally down to minus 54°C (minus 65°F).

1.7 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 Outline 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.

1.8 These requirements do not cover hoses or hose assemblies for use with any other fuel other than as described in 1.2.
