  • SCOPE

    1 Scope

    1.1 These requirements cover hose and hose assemblies, including vapor recovery hose and assemblies, for use on dispensing devices for flammable liquids. A flammable liquid hose assembly consists of flexible hose and fittings suitable for attachment to flammable liquid dispensing equipment. For the purpose of this Standard flammable liquids are gasoline and diesel fuel. The term “gasoline” includes gasoline with small amounts of additives such as detergents, solvents for detergents, and anti-icing chemicals and gasoline with up to 10 percent ethanol.

    1.2 Hose assemblies are intended for use in accordance with the Automotive and Marine Service Station Code of National Fire Protection Association, NFPA 30A.

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

    1.4 Hose for conveying liquid fuel is intended for use at a maximum working pressure of 50 psig (345 kPa). Hose for conveying vapors of fuel is intended for use at a maximum working pressure of 0.5 psig (3.4 kPa), including slight negative pressures from vapor assist systems.

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

    1.6 These requirements also cover fuel hose assemblies designated as “low permeation”, intended for use on dispensing devices for flammable liquids. 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.

    1.7 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 Standard For Power-Operated Dispensing Devices For Petroleum Products, UL 87.
