Hose and Hose Assemblies for Dispensing Flammable and Combustible Liquids
1.1 This Standard sets forth minimum requirements for hose and hose assemblies, including vapor
recovery hose and assemblies, for use on dispensing devices for flammable and combustible liquids. A
hose assembly consists of flexible hose and fittings suitable for attachment to flammable and combustible
liquid dispensing equipment.
1.2 Hose assemblies are intended for use:
a) In the United States, in accordance with the Automotive and Marine Service Station Code of
National Fire Protection Association, NFPA 30A; or
b) In Canada, in accordance with the National Fire Code of Canada.
1.3 These requirements cover hose and hose assemblies (hose with couplings attached) in sizes up to
and including 1-1/2 in (40 mm).
1.4 Hose for conveying liquid fuel is intended for use at a maximum working pressure of 50 psi (350
kPa). Hose for conveying vapors of fuel is intended for use at a maximum working pressure of 0.5 psi (3.5
kPa), including slight negative pressures from vapor assist systems.
1.5 These requirements cover hose and hose assemblies for use at temperatures down to -40° F
(-40°C) or -65°F (-54°C) and up to +125°F (+52°C).
NOTE: Products tested for performance at -40°F(-40°C) only are not marked for lowest operating temperature. Only products tested
for performance at -65°F (-54°C) are marked accordingly.
1.6 These requirements also cover fuel hose assemblies designated as “low permeation”, intended for
use on dispensing devices for flammable and combustible liquids.
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.
1.8 This Standard does not cover hose or hose assemblies for aircraft refueling service.
