NOTE: Products tested for performance at -40°F(-40℃) only are not marked for lowest operating temperature.Only products testedfor performance at-65°F(-54°C) are marked accordingly.
1.6These requirements also cover fuel hose assemblies designated as “low permeation ", intended foruse on dispensing devices for flammable and combustible liquids.
1.7These requirements do not cover hose or hose assemblies, intended for use in automotive vehiclesor in confined areas, except for locations inside the housings of dispensing devices complying with theStandard for Power-Operated Dispensing Devices for Petroleum Products, UL 87.
