EN 1360:2005 (E) 5 1 Scope This European Standard specifies minimum requirements for three types of hoses in two
24、 categories and two classes of hose assemblies used for measured fuel dispensing, including oxygenated fuels (up to a maximum of 15 % oxygenated compounds). The assemblies are intended for use at ambient temperatures between 30 C and +55 C for normal temperature class and 40 C and +55 C for low temp

34、el and weather-resistant rubber or TPE cover. Hose assemblies shall be capable of conducting an electrical charge from coupling to coupling. When this capability is provided by means of metallic bonding wires, not less than two (metallic) bonding wires shall be embedded in the hose and the metal use
