This European Standard specifies the design, materials and dimensions of hose fittings with screwed ferrules for rubber and thermoplastics hoses for use with flammable and non-flammable liquids or gases, e. g. fuel dispensing hoses, liquid natural gas (LPG) hoses, tank truck hoses and hoses for liquid and gaseous chemicals. The nominal sizes covered are DN 13 to DN 40. Up to DN 25, the maximum working pressure is 25 bar1), and for DN 32 and DN 40 the maximum working pressure is 16 bar. The working temperature range is -20 °C to +65 °C, for LPG-usage it is -30 °C to +70 °C up to DN 25, and for LT-(low temperature) usage it is -50 °C to +70 °C.
