DIN EN 14424:2013-09

This European Standard specifies the design, materials and dimensions of hose fittings with screwed ferrules for rubber and thermoplastic hoses for use with flammable and non-flammable liquids or gases, for instance fuel dispensing hoses, liquid natural gas (LPG) hoses, tank truck hoses and hoses for liquid and gaseous chemicals. It is applicable for nominal sizes DN 13 to DN 40. Up to DN 25 the maximum working pressure is 25 bar, 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. This standard has been prepared by Technical Committee CEN/TC 218 "Rubber and plastics hoses and hose assemblies", the secretariat of which is held by BSI (Great Britain). Regarding the German collaboration Working Committee NA 082-00-02 AA "Schlauchkupplungen" ("Hose couplings") at the Piping and Boiler Plant Standards Committee (NARD) is responsible.
