DIN EN 14420-8:2013-09

This European Standard is applicable for hose fittings with symmetrical half couplings (Guillemin system), with mobile locking ring, for hose assemblies with a maximum working pressure of up to 10 bar) with hose tails according to EN 14420-2 and clamp units according to EN 14420-3. Couplings in accordance with this European Standard serve as link between hoses and connections to transport liquids and solids (for instance powders, granules), except for steam and liquid gas. The standard specifies dimensions, types of connections, types of materials, marking requirements and testing requirements. The working temperature is -20 °C up to +65 °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.
