CEN/TC 218/WG 5 - Couplings and hose fittings

This European Standard specifies the design, materials and dimensions of fittings for clamp type coupling assemblies for use with nominal sizes DN 15 to DN 50 steam and hot water hoses. It covers assemblies up to a maximum working pressure of 18 bar ) (corresponding to a saturated steam temperature of 210 °C).

This European Standard specifies dimensions, types of connections, quality of materials, marking requirements and testing requirements 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 bar1) with hose tails according to EN 14420-2 and clamp units according to EN 14420-3. Couplings in accordance with this document serve as link between hoses and connections to transport liquids, solids (e.g. powders, granules) except steam and liquid gas. The working temperature range is -20 °C up to +65 °C. With the Amendment 1 a cross-reference will be added regarding the permissible working pressures and temperature stated in EN 14420-1, 4.3. Furthermore, Figure 1 will be updated.
