EN 14420-4:2013 (E) 5 1 Scope This European Standard specifies requirements for hose tails according to EN 14420-2, with flanges of mating dimensions PN 10/PN 16/PN 25/PN 40 (according to nominal size and pressure stage) according to EN 1092-1, on hose fittings with clamp units according to EN 14420-3. Maximum working pressure is 25 bar1); maximum working temperature is 65 °C. Additionally, flanges are also usable according to EN 14422. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
