The nominal sizes covered are DN 13 to DN 40. The maximum working pressure is 16 bar and the maximum working temperature is 65 °C. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Hose fittings shall be designed such that they comply with the requirements of this document when attached correctly and establish a frictional and positive-locking tight connection on the hose. Hose fittings shall be designed such that when fitted to hoses the hose is destroyed first before being torn out from the fitting, if overstress occurs. Hose side fitting components shall not cause any dangerous notch or shear stresses on the hose. SIST EN 14424:2005



EN 14424:2004 (E) 5 4.2 Resistance of the fitting materials to the fluid The user and/or the purchaser shall give consideration to the potential hazard caused by the medium and the operating conditions when selecting the type of connection. In individual cases, other concentrations and additions to the medium as well as increase of temperature can reduce the resistance of the metallic materials. In these cases details shall be agreed between purchaser and manufacturer. If data are not available, individual tests are necessary. The fitting components may be surface protected, e.g. nickel-plated, zinc-plated, chrome-plated or polymer coating. Details to be agreed between purchaser and manufacturer. The pairing of fittings from different material groups shall be avoided, if the presence of electrolytes is expected (contact corrosion). 4.3 Maximum working pressures and temperatures All hose fittings shall be capable of operating the working pressure range – 0,8 bar up
