Omfang

This European Standard specifies the requirements and test methods for semi-rigid hoses for use on fire-fighting vehicles and trailer pumps. The hoses are intended for use at a maximum working pressure of 1,5 MPa for normal pressure hoses (category I) and 4,0 MPa for high pressure hoses (category II). The hoses are further subdivided into types and classes (see Clause 4). This European Standard applies to hoses for fire-fighting purposes intended for use at ambient conditions within the temperature range −20 °C to +60 °C. NOTE 1 Hoses for use at ambient temperatures below −20 °C can be supplied if they have been tested at the specified lower temperature in accordance with 6.5 and identified by their marking in Clause 8 h). Hoses conforming to this standard are intended for use with fire hose couplings conforming to the relevant national standards for couplings.’ Requirements are also given for hose assemblies (see Clause 9) where these are fitted by the hose manufacturer. NOTE 2 All pressures are expressed in megapascals. 1 MPa = 10 bar.
