BS EN 1947:2014EN 1947:2014 (E) 4 Introduction These semi-rigid delivery hoses are used by the fire service

21、 and incorporates those hoses used manually to control and extinguish fires. The hose requires to be fitted with couplings to form a hose assembly which is fitted onto reels on fire fighting vehicles. BS EN 1947:2014EN 1947:2014 (E) 5 1 Scope This European Standard specifies the requirements and tes

22、t 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 classe

23、s (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

24、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

25、 the hose manufacturer.
