| ANOTACE "ČSN EN 14540 (38 9504) This European Standard specifies the requirements and test methods for non-percolating layflat hoses for fixed systems. The hoses are intended for use at a maximum working pressure of 1,5 MPa over a range of inside diameters from 25 mm to 52 mm. This European Standard applies exclusively to hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 st.C in normal conditions, and a minimum temperature of -30 st.C in colder climatic conditions and a maximum ambient temperature of +60 st.C. Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant national standards for couplings. NOTE 1 - Hoses for use at ambient temperatures below -20 st.C can be supplied if they have been tested at the specified lower temperature in accordance with 6.4 and identified by their marking in Clause 8 f). Hoses in marine applications and/or aggressive environments to be used with wall hydrants as specified in EN 671-2 can conform to the requirements of this standard. NOTE 2 - All pressures are gauge pressures and are expressed in megapascals ." | ||
