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.
The standard applies exclusively to hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 ℃ in normal conditions, and a minimum temperature of -30 ℃ in colder climatic conditions.
Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant
national standards for couplings.
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 All pressures are gauge pressures and are expressed in megapascals.
