1 Scope
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 °C in normal conditions, and a minimum
temperature of −30 °C in colder climatic conditions and a maximum ambient temperature
of +60 °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 °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 8f).
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 megapascals1.
