This European Standard specifies requirements and methods of test for the construction and performance of fire hose systems with lay-flat hose for installation in buildings and other construction works, permanently connected to a water supply, for use by the occupants. Its requirements may apply in general for other applications, for example in marine applications or in aggressive environments, but additional requirements may be necessary in such cases. For convenience of application in conformity testing, the normative annexes of this standard are arranged so that annex A gives the sequence of testing for conformity assessment and annexes B, C, D and E are in the correct sequence for testing. NOTE All pressures are gauge pressures and are expressed in megapascals. 1 MPa = 10 bar.
