Introduction
Fire hose systems in proper condition provide a very effective firefighting facility with a continuous supply of water
available immediately.
The requirements of this standard have been framed to ensure that hose reels can be operated efficiently by one
person and that such systems will have a long service life and will not need excessive maintenance.
1 Scope
This European Standard specifies requirements and methods of test for the construction and performance of fire
hose reel systems with semi-rigid 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.
This standard is applicable to both manual and automatic fire hose reels for installation with and without cabinets.
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, E and F are in the correct
sequence for testing.
NOTE All pressures are gauge pressures and are expressed in megapascals. 1 MPa = 10 bar.
