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 European Standard have been specified to ensure that hose system can be operated
efficiently by one person and that such systems have a long service life.
1 Scope
This European Standard specifies requirements and methods of test for the construction and performance of
fire hose reel systems with lay-flat hose for installation in buildings, permanently connected to a water supply,
for use by the occupants.
Furthermore, it provides also for requirements on evaluation of conformity and marking of these products.
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.
