Fire-fighting hoses - Semi-rigid hoses for fixed systems
This European Standard specifies the requirements and test methods for semi-rigid hoses for fire-fighting purposes for use with fixed systems. The hoses are intended for use at a maximum working pressure of 1,2 MPa for hoses of 19 mm and 25 mm inside diameter and 0,7 MPa for hoses of 33 mm inside diameter.
Hoses conforming to this European Standard are intended for applications where long intervals can occur between the occasions of use, for example on fixed fire hose reels in buildings and other construction works.
This European Standard applies exclusively to hoses for fire-fighting purposes intended for use at ambient conditions in non-aggressive or non-corrosive atmospheres within the temperature range −20 °C to +60 °C.
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 8 f).
NOTE 2 All pressures are expressed in megapascals. 1 MPa = 10 bar

Gasilske cevi - Poltoge cevi za hidrante
Standard EN 694 določa zahteve in preskusne metode za poltoge cevi za gašenje, ki se uporabljajo s hidranti. Cevi so namenjene uporabi pri najvišjem delovnem tlaku 1,2 MPa za cevi z notranjim premerom 19 mm in 25 mm in 0,7 MPa za cevi z notranjim premerom 33 mm. Cevi, ki so skladne s tem evropskim standardom, se uporabljajo, kadar lahko med uporabo minejo daljši intervali, na primer v pritrjenih požarnih cevnih kolutih v stavbah in drugih gradbenih konstrukcijah. Ta evropski standard se uporablja izključno za cevi za gašenje, namenjene uporabi pri okoljskih pogojih v neagresivni ali nekorozivni atmosferi znotraj temperaturnega razpona –20 °C do +60 °C.

Introduction
A fixed system is a manually operated unit installed in a building in order to make it possible for the occupants
to control and extinguish a small fire. The system consists of fixed units mounted on walls or in cabinets
permanently connected to a water supply. The fixed units are composed of a coupling, a valve, a semi-rigid
hose which is water filled or empty fitted on a reel with its support and a nozzle.
The fixed system is specified in EN 671-1, Fixed firefighting systems - Hose systems - Part 1: Hose reels with
semi-rigid hose.
1 Scope
This European Standard specifies the requirements and test methods for semi-rigid hoses for fire-fighting
purposes for use with fixed systems. The hoses are intended for use at a maximum working pressure of
1,2 MPa for hoses of 19 mm and 25 mm inside diameter and 0,7 MPa for hoses of 33 mm inside diameter.
Hoses conforming to this European Standard are intended for applications where long intervals can occur
between the occasions of use, for example on fixed fire hose reels in buildings and other construction works.
This European Standard applies exclusively to hoses for fire-fighting purposes intended for use at ambient
conditions in non-aggressive or non-corrosive atmospheres within the temperature range −20 °C to +60 °C.
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 8 f).
NOTE 2 All pressures are expressed in megapascals. 1 MPa = 10 bar
