Foreword
This document (EN 694:2014) has been prepared by Technical Committee CEN/TC 192 “Fire and Rescue
Service Equipment”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by January 2015 and conflicting national standards shall be withdrawn at
the latest by January 2015.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 694:2001+A1:2007.
This revised standard now references EN 15889:2011, Fire-fighting hoses - Test methods, which includes the
test methods formerly in annexes within EN 694.
The standard is based on liaison with CEN/TC 191 “Fixed fire-fighting systems” and should be read in
conjunction with EN 671-1.
Requirements for semi-rigid hoses for use with fire-fighting pumps and vehicles are given in EN 1947; those
for non-percolating layflat hoses for fixed systems are given in EN 14540.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
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

3 Terms and Definitions
For the purposes of this standard the following definition applies, together with those for working pressure,
proof pressure and burst pressure given in EN ISO 8330.

semi-rigid hose
hose which maintains its round cross-section even when unpressurized
4 Classification
4.1 General
All types and classes of hoses shall be so flexible that they can be rolled and kept on a drum of minimum
diameter 200 mm for 19 mm and 25 mm inside diameter hose and of minimum diameter 280 mm for 33 mm
inside diameter hose.
Hoses shall be one of two types distinguished by their construction. Each hose type shall be further divided
into classes distinguished by the materials used for lining and cover.
4.2 Classification by types (hose construction)
Type A hoses shall consist of:
a) a seamless rubber or plastics lining;
b) a textile reinforcement with or without a rigid spiral helix;
c) a rubber or plastics cover.
Type B hoses shall consist of:
d) a seamless rubber or plastics lining;
e) a circular woven textile reinforcement with a rigid spiral helix;
f) an uncovered or rubber or plastics cover.
4.3 Classification by class (materials for lining and cover)
The hose types shall be further subdivided into six classes dependent on the materials used in the
construction in accordance with Table 1.
