Fire-fighting hoses - Semi-rigid hoses for fixed systems
This European standard specifies the requirements and the tests methods for semi-rigid reel 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 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.
Feuerlöschschläuche - Formstabile Schläuche für Wandhydranten
Anwendungsbereich
In dieser Europäischen Norm werden die Anforderungen und Prüfverfahren für formstabile Haspel-schläuche,
die an Wandhydranten angeschlossen sind und zu Feuerlöschzwecken eingesetzt werden,
festgelegt. Schläuche mit einem Innendurchmesser von 19 mm und 25 mm sind für einen maximalen
Arbeitsdruck von 1,2 MPa, Schläuche mit einem Innendurchmesser von 33 mm für einen maximalen
Arbeitsdruck von 0,7 MPa vorgesehen.
Schläuche, die die Anforderungen dieser Norm erfüllen, sind für Verwendungen vorgesehen, bei denen
lange Zeiträume zwischen den einzelnen Gebrauchsfällen liegen können, z. B. auf fest installierten
Schlauchhaspeln in Gebäuden oder anderen baulichen Anlagen.
Die Norm gilt ausschließlich für Feuerlöschschläuche zur Brandbekämpfung, die für einen Einsatz bei
Umgebungsbedingungen in nicht-aggressiven und nicht-korrosiven Atmosphären innerhalb des
Temperaturbereichs von -20 °C bis +60 °C vorgesehen sind.
ANMERKUNG 1 Schläuche für die Verwendung bei Temperaturen unter -20 °C dürfen auf Kundenanfrage geliefert
werden.
ANMERKUNG 2 Sämtliche Drücke werden in Megapascal angegeben. 1 MPa = 10 bar.
Tuyaux de lutte contre l'incendie - Tuyaux semi-rigides pour systemes fixes
1 Domaine d'application
La présente Norme européenne spécifie les exigences et méthodes d'essai s'appliquant aux tuyaux semi-rigides de lutte contre l'incendie prévus pour des systemes fixes. Les tuyaux sont prévus pour etre utilisés sous une pression maximale de service de 1,2 MPa pour les diametres intérieurs 19 mm et 25 mm et de 0,7 MPa pour le diametre intérieur 33 mm.
Les tuyaux conformes a la présente norme sont destinés a des applications ou il peut s'écouler de longues périodes entre deux utilisations, par exemple sur robinets d'incendie armés dans les bâtiments et autres constructions.
La présente Norme concerne uniquement les tuyaux de lutte contre l'incendie prévus pour etre utilisés dans les conditions ambiantes - atmospheres agressives ou corrosives exclues - dans une plage de température comprise entre - 20 °C et + 60 °C.
NOTE 1 Des tuyaux pour utilisation a des température inférieure a - 20 °C peuvent etre fournis sur demande de l'acheteur.
NOTE 2 Toutes les pressions sont exprimées en mégapascals : 1 MPa = 10 bars.

Page 3EN 694:2001ForewordThis European Standard has been prepared by Technical Committee CEN/TC 192 "Fire serviceequipment", the secretariat of which is held by BSI.This European Standard shall be given the status of a national standard, either by publication of anidentical text or by endorsement, at the latest by November 2001, and conflicting national standardsshall be withdrawn at the latest by November 2001.The standard is based on recommendations from CEN/TC 191 “Fixed fire-fighting systems” andshould be read in conjunction with EN 671-1.At present there is no existing ISO Standard on the same subject but ISO 4642:1978 “Rubberproducts - Hoses, non-collapsible, for fire-fighting service” is under revision by ISO/TC 45.Requirements for semi-rigid hoses for use with fire-fighting pumps and vehicles are given in EN 1947;those for non-percolating layflat hoses are given in EN 1924-1 (pumps and vehicles) and EN 1924-2(fixed systems).Recommendations on the frequency at which tests specified in this standard should be carried out aregiven in annex E.Users of this European Standard are advised to consider the desirability of independent certificationof product conformity with this European Standard based on testing and continuing surveillance,which may be coupled with assessment of a supplier’s quality system against EN ISO 9001.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, CzechRepublic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg,Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
Page 4EN 694:2001IntroductionA fixed system is a manually operated unit installed in a building in order to make it possible for theoccupants to control and extinguish a small fire. The system consists of fixed units mounted on wallsor in cabinets permanently connected to a water supply. The fixed units are composed of a coupling,a valve, a semi-rigid water filled hose with its support and a nozzle.

Each hose type shall be furtherdivided 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:a) a seamless rubber or plastics lining;b) a circular woven textile reinforcement with a rigid spiral helix;c) 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 theconstruction in accordance with Table 1.
