Fire-fighting hoses - Non-percolating layflat hoses for fixed systems
This European Standard specifies the requirements and test methods for non-percolating layflat hoses for fixed systems. The hoses are intended for use at a maximum working pressure of 1,5 MPa over a range of inside diameters from 15 mm to 52 mm.
The standard applies exclusively to hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 °C in normal conditions, and a minimum temperature of -30 °C in colder climatic conditions.
Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant national standards for couplings.
Hoses in marine applications and/or aggressive environments to be used with wall hydrants as specified in EN 671-2 can conform to the requirements of this Standard or prEN 1924, but prEN 1924 is preferred in these applications.
NOTE All pressures are gauge pressures and are expressed in megapascals .
Feuerlöschläuche - Druckschlauche für Wandhydranten
Diese Europäische Norm legt die Anforderungen und Prüfverfahren für Druckschläuche für Wandhydranten fest. Die Schläuche sind für den Einsatz bei einem maximalen Arbeitsdruck von 1,5 MPa und für Innendurchmesser von 15 mm bis 52 mm vorgesehen.
Die Norm gilt ausschließlich für Schläuche für Feuerlöschzwecke, die für den Einsatz bei einer niedrigsten Temperatur von -20 °C unter normalen Bedingungen und einer niedrigsten Temperatur von -30 °C bei kälteren klimatischen Bedingungen vorgesehen sind.
Schläuche, die dieser Norm entsprechen, sollten mit Feuerlöschschlauchkupplungen verwendet werden, die den jeweiligen nationalen Normen für Kupplungen entsprechen.
Schläuche für den Einsatz auf Schiffen und/oder in aggressiven Umgebungen bei Verwendung in Wandhydranten nach EN 671-2 können entweder den Anforderungen dieser Norm oder von prEN 1924 entsprechen, jedoch ist prEN 1924 bei diesen Anwendungen vorzuziehen.
ANMERKUNG Alle Drücke sind Manometerdrücke und werden in Megapascal angegeben. )
Tuyaux de lutte contre l'incendie - Tuyaux aplatissables étanches pour systemes fixes
La présente Norme européenne spécifie les prescriptions et méthodes d'essai relatives aux tuyaux aplatissables étanches pour systemes fixes. Ces tuyaux sont destinés a etre utilisés a une pression maximale de 1,5 MPa et dans une plage de diametres comprise entre 15 mm et 52 mm.
La norme s'applique exclusivement aux tuyaux de lutte contre l'incendie destinés a etre utilisés a une température minimale de - 20 °C dans des conditions normales, et a une température minimale de - 30 °C dans des conditions climatiques plus froides.
Il convient que les tuyaux conformes a la présente norme soient utilisés avec des raccords type incendie conformes aux normes nationales relatives a ces raccords.
Si les tuyaux pour applications marines et/ou environnements agressifs doivent etre utilisés avec des postes d'eau muraux tels que spécifiés dans l'EN 671-2, ils peuvent etre conformes aux prescriptions énoncées dans la présente norme ou le prEN 1924, le prEN 1924 étant le plus approprié pour ces applications.

EN 14540:2004 (E)4IntroductionA 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 with a pressure indicator, a layflat water filled hose with its support and a nozzle.
EN 14540:2004 (E)51 ScopeThis European Standard specifies the requirements and test methods for non-percolating layflathoses for fixed systems.
