Fire-fighting hoses - Non-percolating layflat hoses for fixed systems

EN 14540 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 25 mm to 52 mm. This European 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 and a maximum ambient temperature of +60 °C. Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant national standards for couplings.

Feuerlöschschläuche - Flachschläuche für Wandhydranten

Diese Europäische Norm legt die Anforderungen an und Prüfverfahren für durchsickerbeständige Flach-schläuche für Wandhydranten fest. Die Schläuche sind für den Einsatz bei einem maximalen Arbeitsdruck von 1,5 MPa und für Innendurchmesser von 25 mm bis 52 mm vorgesehen.
Die Norm gilt ausschließlich für Schläuche für Feuerlöschzwecke, die für den Einsatz bei einer minimalen Umgebungstemperatur von –20 °C unter normalen Bedingungen und einer minimalen Temperatur von –30 °C bei kälteren klimatischen Bedingungen vorgesehen sind.
Dieser Norm entsprechende Schläuche sollten mit Kupplungen für Feuerlöschschläuche verwendet werden, die den jeweiligen nationalen Normen für Kupplungen entsprechen.
Schläuche für den Einsatz auf Schiffen und/oder in aggressiven Umgebungen zur Verwendung mit Wand-hydranten, wie in EN 671-2 festgelegt, können den Anforderungen dieser Norm entsprechen.
ANMERKUNG   Alle Drücke sind Manometerdrücke und werden in Megapascal angegeben. )

Tuyaux de lutte contre l'incendie - Tuyaux aplatissables étanches pour systèmes fixes

La présente Norme européenne spécifie les exigences et méthodes d'essai applicables aux tuyaux aplatissables étanches prévus pour des systèmes fixes. Ces tuyaux sont destinés à être utilisés à une pression maximale de service de 1,5 MPa et leur diamètre doit être compris entre 25 mm et 52 mm.
La Norme s'applique exclusivement aux tuyaux de lutte contre l'incendie destinés à être utilisés à une température ambiante minimale de -20 °C dans des conditions normales, et à une température minimale de -30 °C dans des conditions climatiques impliquant des températures plus basses.
Il convient que les tuyaux conformes à la présente norme soient utilisés avec des raccords de tuyau de lutte contre l'incendie conformes aux Normes nationales applicables aux raccords.
Si les tuyaux pour applications marines et/ou environnements agressifs doivent être utilisés avec des postes d'eau muraux tels que spécifiés dans l'EN 671-2, ils peuvent satisfaire aux exigences de la présente Norme.
NOTE    Toutes les pressions sont des pressions manométriques et sont exprimées en mégapascals .

Gasilske cevi - Gasilske ploske tlačne cevi za hidrante

Standard EN 14540 določa zahteve in preskusne zahteve za gasilske ploske tlačne cevi za hidrante. Cevi so namenjene uporabi pri najvišjem delovnem tlaku 1,5 MPa pri razponu notranjih premerov med 25 mm in 52 mm. Ta evropski standard se uporablja izključno za cevi za gašenje, namenjene uporabi pri najnižji temperaturi okolja –20 °C v normalnih pogojih in najnižji temperaturi –30 °C v hladnejših podnebnih pogojih ter pri najvišji temperaturi okolja +60 °C. Cevi, ki so skladne s tem standardom, naj bi se uporabljale s spojkami za gasilske cevi, ki so v skladu z ustreznimi nacionalnimi standardi za spojke.

This revised standard now references EN 15889:2011, Fire-fighting hoses - Test methods, which includes the test methods formerly in annexes within EN 14540. This standard is based on liaison with CEN/TC 191 “Fixed fire-fighting systems” and should be read in conjunction with EN 671-2. Requirements for semi-rigid hoses for use with fire-fighting pumps and vehicles are given in EN 1947; those semi-rigid hoses for fixed systems are given in EN 694. 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.

EN 14540:2014 (E) 4 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 with a pressure indicator, a layflat hose with its support and a nozzle. The fixed systems are specified in EN 671-2, Fixed firefighting systems — Hose systems — Part 2: Hose systems with lay-flat hose. SIST EN 14540:2014

EN 14540:2014 (E) 5 1 Scope 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 25 mm to 52 mm. This European 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 and a maximum ambient temperature of +60 °C. Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant national standards for couplings. NOTE 1 eoses 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). 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. NOTE 2 All pressures are gauge pressures and are expressed in megapascals1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
