Fire-fighting hoses - Semi-rigid delivery hoses and hose assemblies for pumps and vehicles
EN 1947 specifies the requirements and test methods for semi-rigid hoses for use on fire-fighting vehicles and trailer pumps. The hoses are intended for use at a maximum working pressure of 1,5 MPa for normal pressure hoses (category I) and 4,0 MPa for high pressure hoses (category II). The hoses are further subdivided into types and classes (see Clause 4). This European Standard applies to hoses for fire-fighting purposes intended for use at ambient conditions 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 6.5 and identified by their marking in Clause 8 h). Hoses conforming to this standard are intended for use with fire hose couplings conforming to the relevant national standards for couplings.’ Requirements are also given for hose assemblies (see Clause 9) where these are fitted by the hose manufacturer.
Feuerlöschschläuche - Formstabile Druckschläuche und Einbände für Pumpen und Feuerwehrfahrzeuge
Diese Europäische Norm legt die Anforderungen an und Prüfverfahren für formstabile Haspelschläuche fest, die bei Feuerlöschfahrzeugen und Anhängerpumpen eingesetzt werden. Die Schläuche sind für den Einsatz bei einem maximalen Arbeitsdruck für Normaldruckschläuche (Kategorie I) von 1,5 MPa und 4,0 MPa für Hochdruckschläuche (Kategorie II) vorgesehen. Die Schläuche werden weiter in Typen und Klassen unterteilt (siehe Abschnitt 4).
Die Norm gilt für Druckschläuche für Feuerlöschzwecke, die für einen Einsatz bis zu einer minimalen Umgebungstemperatur von –20 °C vorgesehen sind.
ANMERKUNG 1 Schläuche für den Einsatz bei Temperaturen unter –20 °C können nach Vereinbarung zwischen Hersteller und Auftraggeber geliefert werden.
Der vorliegenden Norm entsprechende Schläuche sollten mit Feuerwehrschlauchkupplungen versehen sein, die den jeweiligen nationalen Normen für Kupplungen entsprechen.
Für Schlaucheinbände sind ebenfalls Anforderungen angegeben (siehe Abschnitt 8), falls diese vom Schlauchhersteller montiert werden.
ANMERKUNG 2 Sämtliche Drücke sind in Megapascal angegeben. 1 MPa = 10 bar.
Tuyaux de lutte contre l'incendie - Tuyaux de refoulement semi-rigides et flexibles pour pompes et véhicules
La présente Norme européenne spécifie les exigences et les méthodes d'essai relatives aux tuyaux semi-rigides installés sur les véhicules de lutte contre l'incendie et sur les motopompes remorquables. Les tuyaux sont destinés à être utilisés à une pression maximale de service de 1,5 MPa pour le service normal (catégorie I) et de 4,0 MPa pour les tuyaux haute pression (catégorie II). Les tuyaux sont ensuite répartis en types et classes (voir Article 4).
La norme s'applique aux tuyaux de refoulement pour la lutte contre l'incendie destinés à être utilisés à une température ambiante minimale de – 20 °C.
NOTE 1 Les tuyaux destinés à une utilisation à des températures inférieures à – 20 °C peuvent être fournis dans le cadre d'un accord entre le fabricant et l'acheteur.
Il convient d'utiliser les tuyaux conformes à la présente norme avec des raccords conformes aux normes nationales pertinentes relatives aux raccords.
Des exigences relatives aux flexibles sont également données (voir Article 8) lorsqu'ils sont montés par le fabricant du tuyau.
NOTE 2 Toutes les pressions sont exprimées en mégapascals. 1 MPa = 10 bar.
Gasilske cevi - Poltoge tlačne cevi, vgrajene k črpalkam in v vozila
Standard EN 1947 določa zahteve in preskusne metode za poltoge cevi, ki se uporabljajo v okviru gasilskih vozil in priklopnih črpalk. Cevi so namenjene uporabi pri najvišjem delovnem tlaku 1,5 MPa za normalne tlačne cevi (kategorija I) in 4,0 MPa za visokotlačne cevi (kategorija II). Cevi se dodatno delijo na tipe in razrede (glej točko 4). Ta evropski standard se uporablja za cevi za gašenje, namenjene uporabi pri okoljskih pogojih znotraj temperaturnega razpona –20 °C do +60 °C. OPOMBA 1: Cevi, ki se uporabljajo pri temperaturah okolja pod –20 °C, se lahko dobavijo, če so bile preskušene pri določeni nižji temperaturi v skladu s točko 6.5 in opredeljene z oznako v točki 8 h). Cevi, ki so skladne s tem standardom, so namenjene uporabi s spojkami za gasilske cevi, ki so v skladu z ustreznimi nacionalnimi standardi za spojke. Zahteve so podane tudi za cevne priključke (glej točko 9), če jih zagotovi proizvajalec cevi.

1 Scope
This European Standard specifies the requirements and test methods for semi-rigid hoses for use on fire-
fighting vehicles and trailer pumps. The hoses are intended for use at a maximum working pressure of
1,5 MPa for normal pressure hoses (category I) and 4,0 MPa for high pressure hoses (category II). The hoses
are further subdivided into types and classes (see Clause 4).
This European Standard applies to hoses for fire-fighting purposes intended for use at ambient conditions
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 6.5 and identified by their marking in Clause 8 h).
Hoses conforming to this standard are intended for use with fire hose couplings conforming to the relevant
national standards for couplings.’
Requirements are also given for hose assemblies (see Clause 9) where these are fitted by the hose
manufacturer.
NOTE 2 All pressures are expressed in megapascals. 1 MPa = 10 bar.
