(Main)Railway applications - Fire protection on railway vehicles - Part 2: Requirements for fire behaviour of materials and components
Railway applications - Fire protection on railway vehicles - Part 2: Requirements for fire behaviour of materials and components
This part of EN 45545 specifies the reaction to fire performance requirements for materials and products used on railway vehicles as defined in EN 45545-1.
The operation and design categories defined in EN 45545-1 are used to establish hazard levels that are used as the basis of a classification system.
For each hazard level, this part specifies the test methods, test conditions and reaction to fire performance requirements.
It is not within the scope of this European Standard to describe measures that ensure the preservation of the vehicles in the event of a fire.
Bahnanwendungen - Brandschutz in Schienenfahrzeugen - Teil 2: Anforderungen an das Brandverhalten von Materialien und Komponenten
Dieses Dokument legt die Anforderungen an das Brandverhalten von Werkstoffen und Komponenten für Schienenfahrzeuge nach EN 45545 1 fest.
Die Betriebs- und Bauartklassen nach EN 45545 1 werden verwendet, um die Gefährdungsstufen (en: hazard level, HL) zu ermitteln, die als Basis des Klassifizierungssystems genutzt werden.
Für jede Gefährdungsstufe legt dieser Teil die Prüfverfahren, die Prüfbedingungen und die Anforderungen an das Brandverhalten fest.
Maßnahmen, die die Erhaltung der Fahrzeuge im Brandfall sicherstellen, gehören nicht zum Anwendungsbereich dieses Dokuments.
Applications ferroviaires - Protection contre les incendies dans les véhicules ferroviaires - Partie 2 : Exigences du comportement au feu des matériaux et des composants
Ce document spécifie les exigences de performance de réaction au feu pour les matériaux et produits utilisés à bord de véhicules ferroviaires telles que définies dans l’EN 45545-1.
Les catégories d’exploitation et de conception définies dans l’EN 45545-1 sont utilisées pour établir les niveaux de risque servant de base au système de classification.
Pour chaque niveau de risque, cette partie spécifie les méthodes d’essai, les conditions d’essai, et les exigences de performance de réaction au feu.
Il n’est pas dans le champ d’application du présent document de décrire les mesures de protection des véhicules lors d’un incendie.
Železniške naprave - Požarna zaščita na železniških vozilih - 2. del: Zahteve za obnašanje materialov in sestavnih delov v požaru (vključuje dopolnilo A1)
Ta del standarda EN 45545 določa zahteve odziva na ogenj za materiale in proizvode, ki se uporabljajo na železniških vozilih, kot je opisano v standardu EN 45545-1.
Obratovalne in konstrukcijske kategorije, podane v standardu EN 45545-1, se uporabljajo za določanje stopenj tveganja, ki so podlaga za razvrstitev v sistem.
Za vsako stopnjo tveganja so v tem delu specifikacije določene preskusne metode, preskusni pogoji in zahteve odziva na ogenj.
V okviru tega evropskega standarda niso opisani ukrepi, ki zagotavljajo zaščito vozil v primeru požara.
