Railway applications - Fire protection on railway vehicles - Part 3: Fire resistance requirements for fire barriers

This part of EN 45545 specifies the fire resistance requirements and testing methods for fire barriers for railway vehicles.
The objective of the measures and requirements, specified in this part of EN 45545, is to protect passengers and staff in railway vehicles in the event of a developing fire on board.
Use of a Fire Containment and Control System, where permitted as an alternative to a fire barrier, is not in the scope of this part of EN 45545. It is not within the scope of this part of EN 45545 to describe measures that ensure the preservation of the railway vehicles in the event of a fire.

Bahnanwendungen - Brandschutz in Schienenfahrzeugen - Teil 3: Feuerwiderstand von Feuerschutzabschlüssen

Dieses Dokument legt die Feuerwiderstände und Prüfverfahren für Feuerschutzabschlüsse von Schienenfahrzeugen fest.
Der Zweck der Maßnahmen und Anforderungen, die in diesem Dokument festgelegt sind, ist es, Fahrgäste und Personal in Schienenfahrzeugen im Falle, dass sich im Fahrzeug ein Brand entwickelt, zu schützen.
Die Verwendung eines Systems zur Eindämmung und Bekämpfung von Bränden, wo es als Alternative zu Feuerschutzabschlüssen zulässig ist, gehört nicht zum Anwendungsbereich dieses Dokuments. Maßnahmen, die die Erhaltung der Fahrzeuge im Brandfall sicherstellen, gehören nicht zum Anwendungs-bereich dieses Dokuments.

Applications ferroviaires - Protection contre les incendies dans les véhicules ferroviaires - Partie 3: Exigences de résistance au feu des barrières au feu

Le présent document spécifie les exigences de résistance au feu ainsi que les méthodes d'essai applicables aux barrières au feu des véhicules ferroviaires.
Les mesures et exigences spécifiées dans le présent document ont pour objectif d'assurer la protection des voyageurs et du personnel de bord dans les véhicules ferroviaires en cas de développement d'un incendie à bord.
Le présent document ne couvre pas l'utilisation d'un système de lutte et de contrôle des incendies lorsqu'il est autorisé comme solution alternative à une barrière coupe-feu. Le présent document n'a pas vocation à décrire les mesures de protection des véhicules ferroviaires en cas d'incendie.

4 Application of fire barriers
Railway vehicles shall be equipped with fire barriers at the locations specified in Table 1.
5 Classification, requirements and test procedures
5.1 General requirements
The use of the following parameters shall be in accordance with the principles described in
EN 13501-2 integrity criterion E, insulation criterion I and radiation criterion W.
5.2 Classification of fire barriers
Fire barriers shall have fire resistance properties verified by:
— a fire resistance test based on the principles of EN 1363-1; or
— assessment based on fire resistance testing.
Fire barriers shall have performance based on the three parameters (E, W, I) as specified in Table 1.
NOTE For example E30, I15, means integrity is maintained for 30 min and insulation is maintained for
15 min.
5.3 Arc barrier Type A
Type A arc barriers in accordance with EN 45545-5 shall satisfy the requirements for an E15 fire
barrier.
5.4 Arc barrier Type B
Type B arc barriers in accordance with EN 45545-5 shall satisfy the requirements for an E60 fire
barrier.
5.5 Requirements
The requirements for fire barriers depend upon the operation and design categories and their location
in the railway vehicle.
The fire barriers shall be located as specified in Table 1. Examples of the barriers in Table 1 are
described in Annex B.
All vertical fire barriers in the cross section of a railway vehicle shall cover the entire area between the
structural floor and the structural roof. In this context, the middle floor of a double decked vehicle shall
be considered as a floor for the upper deck and as a roof for the lower deck. Where a vertical barrier
reaches the side wall, it shall be extended to the body shell.
Closing devices for ventilation ducts shall conform to the following requirements:
a) where a ventilation duct passes through a fire barrier, the duct shall have a closing device where
it passes through the barrier unless the complete duct meets the same level of fire resistance
requirements as the barrier for:
— its entire length,
— its length to the next fire barrier, the next closing device, or to the exterior of the vehicle.
b) closing devices shall meet the same fire resistance requirements as fire barriers;
c) closing devices shall operate on reaction to a fire.
