Introduction
EN 45545-3 has been developed from existing fire safety regulations for railway vehicles from the
International Union of Railways (UIC) and different European countries.
In using the operation and design categories defined in EN 45545-1, the requirements laid down in
this part take into account the current operating conditions for European public rail transport.

1 Scope
This document specifies the fire resistance requirements and testing methods for fire barriers for
railway vehicles.
The objective of the measures and requirements, specified in this document, 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 document. It is not within the scope of this document to describe measures that
ensure the preservation of the railway vehicles in the event of a fire.
