Introduction

EN 45545‑4 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 specified in EN 45545‑1:2013, the requirements laid down in this part take into account the current operating conditions for European public rail transport.

1 Scope

This document specifies fire safety requirements for railway vehicle design to cover the objectives specified in EN 45545‑1:2013.

The measures and requirements specified in this document aim to protect passengers and staff in railway vehicles in the event of a fire on board by minimizing the risk of a fire starting, delaying the fire development and controlling the spread of fire products through the railway vehicle, thus aiding evacuation.

It is not within the scope of this document to describe measures which ensure the preservation of the railway vehicles in the event of a fire.
