CEN/TC 256/WG 1 - Fire safety

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.

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.

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.

This document specifies the assessment of Fire Containment and Control Systems (FCCS) and associated fire detection systems for railway vehicles as an alternative to the fire barriers specified in EN 45545-3.
This document describes:
- assessment of installation and capability of fire detection system;
- assessment of interaction between fire detection system and FCCS;
- application and limitations of assessment process (mock-up or real scale test).
This document considers any additional assessment requirements when vehicle designs which have already been assessed as acceptable to this document are modified, or when new design variants, which have an impact on FCCS, are made which are based on an existing design.
This document is applicable to any railway vehicle, where fire detection systems and/or Fire Control and Containment Systems are used.
This document defines performance requirements and verification and validation requirements for systems whose objective is to detect and control or contain the effect of fire in order to create a protected area within the railway vehicle until passengers and staff can be evacuated from the railway vehicle. It is additionally assumed that the new railway vehicles comply with EN 45545-2 (material properties) and EN 45545-4 (design rules) in order to achieve the safety requirements defined in the EN 45545 series.

This document describes the measurement of the toxicity potential of the products of combustion based on two test methods:
- Method 1: EN ISO 5659-2 Smoke chamber area-based test with Fourier transform infrared spectroscopy (FTIR) gas analysis techniques;
- Method 2: NF X70-100-2 Tubular furnace small mass-based test.
NOTE 1 This document also specifies test equipment and set out the calculation procedures for evaluation of toxicity data.
NOTE 2 This document can be used in addition to others for the determination of toxic gases from devices installed in tunnel.

This document sets out a test protocol to determine the burning behaviour of a rail vehicle seat design using a set of complete seats prepared and tested according to the procedures given in this document. It also sets out a standardized procedure to assess a seat’s potential for vandalization.
This document describes:
-   fire test method;

This part of EN 45545 specifies requirements for flammable liquids and liquefied petroleum gas installations, e. g. for traction, auxiliary power units, heating or cooking, to cover the objectives defined in EN 45545-1. This part is not applicable to technical liquids themselves, e. g. hydraulic liquid and transformer oil, except where guidance is given as to dealing with spillages, leakage and spray generation.
The measures and requirements specified in this European Standard aim to protect passengers and staff in railway vehicles by preventing a fire from occurring and spreading by leakage of flammable liquids or gases.
It is not within the scope of this European Standard to describe measures for flammable gases, other than liquefied petroleum gases (LPGs).
It is not within the scope of this European Standard to describe measures that ensure the preservation of the railway vehicles in the event of a fire.

This Part of EN 45545 specifies the fire safety requirements for electrical equipment on railway vehicles, including that of trolley buses, track guided buses and magnetic levitation vehicles.
The measures and requirements, specified in this European Standard meet the objective of protecting passengers and staff in railway vehicles in the event of a fire on board by:
-   lowering the risk of starting a fire both during operation and as a result of technical defect and/or malfunction of the electrical equipment,
-   ensuring that electrical emergency equipment continues to be functional until evacuation is complete
(see EN 45545-6).

The measures and requirements specified in EN 45545 are intended to protect passengers and staff in railway vehicles in the event of a fire on board.
EN 45545 specifies:
-   fire protection measures for  railway vehicles;
-   verification methods for these measures.
The protection of passengers and staff is essentially based on measures to:
-   prevent fires occurring due to technical faults and due to equipment design or vehicle layout (Part 1, Part 4, Part 5 and Part 7);
-   minimise the possibility of ignition of materials installed on railway vehicles due to accidents or vandalism (Part 1 and Part 2);
-   detect a fire should it occur (Part 6);
-   limit the spread of fire by specification of materials according to their operational categories (Part 2) and by measures for containment (Part 3);
-   minimise the effects of fire in terms of heat, smoke and toxic gases on passengers or staff through the specification of materials installed on railway vehicles (Part 2);
-   control and manage a fire, for example by means of fire detection, suppression and/or emergency shut down (Part 6).
The ultimate objective in the event of a fire on board is to allow passengers and staff to evacuate the railway vehicle and reach a place of safety.
The present European Standard describes the measures to be taken in the design of the vehicles in the context of the infrastructure on which they operate.
It is not within the scope of EN 45545 to describe measures that ensure the preservation of the vehicles in the event of a fire beyond what is required to fulfil the objective to protect passengers and staff.

-   operation categories;
-   design categories;
-   fire safety objectives;
-   general requirements for fire protection measures and their evaluation of conformity.
