European foreword
This document (CEN/TR 17532:2020) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been developed in addition to EN 45545 series and EN 50553 to define an assessment
method for Fire Containment and Control Systems (FCCS) that may be installed in rolling stock as an
alternative to full cross-section partitions. The EN 45545-3 requirements are that full cross-section
partitions are required at a maximum separation of 30 metres within a train and each barrier is required
to achieve 15 minutes minimum Fire Resistance – Integrity and Insulation performance. This document
describes an alternative protection system - FCCS - that also protects passengers and staff from the effects
of fire until the train has been evacuated.
It is expected that the FCCS will be activated shortly after a fire that has ignited in a train has been
detected. At the same time, passengers and staff in the affected area may move to a non-affected area of
the train.
This document also defines requirements for the fire detection systems that activate FCCS systems on
board trains.
This document gives the last version of WI947 and comments of NSBs where the compromise is not
finalised.
This document provides information to ERA to close the open point.
This document contains information on research to be done to improve the state of the art. The cost of
the research should be also evaluated.
This document proposes the next steps with the goal of creating a standard that resolves the issues at
hand. This document does not give a cost-benefit-analysis, because such an analysis is not the task of
CEN/TC 256/WG 01 experts.
1 Scope
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 the installation and capability of fire detection systems;
— assessment of the interaction between fire detection systems and FCCS;
— application and limitations of the assessment process (mock-up or real scale test).
This document considers any additional assessment requirements when vehicle designs that 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 the railway vehicle can be cleared of passengers and staff by way of
evacuation. 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.

3.1
fire containment
action of keeping the effects of fire in terms of heat, smoke and toxic gases within prescribed limits based
on avoiding critical thresholds for temperature rise, smoke and toxic gas flow
3.2
fire control
reduction of the effects of a fire to defined levels
Note 1 to entry: It is intended to have no significant risk of serious injury or threat to life.
3.3
detection time
time interval between ignition of a fire and its detection by an automatic or manual system
3.4
affected area
area where the fire should be contained and controlled by FCCS in the context of a fire incident
3.5
non-affected area
area outside the affected area on board of the rolling stock where passengers and staff are protected by
FCCS in the context of a fire incident
Note 1 to entry: This is also called protected area.
3.6
artificial smoke
artificial particulate matter to simulate smoke
3.7
basic module
part of the coach with one or several FCCS devices expected to contain and
