Section I - Scope of this Transfeu dissemination
I.1
Scope of the dissemination
TRANSFEU will contribute with this document to the standardization process for high level
European fire safety rules for railways.
The new dynamic test measurement methods for fire effluents and toxic gases,
product classification and common tools for safety design in railway vehicles should be
welcomed by the experts from the JWG fire safety for Railways and by many experts who
are involved in standards writing activities in other areas of surface transportation.
This close liaison will enable possible pre-normative and normative inputs to be introduced
into European standards so that there will be improved fire safety design principles applied to
railways and other surface transportation over the course of project.
I.2
First step, actual document of the Transfeu distribution
Due to the requirements of the European Rail Directives and the associated Technical
Specifications for Interoperability (HS TSI, CR TSI and RST TSI), there is an urgent need to
convert CEN/TS 45545-2 into a full European Norm EN 45545-2 with an improved
classification system for the toxicity of fire effluents generated by products on railway
vehicles.
Since pr EN 45545-2 should be ready for ballot during 2011, the improved continuous gas
measuring and assessment methodology developed in WP2 will be used to establish
performance criteria for products in trains. A new classification system for fire effluents will
then be proposed for incorporation into pr EN 45545-2.
In order to respect this target date this classification system will be developed from first 30
products tested in the WP2.
This changing were not accepted by the JWG during revision for the version of the
FV UAP_Fpr EN 45545-2 which was voted positively on the 7. of November 2013.

Title
Introduction
The measurement of the level of toxic effect of materials and their toxicity
classification is very important but also it is the most difficult to assess in order
to estimate the real evacuation time of passengers in case of fire. In railway
vehicles, the current test method of toxic evaluation and classification of
products (materials) are described in the CEN Technical Specification 455452. However, there is a lack of confidence in the robustness of the existing
product) toxicity classification. Indeed it is based only on static measurement
at two points for a few products, and then extrapolated for others. This means
that this prescriptive products classification can be far from reality. In addition
there is no way to compare different national requirements for toxicity as there
is no harmonisation regarding the measurement method and this prevents the
European industry from adopting common safety rules and consequently
reduces competitiveness. In order to improve fire safety European standards
in railway vehicles and other surface transport a new prescriptive classification
of products based on dynamic measurements of various material toxic effects
is needed.

Title
Validation of the
conventional
classification
system proposed
in the first step
(section I.2)
Introduction
In Deliverable 3.3 and 3.4, as proposed on Step 1, when CIT calculations have
been carried out, the reference gas concentrations used have been the same
as those detailed in CEN/TS 45545-2. These values are based on IDLH
(Immediately Dangerous to Life and Health), which is recognized as a limit for
personal exposure to the gas component by NIOSH (USA National Institute for
Occupational Safety and Health (1997 version).
In Deliverable 6.5, the NIOSH reference gas concentrations have been
replaced by
Concentrations which are expected to seriously compromise the ability of
exposed occupants to escape from a fire in a rail coach. These gas
concentrations are specified in ISO 13571 (2nd Edition, September 2012).
The objective of this deliverable is to validate the conventional pragmatic classification
criteria proposed in WP3 (Step 1) by using data from 70 products and with the help of
fire safety engineering principles developed in WP4, WP5 and WP6.
One-zone modelling of 70 products in single deck and double deck railway
vehicles has been conducted so that a new classification system for the
toxicity of fire gases from products installed on European trains should be
proposed to the
CEN/TC256 & CENELEC/TC9X Joint Working Group which will revise EN
45545-2 (1st Edition) to EN 45545-2 (2nd Edition).
The work has involved the development of new equations to calculate the FED
and FEC of the gaseous effluents from the continuous gas measurements
obtained in the EN ISO 5659-2 smoke chamber using FTIR spectrometry.
The location of these products on various European trains was also
considered so that the conditions for fire tests (especially the ignition models)
may simulate the end-use of the product and hence, the derived classification
criteria can be seen to be relevant to real train environments.
The classification system that has been developed is designed to relate to the
compromised tenability of passengers who need to escape from a coach
where a fire develops.
This methodology is defined in ISO 13571 (2nd Edition).
