Guidelines for the use of EN 45545-2 for Ni-Cd batteries on board rolling stock

The scope of this document is to guide users of the EN 45545 series, particularly EN 45545 2:2013+A1:2015 and EN 45545 5:2013+A1:2015, in the application of these standards in designing and assessing NiCd batteries on board trains for their fire protection measures. The scope of this document excludes any new requirements, considering only the requirements stated by the above listed standards. However, EN 45545 being generic requirements and not specifically referring to NiCd batteries, this guide helps the application for those batteries.

European Foreword
This document (CLC/TR 50718:2021) has been prepared by CLC/TC 9X “Electrical and electronic applications
for railways”.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
Introduction
The design, verification and testing of Ni-Cd batteries on board rolling stock is standardized by EN 50547, which
refers to the EN 45545 series and particularly to EN 45545-2:2013+A1:2015 in the clause “Fire behaviour
requirements”.
However, the referred series deals with the Ni-Cd batteries in a generic and limited way:
— EN 45545-2:2013+A1:2015 deals with Ni-Cd batteries as a non-listed products.
As a consequence, the application of the EN 45545 series to the case of Ni-Cd batteries on board of trains
opens the door to very different interpretations.
Designers, assessors, producers and customers have very different points of view which could result in
problematic aspects which are difficult to be fixed and agreed upon.
In order to overcome such situations, TC9X decided to set up the Survey Group CLC TC9X WG31 with the task
to prepare a new standard; the SG31 proposes in the meantime to issue guidelines for the application of the
EN 45545 series in case of Ni-Cd batteries on board rolling stock.
This document has been prepared according to the decision 58/12 taken during the TC9X Plenary meeting and
the following approved NWIP, see document BT166/DG11706/DL.
This document is a report of the available experience and best practice in applying the EN 45545 series to the
case of Ni-Cd batteries on board rolling stock.
1 Scope
The scope of this document is to guide users of the EN 45545 series, particularly EN 45545-2:2013+A1:2015
and EN 45545-5:2013+A1:2015, in the application of these standards in designing and assessing Ni-Cd
batteries on board trains for their fire protection measures.
The scope of this document excludes any new requirements, considering only the requirements stated by the
above listed standards.
