patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document includes Amendment 1 approved by CEN on 21 November 2022.
This document will supersede EN 15437-2:2012.
The start and finish of text introduced or altered by amendment is indicated in the text by tags !".
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral
part of this document.
EN 15437 "Railway applications - Axlebox condition monitoring - Interface and design requirements” is
comprised of the following parts:

— Part 2: Performance and design requirements of on-board systems for temperature monitoring (the
present document).
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

Introduction
Failed wheelset bearings on rolling stock create a hazard to the safe operation of the railway. If a
bearing fails while rolling stock is in service there is the potential for a catastrophic event. A
catastrophic event may result in fatalities, severe damage to rolling stock and/or the infrastructure and
a risk that rolling stock may derail and/or a fire may develop.
One indication that a bearing is about to fail is a rise in the heat generated by the bearing. Bearings that
are about to fail may, therefore, be detected by monitoring their temperature to identify an
unacceptable rise.
This part of EN 15437 covers the monitoring of axlebox bearing temperature by on-board monitoring
systems. According to the application, these may be considered to be basic systems or advanced
systems.
In most cases, rolling stock axleboxes continue to be monitored by trackside Hot AxleBox Detectors
[HABD] which is the subject of Part 1 of EN 15437. The monitoring system is fitted on the rolling stock
and is able to function autonomously from trackside monitoring systems which are ground-based.
In contrast to trackside monitoring systems, the detection characteristic may be adapted to the
particular vehicle design, such that the alarm levels employed are configured depending on the bearing
properties, sensor arrangement, vehicle type, network characteristics, etc.
The use of on-board monitoring may also provide a solution for overcoming constraints related to bogie
design or other aspects of vehicle design or operation which may prevent effective monitoring by
means of the track-side monitoring systems.
Other devices which apply functionally equivalent alternatives (for example based on the principle of
vibration monitoring) may be available and normalized elsewhere, such as in other parts of this series
of European Standards.
1 Scope
This European Standard defines the minimum performance requirements of on-board monitoring
systems for axlebox condition monitoring by means of temperature measurements.
This European Standard refers to temperature monitoring of the axlebox. However, the design may be
such that the rolling bearing itself is monitored directly.
The requirements of this European Standard are intended to apply equally to basic monitoring systems
for monitoring the axlebox temperature through to more technically complex systems that may employ
a combination of mechatronics.
To ensure the compatibility of monitoring systems and the effective monitoring functions, this
European Standard defines the requirements in the following areas:
— equipment and characteristics;
— monitoring performance;
— operation and interface.
This part of EN 15437 does not include:
— systems that do not give an indication to the driver;
— how an on-board monitoring system is structured and how it measures the temperature and
identifies axlebox position. This is considered part of equipment design and not part of the
functional requirements set out in this standard;
— operational requirements for acting on the information reported by the on-board monitoring
system;
— operational requirements for conflict of information between trackside monitoring systems and on-
board monitoring systems;
— maintenance requirements for on-board temperature monitoring systems.
