applications — Energy measurement on board trains:
Part 1, General;
Part 2, Energy measuring;
Part 3, Data handling;
Part 4, Communication;
Part 5, Conformity assessment.
This series of European Standards follows the functional guidelines description in Annex A “Principles of
conformity assessment” of EN ISO/IEC 17000 tailored to the Energy Measurement System (EMS).
The requirements for Energy Measurement Systems in the relevant Technical Specifications for
Interoperability are supported by this series of European Standards.

- 5 - EN 50463-5:2012
Introduction
The Energy Measurement System provides measurement and data suitable for billing and may also be used
for energy management, e.g. energy saving.
This series of European Standards uses the functional approach to describe the Energy Measurement
System. These functions are implemented in one or more physical devices. The user of this Series of
standards is free to choose the physical implementation arrangements.
Structure and main contents of EN 50463
This series of European Standards is divided into five parts. The titles and brief descriptions of each part are
given below:
EN 50463-1 – General
The scope of EN 50463-1 is the Energy Measurement System (EMS).
EN 50463-1 provides system level requirements for the complete EMS and common requirements for all
devices implementing one or more functions of the EMS.
EN 50463-2 – Energy measuring
The scope of EN 50463-2 is the Energy Measurement Function (EMF).
The EMF provides measurement of the consumed and regenerated active energy of a traction unit. If the
traction unit is designed for use on a.c. traction supply systems, the EMF also provides measurement of
reactive energy. The EMF provides the measured quantities via an interface to the Data Handling System.
The EMF consists of the three functions: Voltage Measurement Function, Current Measurement Function
and Energy Calculation Function. For each of these functions, accuracy classes are specified and
associated reference conditions are defined. This part also defines all specific requirements for all functions
of the EMF.
The Voltage Measurement Function measures the voltage of the Contact Line system and the Current
Measurement Function measures the current taken from and returned to the Contact Line system. These
functions provide signal inputs to the Energy Calculation Function.
The Energy Calculation Function inputs the signals from the Current and Voltage Measurement Functions
and calculates a set of values representing the consumed and regenerated energies. These values are
transferred to the Data Handling System and are used in the creation of Compiled Energy Billing Data.
The standard has been developed taking into account that in some applications the EMF may be subjected
to legal metrological control. All relevant metrological aspects are covered in this part of EN 50463.
EN 50463-2 also defines the conformity assessment of the EMF.
EN 50463-3 – Data handling
The scope of EN 50463-3 is the Data Handling System (DHS).
The on board DHS receives, produces and stores data, ready for transmission to any authorised receiver of
data on board or on ground. The main goal of the DHS is to produce Compiled Energy Billing Data and
transfer it to an on ground Data Collection Service (DCS). The DHS can support other functionality on board
or on ground with data, as long as this does not conflict with the main goal.

EN 50463-3 also defines the conformity assessment of the DHS.
EN 50463-4 – Communication
The scope of EN 50463-4 is the communication services.
This part of EN 50463 gives requirements and guidance regarding the data communication between the
functions implemented within EMS as well as between such functions and other on board units where data
are exchanged using a communications protocol stack over a dedicated physical interface or a shared
network.
It includes the on board to ground communication service and covers the requirements necessary to support
data transfer between DHS and DCS.
EN 50463-4 also defines the conformity assessment of the communications services.
EN 50463-5 – Conformity assessment
The scope of EN 50463-5 is the conformity assessment procedures for the EMS.
EN 50463-5 also covers re-verification procedures and conformity assessment in the event of the
replacement of a device of the EMS.
EMS functional structure and dataflow
Figure 1 illustrates the functional structure of the EMS, the main sub-functions and the structure of the
dataflow and is informative only. Only the main interfaces required by this standard are displayed by arrows.
Because the communication function is distributed throughout the EMS, it has been omitted for clarity. Not all
interfaces are shown.

1 Scope
This European Standard specifies the conformity assessment arrangements for newly manufactured EMS
installed on a traction unit. This includes the integration conformity assessment and installation conformity
assessment. In addition, this document also specifies the conformity assessment procedures for device and
ancillary component replacement (e.g. due to damage in service), and periodic check to verify the EMS
conformity assessment remains valid.
This European Standard does not include elements related to conformity assessment aspects other than
design review and testing provisions for the products, processes or services specified. Consequently, this
part does not delete, change or interpret the general requirements for conformity assessment procedures
and vocabulary detailed in EN/ISO/IEC 17000.
This European Standard does not cover the conformity assessment schemes that, according to CENELEC
Internal Regulations, are the responsibility of ISO policy committee “Committee on conformity assessment”
(ISO/CASCO).

4 Conformity assessment approach
4.1 General
This clause specifies the structure and methodology for the conformity assessment. The procedures, design
review requirements, testing requirements, and conformity assessment documentation requirements are
specified in Clause 5. Completion of devices level conformity assessment is a pre-requisite to carry out EMS
conformity assessment. The conformity assessment is undertaken in the following key stages:
1. device level;
2. EMS level;
3. EMS re-verification and device / ancillary component replacement.
Stage 1 is mandatory for newly manufactured devices and is covered by EN 50463-2, EN 50463-3 and
EN 50463-4. Stages 2, 3 are mandatory for every EMS in accordance with the scope as specified in
Clause 1. The conformity assessment, undertaken during stages 2 and 3, deals primarily with system level
requirements, and it does not replicate the detail in stage 1.
4.2 Situation of applicability
The EMS conformity assessment described in this part applies in case of:
• EMS integration,
• EMS installation,
• EMS periodic re-verification,
• EMS device / ancillary component replacement.
4.3 General Methodology
The conformity assessment is undertaken using the following methods:
a) device design review;
b) device type test;
c) device routine test;
d) EMS integration design review;
e) EMS integration type test
f) EMS installation design review;
g) EMS installation type test;
h) EMS installation routine test.
Furthermore the following methods are covering the re-verification and replacement:

i) EMS periodic re-verification;
j) EMS device / ancillary component replacement.
Methods a) to c), are used at device level and the conformity assessment arrangements are covered by
EN 50463-2, EN 50463-3 and EN 50463-4. Methods d) to j) apply at EMS system level and are described in
this part of the EN 50463 series of standards.
Each method described generates evidence of conformity. Methods d) to h) are listed in logical order. They
may be undertaken in the same testing environment.
Completing the integration methods d) and e) allows the possibility of using this integration conformity
assessment in conjunction with multiple installation conformity assessment’s. This approach can be
employed when the same EMS equipment type is to be used on several different traction unit types, using
multiple installation conformity assessment’s to deal with the installation issues only.
The Figures 2 illustrates the methods of conformity assessment arrangements.

4.4 EMS Specific Methodology
Methods d) to j) apply at EMS system level, the methods i) and j) address re-verification and device
component replacement. Methods are listed in logical order. They may be undertaken in the same testing
environment.

The installation routine test demonstrates that the type tested EMS functionality is assured for each
installation on traction units of the same type.
4.4.6 EMS periodic re-verification
The EMS periodic re-verification activities are used to ensure the conformity assessment of an in-service
EMS remains valid, where necessary confirm metrological properties, so that the EMS can continue to be
used.
4.4.7 Replacement of devices and ancillary components
If a device / ancillary component of an in-service EMS is replaced, the substitution procedure ensures that
the EMS conformity assessment remains valid and the EMS can continue to be used.
