Part 5: Conformance test
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates
closely with the International Organization for Standardization (ISO) in accordance with conditions determined
by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.

INTRODUCTION
Three levels are introduced for categorizing EMS as described in this document in 4.1.
This part is Part 5 of the IEC 62888 series which consists of the following parts, under the
common title Railway applications – Energy measurement on board trains:
Part 1: General
Part 2: Energy measurement
Part 3: Data handling
Part 4: Communication
Part 5: Conformance test
Part 6: Requirements for purposes other than billing
This series of International Standards follows the functional guidelines description in Annex A,
“Principles of conformity assessment”, of ISO/IEC 17000:2004 tailored to the Energy
Measurement System (EMS).
The Energy Measurement System (EMS) provides measurement and data suitable for
applications such as energy management, energy saving, billing and others.
This series of International Standards uses the functional approach to describe the EMS.
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 the IEC 62888 series
This series of International Standards is divided into six parts. The titles and brief descriptions
of each part are given below:
IEC 62888-1 – General
The scope of IEC 62888-1 is the Energy Measurement System (EMS).
IEC 62888-1 provides system level requirements for the complete EMS and common
requirements for all devices implementing one or more functions of the EMS.
IEC 62888-2 – Energy measurement
The scope of IEC 62888-2 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 AC 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 (CL) system and
the Current Measurement Function measures the current taken from and returned to the CL
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 Measured Data.
All relevant metrological aspects are covered in this part of IEC 62888.
IEC 62888-2 also defines the conformance test of the EMF.
IEC 62888-3 – Data handling
The scope of IEC 62888-3 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 Measured 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.
IEC 62888-3 also defines the conformance test of the DHS.
IEC 62888-4 – Communication
The scope of IEC 62888-4 is the communication services.
This part of IEC 62888 gives requirements and guidance regarding the data 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.
IEC 62888-4 also defines the conformance test of the communications services.
IEC 62888-5 – Conformance test
The scope of IEC 62888-5 is the conformance test procedures for the EMS.
IEC 62888-5 also covers re-verification procedures and conformance test in the event of the
replacement of a device of the EMS.
IEC 62888-6 – Requirements for purposes other than billing
The scope of IEC 62888-6 is to specify the requirements for EMS to be used for
benchmarking, daily energy consumption monitoring, technical research and development.
This part provides the requirements for monitoring consumed energy on board in daily
services in an easy way and the measured data are applicable for general purposes in
industry such as energy management, energy saving, etc. However, this part is not applicable
for billing purposes.

Part 5: Conformance test
1 Scope
This part of IEC 62888 specifies the conformance test arrangements for newly manufactured
EMS installed on a traction unit. This includes the integration conformance test and
installation conformance test. In addition, this document also specifies the conformance test
procedures for device and ancillary component replacement (e.g. due to damage in service),
and periodic check to verify the EMS conformance test remains valid.
The assessment methods d) to j) in 4.3 apply at EMS system level. The methods are covered
by IEC 62888-5 for Level 1 and by IEC 62888-6 for Level 2 and Level 3.
This document does not include elements related to conformance test aspects other than
design review and testing provisions for the products, processes or services specified.
Consequently, this document does not delete, change or interpret the general requirements
for conformance test procedures and vocabulary detailed in ISO/IEC 17000.

4 Conformance test approach
4.1 General
This clause specifies the structure and methodology for the conformance test. The
procedures, design review requirements, testing requirements, and conformance test
documentation requirements are specified in Clause 5. Completion of devices level
conformance test is a pre-requisite to carry out EMS conformance test. The conformance test
is undertaken in the following key stages:
a) device level;
b) EMS level;
c) EMS re-verification and device / ancillary component replacement.
Stage 1 is mandatory for newly manufactured devices and is covered by IEC 62888-2,
IEC 62888-3 and IEC 62888-4. Stages 2, 3 are mandatory for every EMS in accordance with
the scope as specified in Clause 1. The conformance test, 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 conformance test described in this part applies in case of:
• EMS integration,
• EMS installation,
• EMS periodic re-verification,
• EMS device / ancillary component replacement.

– 12 – IEC 62888-5:2018 © IEC 2018
4.3 General methodology
The conformance test is undertaken using the following methods, they are listed in logical
order and may be undertaken in the same testing environment:
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 cover 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. Conformance test arrangements are covered by
IEC 62888-2, IEC 62888-3, IEC 62888-4 for Level 1 and by IEC 62888-6 for Level 2 and
Level 3.
Methods d) to j) apply at EMS system level. The methods are covered by IEC 62888-5 for
Level 1 and by IEC 62888-6 for Level 2 and Level 3.
Each method described generates evidence of conformance.
Completing the integration methods d) and e) allows the possibility of using this integration
conformance test in conjunction with multiple installation conformance tests. This approach
can be employed when the same EMS equipment type is to be used on several different
traction unit types, using multiple installation conformance tests to deal with the installation
issues only.
Figure 2 illustrates the methods of conformance test arrangements.

4.4.5 EMS installation type test
The installation type test demonstrates that the integrated EMS of a specific equipment type,
when installed on board on a specimen representative of the traction unit type, is functioning
as intended in accordance with this series of standards.
4.4.6 EMS installation routine test
The installation routine test demonstrates that the type tested EMS functionality is ensured for
each installation on traction units of the same type.
4.4.7 EMS periodic re-verification
The EMS periodic re-verification activities are used to ensure the conformance test of an in-
service EMS remains valid, where necessary to confirm metrological properties, so that the
EMS can continue to be used.
4.4.8 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 conformance test remains valid and the EMS can continue to be used.
5 Conformance test procedures
5.1 General

EMS of a specific equipment type shall have passed the appropriate device level conformance
test in accordance with IEC 62888-2, IEC 62888-3, and IEC 62888-4.
If design changes are made to traction unit, no conformance test of EMS is required, unless
the changes affect the EMS.
5.2 EMS integration design review
5.2.1 EMS integration design review documentation
In order to carry out the EMS integration design review, the following documentation shall be
provided by the EMS integrator for each designated EMS equipment type:

5.3.3.4 Power-down
Energise the IUA such that it simulates the EMS operating with all external equipment
behaving as intended before and during the power down test.
Power down the EMS, and check:
a) the EMS has successfully powered down,
b) any data being recorded during power down is successfully processed and stored.
NOTE Simulated operation can use signals introduced at the sensor outputs as an alternative to injecting signals
directly into the EMS input.
5.3.3.5 Traction supply system change
Simulate one traction supply system change and check that the requirements stated in
IEC 62888-1:2018, 4.2.5.1 are fulfilled.
NOTE The assessment procedure can use simulated output from the sensors as an alternative to injecting signals
directly into the EMS input.
5.3.3.6 EMS data flow test
Simulate input to the EMS and check the correlation between the input signals applied and
the data stored in the DHS, also ensure that the CEMD is stored correctly.
NOTE 1 The assessment procedure can use simulated output from the sensors as an alternative to injecting
signals directly into the EMS input.
Simulate data export from the DHS via the local service port and compare the data stored in
the DHS with data exported and ensure the data exported is identical to that held in the DHS.
Simulate data export from the DHS to the DCS and compare the data stored in the DHS with
the data stored in the DCS and ensure the two data sets are identical.
NOTE 2 The DCS can be the actual or a simulated one.
