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.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
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.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.

INTRODUCTION
In consideration that IEC 62625-1 specifies the ODDRS (On Board Driving Data Recording
System) requirements in terms of functional and system descriptions, a standardized
conformity testing approach was developed in this standard on the base of the ISO/IEC 9646
series standards.
The ISO/IEC 9646 series standards apply to the assessment of communication protocol and
are based on the concept of PICS (Protocol Implementation Conformity Statement) and PIXIT
(Protocol Implementation eXtra Information for Testing). This standard extends the concepts
to functional and system description introducing FICS (Function Implementation Conformity
Statement), SICS (System Implementation Conformity Statement) and IXIT (Implementation
eXtra Information for Testing).
The IEC 62625-1 requirements implementation, formally described by FICS, SICS and IXIT
are verified by design review and other test methods applied to ODDR Unit and ODDRS
installed on the train.

Part 2: Conformity testing
1 Scope
This part of IEC 62625 covers the standardized test methods for verifying the compliance of
an On board Driving Data Recording System implementation with the requirements specified
by IEC 62625-1.
Furthermore, it covers the conformity testing criteria for designed and manufactured ODDRS.
This part of IEC 62625 includes the list of the requirements specified by IEC 62625-1 and the
relevant acceptance conditions for ODDRS at design review, type test and routine test
phases. For the train level design review and train level test phases, this part provides
guidelines for the conformity testing methods to be applied to the ODDRS installed on the
train.
This part does not cover the conformity assessment schemes that, according to ISO/IEC
Directives Part 2, are the responsibility of ISO policy committee “Committee on conformity
assessment” (ISO/CASCO). Consequently, this part does not include elements related to
conformity assessment aspects other than design review and testing provisions for the
products, processes or services which implements the requirements specified in IEC 62625-1.
This part does not delete, change or interpret the general requirements for conformity
assessment procedures and vocabulary detailed in ISO/IEC 17000.

4.1.3.2 Device/function conformity checking
The compliance to the requirements specified by IEC 62625-1:2013 is mandatory for all the
functions/devices composing the ODDR unit. Each device/function shall be verified according
to the provided test procedure.
Considering that the user of this standard is free, at design level, to choose the functions
mapping over devices, several situations may apply:
• One complete function is carried and executed by one device.
• More than one function is carried and executed by one device.
• One function is carried and executed by more devices, each one executing a part (sub-
function) of the complete function.
Following this consideration, the device/function conformity checking is only covering the
capability of the device to execute the functions/sub-functions which are carried by such
device.
The test procedures are defined by the designer. The passing of such test procedure are a
prerequisite to run the tests specified by 4.1.3.4 and 4.1.3.6.
Specific requirements related to practices necessary to assure the integration at ODDR unit
and at train level are to be determined in accordance with relevant railway standards during
the following phases.
– 12 – IEC 62625-2:2016 © IEC 2016
4.1.3.3 Subsystem integration design review
The design review evaluates the design of an ODDR Unit against the requirements specified
by IEC 62625-1:2013, through examination of technical documentation for the IUT together
with any supporting evidence.
The functional and system requirements of ODDR unit shall be listed and described
according to the FICS and SICS specified by the Clauses 5 and 6.
The design review shall also include documentation on reliability, availability, maintainability,
interfaces, installation requirements and constraints.
If there are any changes to the ODDR unit, an evaluation shall be performed in order to
identify if its functionality has been affected and which impact exists on the system. If so, the
relevant test methods shall be applied in order to verify that the ODDR unit still complies with
the requirements of IEC 62625-1:2013.
The Design Review test methods are specified in Table 6 and Table 24 (phase DR).
4.1.3.4 Subsystem integration type test
The aim of the type test of the ODDR Unit is to verify that the functional and system
requirements specified by IEC 62625-1:2013 are met by the ODDR Unit.
The description of functional and system requirements which are implemented by the design
of IUT and are submitted to type test shall be listed and described by the FICS and SICS
specified by the Clauses 5 and 6.
Type test shall be performed on one or more unit of a given design and manufacturing
procedure to ensure the full coverage of the specified requirements.
If there is any change to a previously tested unit, the type test shall repeat at least those test
cases which are affected by the change.
The type test methods are specified in Table 6 and Table 24 (phase TT).
4.1.3.5 Subsystem type and traction unit type – Train level design review
The train level design review verifies the integration of an ODDRS in the train, through
examination of technical documentation together with any supporting evidence.
The train level design review shall include documentation on reliability, availability,
maintainability, interfaces, installation requirements and constraints.
The Train Level Design Review test methods are specified in Table 6 and Table 24 (phase
TLDR).
4.1.3.6 Subsystem type and traction unit type – Train level test
The aim of train level test is to verify some functional and system requirements of the
ODDRS after the installation in the train, in order to assure that the installation has not
affected the fulfilment of those requirements.
The test cases, to be carried out during the train level test, are listed in Table 6 and Table 24.
The Train Level Test methods are specified in Table 6 and Table 24 (phase TLT).

4.2 Implementation conformity statements
4.2.1 General
The functional requirements are verified according to the declaration statements called FICS
which are relevant to 4.2 of IEC 62625-1:2013.
The system requirements are verified according to the declaration statements called SICS
which are relevant to 4.3 of IEC 62625-1:2013.
The supplier shall determine which extra IUT specific information is necessary for testing the
functional and system requirements. The IUT supplier shall complete an IXIT pro-forma with
the necessary information, and make it available.
4.2.2 FICS and SICS
To evaluate the conformity of a particular implementation, it is necessary to have a statement
of the capabilities and options that have been implemented with reference to the
requirements and any features which have been omitted, so that the implementation can be
checked for acceptance against the requirements specified respectively in 4.2 and in 4.3 of
IEC 62625-1:2013, and against those requirements only. Such statements are called
respectively:
• Function Implementation Conformity Statement (FICS).
• System Implementation Conformity Statement (SICS).
The structure and instructions for completion of the FICS and SICS are given in the
informative Annex A.
4.2.3 IXIT
In order to test a function implementation, the test authority needs information relating to the
IUT and its testing environment in addition to that provided by the FICS and SICS. This
"Implementation eXtra Information for Testing" (IXIT) will be provided by the supplier and
system integrator submitting the implementation for testing, as a result of consultation with
the test authority.
The IXIT may contain the following information:
a) information needed by the test authority in order to be able to run the appropriate test
suite on the specific system (e.g. information related to the test method to be used to run
the test cases, addressing information);
b) information already mentioned in the FICS and which needs to be made precise (e.g. a
timer value range which is declared as a parameter in the FICS should be specified in the
IXIT);
c) information to help determine which capabilities stated in the FICS as being supported
are testable and which are not testable;
d) other administrative matters (e.g. the IUT identifier, reference to the related FICS).
The IXIT shall not conflict with the appropriate FICS or SICS.
