Electronic railway equipment - On board driving data recording system - Part 2: Conformity testing

IEC 62625-2:2016 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. It also 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.

Matériel électronique ferroviaire - Système embarqué d'enregistrement de données de conduite - Partie 2: Essais de conformité

L'IEC 62625-2:2016 porte sur les méthodes d'essais normalisées pour la vérification de la conformité de la mise en oeuvre d'un système embarqué d'enregistrement des données de conduite aux exigences spécifiées dans l'IEC 62625-1. De plus, elle porte sur les critères d'essais de conformité des ODDRS conçus et fabriqués. La présente partie de l'IEC 62625 contient la liste des exigences spécifiées par l'IEC 62625-1, ainsi que les conditions d'acceptation correspondantes pour l'ODDRS lors des phases de revue de conception, d'essai de type et d'essai individuel de série. Pour les phases de revue de conception au niveau du train et d'essais au niveau du train, la présente partie donne les lignes directrices relatives aux méthodes d'essais de conformité à appliquer à l'ODDRS installé dans le train.

Part 2: Conformity testing
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.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

Internationals Standard IEC 62625-2 has been prepared by IEC Technical Committee 9:

Electrical equipment and systems for railways.
The text of this standard is based on the following documents:
FDIS Report on voting
9/2081/FDIS 9/2118/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,

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.
