IEC 61097-1:2007

Global maritime distress and safety system (GMDSS) - Part 1: Radar transponder - Marine search and rescue (SART) - Operational and performance requirements, methods of testing and required test results

IEC 61097-1:2007 specifies the performance standards and type testing of marine radar transponders used in search and rescue operations at sea (SART), as required by Regulation 6.2.2 of Chapter III, and 7.1.3 and 8.3.1 of Chapter IV of the 1988 amendments to the 1974 International Convention for Safety of Life at Sea (SOLAS), and which is associated with IEC 60936 (Shipborne radar) and IEC 60945 (General requirements).
This standard incorporates the performance standards of IMO Resolutions A.530 (13) and A.802 (19) (Survival craft radar transponders for use in search and rescue operations) and the technical characteristics for such transponders contained in ITU-R Recommendation M.628-4, and takes account of the general requirements contained in IMO Resolution A.694 (17).
This second edition cancels and replaces the first edition published in 1992. This edition constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
- some amendments to bring the standard up to date with newer IMO resolutions and ITU recommendations. In particular, in 1995, the IMO adopted new performance standards for the SART in resolution A.802(19) which replaced those of resolution A.697(17). This new resolution introduced a new requirement for the SART to be provided with a pole arrangement. In 2006, the ITU-R revised recommendation M.628 to permit the optional use of circular polarisation with the SART;
- the Introduction has been deleted as it was of historical interest only;
- Annex A, which contained details of the parts of the IEC 61097 series of standards, has been deleted as this information is now available from this Foreword;
- Annex B which contained a Bibliography has been deleted and the information moved into the normative references.

Système mondial de détresse et de sécurité en mer (GMDSS) - Partie 1 : Répondeur radar - Recherche et sauvetage maritime (SAR) - Exigences opérationnelles et de fonctionnement, méthodes d'essai et résultats exigibles

L'IEC 61097-1:2007 définit les normes de performance et les essais de type des répondeurs radar maritimes utilisés pour les opérations de recherche et de sauvetage en mer (SAR), comme exigé par les règles 6.2.2 du Chapitre III, ainsi qu'en 7.1.3 et 8.3.1 du Chapitre IV des amendements de 1988 à la Convention internationale pour la sauvegarde de la vie humaine en mer (SOLAS) de 1974, et qui est associée à l'IEC 60936 (Radars de navire) et à l'IEC 60945 (Spécifications générales).
La présente Norme inclut les normes de performance des Résolutions A.530 (13) et A.802 (19) (Répondeurs radar pour embarcations et radeaux de sauvetage destinés à être utilisés lors des opérations de recherche et de sauvetage) de l'OMI ainsi que les caractéristiques techniques de ces répondeurs contenues dans la Recommandation ITU-R M.628-4, et tient compte des exigences générales contenues dans la Résolution A.694 (17) de l'OMI.
Cette deuxième édition annule et remplace la première édition parue en 1992. Cette édition constitue une révision technique.
Les principales modifications apportées à l’édition précédente sont les suivantes:
- certains amendements destinés à mettre la norme à jour conformément à des résolutions de l'OMI et des recommandations UIT plus récentes. En particulier, en 1995, l'OMI a adopté de nouvelles normes de performance relatives à la recherche et au sauvetage maritime (SART) dans la résolution A.802(19) qui a remplacé les normes de la résolution A.697(17). Cette nouvelle résolution a introduit une nouvelle exigence relative aux répondeurs SAR à prendre en considération en même temps qu’une réorganisation des équipements montés sur le mât. En 2006, la recommandation révisée ITU-R M.628, qui a autorisé l'utilisation de la polarisation circulaire avec la recherche et le sauvetage maritime;
- l'Introduction a été supprimée, car elle présentait uniquement un intérêt historique;
- l'Annexe A, qui contenait des détails relatifs aux parties de la série de normes IEC 61097, a été supprimée puisque ces informations sont désormais disponibles dans le présent Avant-propos;
- l'Annexe B contenant une Bibliographie a été supprimée et les informations associées ont été déplacées dans les références normatives.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
International Standard IEC 61097-1 has been prepared by IEC technical committee 80:
Maritime navigation and radiocommunication equipment and systems.
This second edition cancels and replaces the first edition published in 1992. This edition
constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– some amendments to bring the standard up to date with newer IMO resolutions and ITU
recommendations. In particular, in 1995, the IMO adopted new performance standards for
the SART in resolution A.802(19) which replaced those of resolution A.697(17). This new
resolution introduced a new requirement for the SART to be provided with a pole

use of circular polarisation with the SART;
– the Introduction has been deleted as it was of historical interest only;
– Annex A, which contained details of the parts of the IEC 61097 series of standards, has
been deleted as this information is now available from this Foreword;
– Annex B which contained a Bibliography has been deleted and the information moved into
the normative references.
The text of this standard is based on the following documents:
FDIS Report on voting
80/479/FDIS 80/485/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.
