FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61174 has been prepared by IEC technical committee 80: Maritime
navigation and radiocommunication equipment and systems.
The text of this standard is based on the following documents:

FDIS Report on voting
80/190/FDIS 80/201/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.
Annexes A, B, C, D, E and F form an integral part of this standard.
Annex G is for information only.
A bilingual version of this standard may be issued at a later date.

OPERATIONAL AND PERFORMANCE REQUIREMENTS,

METHODS OF TESTING AND REQUIRED TEST RESULTS

1 Scope
This International Standard specifies the performance requirements, methods of testing and
required test results of equipment conforming to performance standards not inferior to those
adopted by the IMO in resolution A.817.
This standard is based upon the performance standards of IMO resolution A.817, and is also
associated with IMO resolution A.694 and IEC 60945. Reference is made, where appropriate,
to IMO resolution A.817, and all subclauses whose wording is identical to that in the resolution
are printed in italics.
In association with the above IMO resolution A.817, are the International Hydrographic
Organization (IHO) publications S-52 and S-57. This standard has included extracts from the
above publications where they are applicable to this equipment. Where reference is made, all
subclauses whose wording is identical to that in the publications, are printed in italics.
The requirements of this standard are not intended to prevent the use of new techniques in
equipments and systems, provided the facilities offered are not inferior to those stated.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. At the time of publication, the editions
indicated were valid. All normative documents are subject to revision, and parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. Members of
IEC and ISO maintain registers of currently valid International Standards.
