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 specifications, 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 60945 has been prepared by IEC technical committee 80: Maritime
navigation and radiocommunication equipment and systems.
This fourth edition cancels and replaces the third edition published in 1996 and constitutes a
technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
80/345/FDIS 80/349/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 3.
Annex A forms an integral part of this standard.
Annexes B, C, D, E, F, and G are for information only.

The committee has decided that the contents of this publication will remain unchanged until 2007.
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
IEC 945 was originally produced to give test methods and, where appropriate, limit values to
the IMO Resolution A.574(14) which was a recommendation on general requirements for
electronic navigational aids. (It has subsequently been replaced, see below.) The tests
dealing with electromagnetic immunity could not be produced in time for the publication of the
original standard, and these were added later in 1992 as amendment 1.
In 1991 the IMO, when discussing the changes that would arise with the introduction of the
global maritime distress and safety system (GMDSS), noted that in future, radio equipment
would be installed on the bridge of a vessel alongside the navigation equipment instead of in
a special radio room as hitherto. The IMO consequently withdrew Resolution A.574(14), and a
corresponding Resolution A.569(14) dealing with the general requirements of radio
equipment, and replaced them with IMO Resolution A.694(17). A second edition of IEC 945
was rapidly prepared to reflect this change.
The third edition of IEC 945 in 1996 was a complete revision which aligned the test methods
with appropriate other IEC standards and introduced, wherever possible, the requirements of
the classification societies. The scope was extended to make the standard applicable
additionally to other equipment installed on and around the bridge of a ship with regard to
EMC. A new class of equipment – “portable” – was added, together with better definitions of
operational tests which involve subjective judgement and descriptions of operational and
durability aspects of software.
This fourth edition (now IEC 60945) extends the detail of operational tests particularly for
equipment which is operated through software menus. This has been derived from an
exhaustive investigation of appropriate references as described in the Bibliography. The
layout of clause 4 (Minimum performance requirements) has been changed to give a better
grouping of ergonomics, hardware and software requirements.
The EMC tests have been revised with the frequency range having been extended from 1 GHz
to 2 GHz.
Clarifications to the text of the third edition have been added where experience has shown a
need and the references have been updated.
A comparison of the test requirements in the third and fourth editions is given in annex G to
assist manufacturers and test houses in the use of the new edition.
