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.

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.

EQUIPMENT AND SYSTEMS –
General requirements –
Methods of testing and required test results
1 Scope
This International Standard assists in meeting a requirement of the International Convention
for Safety of Life at Sea (SOLAS), adopted by the International Maritime Organization (IMO),
that the radio equipment defined in chapters III and IV, and the navigation equipment defined
in chapter V of the Convention, be type-approved by administrations to conform with
performance standards not inferior to those adopted by the IMO. (Administrations are defined
by the IMO as governments of the states whose flags the ships are entitled to fly.)
The performance standard for general requirements for shipborne radio equipment and
electronic navigation aids that has been adopted by the IMO is given in IMO Resolution A.694
and is reproduced in this standard as annex A, which forms the basis for this standard.
Reference is made, where appropriate, to IMO Resolutions A.694 and A.813 and all
subclauses whose wording is identical to that in the resolutions are printed in italics.
This standard specifies minimum performance requirements, methods of testing and required
test results for general requirements which can be applied to those characteristics common to
all equipment described hereunder:
a) shipborne radio equipment forming part of the global maritime distress and safety system
required by the International Convention for Safety of Life at Sea (SOLAS) as amended,
and by the Torremolinos International Convention for the Safety of Fishing Vessels as
amended;
b) shipborne navigational equipment required by the International Convention for Safety of
Life at Sea (SOLAS) as amended, and by the Torremolinos International Convention for
the Safety of Fishing Vessels as amended, and to other navigational aids, where
appropriate; and
c) for EMC only, all other bridge-mounted equipment, equipment in close proximity to
receiving antennas, and equipment capable of interfering with safe navigation of the ship
and with radio-communications (see IMO Resolution A.813).
NOTE For EMC, this standard is in the IEC category “product family”.
The requirements of this standard are not intended to prevent the use of new techniques in
equipment and systems, provided the facilities offered are not inferior to those stated.

4 Minimum performance requirements
4.1 General
4.1.1 Introduction
All equipment shall be subjected to all the appropriate tests in this standard unless otherwise
specified in the relevant equipment standard, with the following exceptions:
a) the solar radiation test, the oil test and the corrosion test shall be waived where the
manufacturer is able to produce evidence that the components, materials and finishes
employed in the equipment would satisfy the test;
b) the safety test for visual display units (VDU) shall be waived where the manufacturer is
able to produce evidence that the VDU would satisfy the tests;
c) the X-radiation test shall be waived where the manufacturer is able to produce evidence
that the equipment would satisfy the test.
The relevant equipment standard referred to above shall contain the following information
which is required for the conduct of tests in this standard:
– equipment category (see 4.4);
– performance test (see 5.1);
– performance check (see 5.1);
– pre-conditioning for environmental tests (see 8.1).
In order to assist administrations in granting type approval as required by SOLAS, the
laboratory or test facility conducting technical tests shall be approved for this purpose, and
shall conform to appropriate international standards concerning calibration and quality control.
Operational checks, particularly those involving subjective judgement, shall be conducted by
personnel having appropriate qualifications and nautical knowledge.
Requirements and the related tests are cross-referenced in annex F.
4.1.2 General requirements
(A.694/1.2) Where an equipment provides a facility which is additional to the minimum
requirements of both this standard and the relevant equipment standard, the operation and,
as far as is reasonably practicable, the malfunction of such additional facility shall not
degrade the performance of the equipment.
(A.694/2) Equipment shall be installed in such a manner that it is capable of meeting the
requirements of applicable performance standards adopted by IMO.
There are no tests given in this standard to support this IMO requirement as this standard
applies solely to equipment. Guidance on installation of equipment can be found in IEC 60092
and IEC 60533 and by reference to equipment manuals.
