ELECTRICAL AND ELECTRONIC INSTALLATIONS IN SHIPS –
ELECTROMAGNETIC COMPATIBILITY
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 60533 has been prepared by IEC technical committee18: Electrical
installations of ships and of mobile and fixed offshore units.
This second edition cancels and replaces the first edition, published in 1977, and constitutes a
technical revision.
The following changes have been made:
– Section 7 "Methods of measurement and suppression techniques" has been deleted.
The methods of measurement have been aligned with CISPR 16-1, CISPR 16-2 and
the IEC 61000 series. The requirements of IEC 60945 and IEC 60092-101, IEC 60092-204
and IEC 60092-504 have been incorporated as far as possible.
– A new annex A "IMO Resolution A.813 (19) has been added as an informative part.
– A new annex B "General EMC planning procedures" has been prepared as an informative
part of this standard.
– A new annex C "Measures to achieve EMC" has been prepared as an informative part of
this standard. It contains guidelines and recommendations for organizational and technical
measures to achieve EMC.
– Equipment and installation groups A to E have been updated to include "non-electrical
items and equipment" and "integrated systems" in annex C.
– Chapter II "Vital interference suppression components" has been deleted. This topic is now
sufficiently described in the referenced IEC standards given in annex C.

FDIS Report on voting
18/870/FDIS 18/874/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.
Annexes A, B and C are for information only.
A bilingual version of this standard may be issued at a later date.
The committee has decided that this publication remains valid until 2004-01.
At this date, in accordance with the committee’s decision, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
Electrical installations of ships with electric and/or electronic systems need to operate under a
wide range of environmental conditions.
The control of undesired electromagnetic emission ensures that no other device on board will
be unduly influenced by the equipment under consideration. Suitable limits are specified.
On the other hand, the equipment needs to function without degradation in the normal elec-
tromagnetic environment. The limit values for immunity, specified in this standard, have been
chosen under this assumption. Equipment which is tested and installed in accordance with this
standard meets the relevant IMO requirements. Special risks, for instance lightning strikes,
transients from the operation of circuit breakers and electromagnetic radiation from radio
transmitters are also covered.
Complex electric and/or electronic systems require EMC planning in all phases of design
and installation, considering the electromagnetic environment, any special requirements and the
equipment performance.
This second edition is applicable to electromagnetic compatibility of all electrical and electronic
installations in ships.

ELECTRICAL AND ELECTRONIC INSTALLATIONS IN SHIPS –
ELECTROMAGNETIC COMPATIBILITY
1 Scope
This International Standard specifies minimum requirements for emission, immunity and perform-
ance criteria regarding electromagnetic compatibility (EMC) of electrical and electronic equipment
for ships. It assists in meeting the requirements of IMO resolution A.813 (see annex A).
Equipment which is tested and installed in accordance with this standard meets the relevant
IMO requirements.
NOTE 1 The normative part of this standard has been prepared as a product family EMC standard.
NOTE 2 Effects on human beings are not the subject of this standard.
This standard further gives guidelines and recommendations on the measures to achieve EMC
in the electrical and electronic installations of equipment groups:
a) group A: radio communication and navigation equipment;
b) group B: power generation and conversion equipment;
c) group C: equipment operating with pulsed power;
d) group D: switchgear and control systems;
e) group E: intercommunication and signal processing equipment;
f) group F: non-electrical items and equipment;
g) group G: integrated systems.
The basic EMC standard for groups A and C is IEC 60945.
NOTE This standard does not specify unsafe operation and basic safety requirements such as protection against
electric shock and dielectric tests for equipment.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, 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. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
