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

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
electromagnetic environment. The limit values for immunity, specified in this International
Standard, have been chosen under this assumption. Equipment which is tested and installed in
accordance with this International 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 third edition of IEC 60533 is applicable to electromagnetic compatibility of all electrical
and electronic installations in ships with metallic hull.
It is based on the assumption that the ship is constructed in such a way that metallic hull and
structure parts will significantly attenuate electromagnetic disturbance from the outer deck
environment to the inner deck environment and vice versa.

ELECTRICAL AND ELECTRONIC INSTALLATIONS IN SHIPS –
ELECTROMAGNETIC COMPATIBILITY (EMC) –
SHIPS WITH A METALLIC HULL
1 Scope
This International Standard specifies minimum requirements for emission, immunity and
performance criteria regarding electromagnetic compatibility (EMC) of electrical and electronic
equipment for ships with metallic hull. Additional or divergent requirements for ships with non-
metallic hull will be given in a future International Standard (IEC 62742).
This International Standard assists in meeting the relevant EMC requirements as stated in
SOLAS 74, Chapter IV, Regulation 6 and Chapter V, Regulation 17. Reference to this
International Standard is made in IMO Resolution A.813(19).
The normative part of this International Standard has been prepared as a product family EMC
standard.
This International Standard further gives guidelines and recommendations on the measures to
achieve EMC in the electrical and electronic installations of the following equipment groups:
a) group A: maritime navigation and radio communication equipment and systems;
b) group B: power generation and conversion equipment;
c) group C: equipment operating with pulsed power;
d) group D: switchgear and controlgear;
e) group E: intercommunication and signal processing equipment and control systems;
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. The EMC requirements according to
IEC 60945 apply additionally for
• bridge mounted equipment;
• equipment in close proximity to receiving antennas;
• equipment capable of interfering with the safe navigation of the ship and with radio
communication.
Effects on humans, like exposure to electromagnetic fields, and basic safety requirements
such as protection against electric shock and dielectric strength tests for equipment are not
within the scope of this International Standard.

Note 1 to entry: For EMC purposes, interconnections between metal parts equalize the different potentials and
require a low impedance in the frequency range considered. The frequency range considered includes the operating
as well as the disturbing frequencies. This frequency range and the physical size of the electrical device determine
the achievable equalization of potentials and thus the effectiveness of the grounding. The ground (earth) does not

That means only test facilities can be standardized, not the test and environmental conditions.
Note 2 to entry: In-situ testing can be performed, for example, in case of large and or heavy installations.
3.32
metallic hull
watertight main part or body of a ship made of metal or other equivalent conductive material
Note 1 to entry: It can be assumed that a metallic hull significantly reduces electromagnetic field strengths.
Note 2 to entry: Aside from that, measures are taken to reduce disturbance currents from entering or leaving the
inner deck environment.
4 General
Ships’ equipment and systems can be exposed to various kinds of electromagnetic
disturbances conducted by power or control lines or directly radiated from the environment.
The types and levels of disturbances depend on the particular conditions in which the system,
the subsystems or the equipment are installed and to be operated.
The individual equipment of a ship can also be a source of electromagnetic disturbances over a
wide frequency range, conducted through power and signal lines, or directly radiated, affecting
the performance of other equipment or influencing the external electromagnetic environment.
The acceptance criteria for the tests for immunity requirements are related to performance
criteria which are defined in terms of operational requirements.
For the emission limits, the objective of these requirements is to ensure that the disturbances
generated by the equipment and systems do not exceed a level which could prevent other
equipment and systems from operating as intended.
The emission limits of this International Standard may not, however, provide adequate
protection against interference to radio receivers when other ship equipment is used closer
than 3 m to the receiving antenna, see Annex A.
In special cases, for instance when highly susceptible equipment is being used closer than 3 m
to a transmitting antenna, additional mitigation measures may have to be employed to increase
the electromagnetic immunity beyond the limits specified in Clause 7.
NOTE The minimum immunity requirements in Clause 7 represent a typical electromagnetic environment and have
been selected so as to ensure an adequate level of immunity for ships.

5 EMC test plan
5.1 Objective
Prior to performing the tests, an EMC test plan shall be established. It shall contain as a
minimum the elements given in 5.2 to 5.5.
Tests detailed in this International Standard are normally conducted as type tests and shall be
carried out whenever possible at an EMC test laboratory. For test procedures, reference is
made to IEC basic standards.
However, in cases where type tests are impracticable (e.g. large mechanical dimensions of
equipment, functional control), individual tests may be performed. This can be done in situ, if
necessary, and in accordance with a tailored test procedure. In-situ testing is not as repeatable
as testing on a test site. Therefore, care should be taken when using the results of in-situ
testing on one site to predict compliance for a product from series production.
5.2 Configuration of equipment under test (EUT)
5.2.1 General
Ships' systems are not uniform assemblies. The type, number and installation of equipment,
whether installed individually or integrated, may vary from system to system. Hence it is not
reasonable to test every possible arrangement; however, it is recommended to carry out type
tests.
For a realistic simulation of the EMC situation (related both to emission and immunity), an
assembly of EUT with its auxiliary equipment, such as cabling, power supplies, etc. shall be
built to represent a realistic installation. This assembly shall be operated as far as possible
under normal conditions (including the software).
5.2.2 Assembly of EUT
If the EUT to be type tested is a system, subsystem or equipment likely to be installed at
distributed locations, one or more typical configurations with all components of the EUT shall
be chosen to reproduce the real installations. A justification for the chosen configurations shall
be provided in the EMC test plan.
NOTE The type test certificate issued after the test is valid only for the EUT composition listed in the EMC test
plan.
5.2.3 EUT interconnecting cables
A sufficient number of interconnecting cables shall be selected. At least one of each type of
interconnecting cable shall be used during testing in a representative configuration.
Interconnecting cables shall be standardized types, see Table B.1. Where special cables are
required, the manufacturer of the EUT should provide the specification.
5.2.4 Auxiliary equipment
A list of all auxiliary equipment shall be provided. The auxiliary equipment enumerated shall be
sufficient to simulate all realistic operational conditions and to ensure that all feasible types of
operation can be performed.
5.2.5 Cabling and grounding
The EUT shall be connected with all necessary cables and connected to ground in accordance
with the manufacturer's specifications and the installation requirements. There shall be no
additional grounding connections.

– 16 – IEC 60533:2015 © IEC 2015
5.3 Test pre-conditioning
5.3.1 Operational conditions
Typical operating modes of the EUT shall be defined by the manufacturer before testing,
considering that only the most typical functions of the equipment can be tested, for example
analogue signals at 0 %, 50 % and 100 % magnitude, or digital signals with typical impulse
trains. Particular attention shall be paid to the choice of critical mode.
5.3.2 Environmental conditions
EMC tests shall be performed under normal environmental conditions. Normal environmental
conditions shall consist of any convenient combination of temperature in the range +15 °C
to +45 °C and relative humidity in the range 20 % to 75 %.
When it is impractical to perform the tests under the environmental conditions defined above, a
note to this effect stating the actual environmental conditions prevailing during the tests shall
be appended to the test report.
5.3.3 Test software
The test software used for different modes of operation shall be identified.
5.4 Acceptance criteria
Pass/fail criteria for each port and test shall be specified. The acceptance criteria shall be
specified as quantitative values where possible.
For evaluation, the performance criteria are as follows:
Performance criterion A
The EUT shall continue to operate as intended during and after the test. No degradation of
performance or loss of function is allowed as defined in the relevant equipment standard and in
the technical specification published by the manufacturer.
Performance criterion B
The EUT shall continue to operate as intended after the test. No degradation of performance or
loss of function is allowed as defined in the relevant equipment standard and in the technical
specification published by the manufacturer. During the test, degradation or loss of function or
performance which is self-recoverable is however allowed; but no change of actual operating
state or stored data is allowed.
Performance criterion C
Temporary degradation or loss of function or performance is allowed during and after the test,
provided the function is self-recoverable, or can be restored by the operation of the controls as
defined in the relevant equipment standard and in the technical specification published by the
manufacturer.
5.5 Scope of EMC testing
Each test to be applied shall be specified in the EMC test plan based on the equipment test
matrix in Table 1. The description of tests, the test methods, the characteristics of the tests
and the test set-ups are given in the basic standards which are referred to in 6.2 and 7.2.
In addition, information needed for the practical implementation of the tests is given in this
International Standard. In some cases the EMC test plan should specify the application in
detail.
Performance criteria for the individual tests are given in Table 1.
NOTE Normally, no additional EMC tests are required beyond those stated in this International Standard.
6 Emission requirements
6.1 Conditions during the emission tests
Measurements shall be made with the EUT in the operating condition that produces the highest
emission level in the frequency band being investigated, see Clause 5.
NOTE 1 The conducted emission limits covered here are given on a port-by-port basis.
The radiated emission requirements within the range of receiving frequencies presume in the
deck and bridge zone a minimum distance of 3 m between the emitters and th
