FOREWORD
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
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61000-4-6 has been prepared by subcommittee 77B: High-
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This standard forms part 4-6 of IEC 61000. It has the status of a basic EMC publication in
accordance with IEC Guide 107, Electromagnetic compatibility – Guide to the drafting of
electromagnetic compatibility publications.
This consolidated version of IEC 61000-4-6 consists of the second edition (2003) [documents
77B/377/FDIS and 77B/384/RVD], its amendment 1 (2004) [documents 77B/426/FDIS and
77B/431/RVD] and its amendment 2 (2006) [documents 77B/492/FDIS and 77B/502/RVD].

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 4-6: Testing and measurement techniques –
Immunity to conducted disturbances,
induced by radio-frequency fields
1 Scope and object
This part of IEC 61000-4 relates to the conducted immunity requirements of electrical and
electronic equipment to electromagnetic disturbances coming from intended radio-frequency
(RF) transmitters in the frequency range 9 kHz up to 80 MHz. Equipment not having at least
one conducting cable (such as mains supply, signal line or earth connection) which can couple
the equipment to the disturbing RF fields is excluded.
NOTE 1 Test methods are defined in this part for measuring the effect that conducted disturbing signals, induced
by electromagnetic radiation, have on the equipment concerned. The simulation and measurement of these
conducted disturbances are not adequately exact for the quantitative determination of effects. The test methods
defined are structured for the primary objective of establishing adequate repeatability of results at various facilities
for quantitative analysis of effects.
The object of this standard is to establish a common reference for evaluating the functional
immunity of electrical and electronic equipment when subjected to conducted disturbances
induced by radio-frequency fields. The test method documented in this part of IEC 61000
describes a consistent method to assess the immunity of an equipment or system against a
defined phenomenon.
NOTE 2 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test
standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels
and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the
evaluation of the value of particular immunity tests for their products.

equipment necessary to provide the equipment under test (EUT) with the signals required for
normal operation and equipment to verify the performance of the EUT
3.3
clamp injection
clamp injection is obtained by means of a clamp-on “current” injecting device on the cable:

which the injection is made;
– electromagnetic clamp (EM clamp): injection device with combined capacitive and
inductive coupling
3.4
common-mode impedance
ratio of the common mode voltage and the common-mode current at a certain port
NOTE This common mode impedance can be determined by applying a unity common mode voltage between the
terminal(s) or screen of that port and a reference plane (point). The resulting common mode current is then
measured as the vectorial sum of all currents flowing through these terminal(s) or screen (see also Figures 8a and
8b).
3.5
coupling factor
ratio given by the open-circuit voltage (e.m.f.) obtained at the EUT port of the coupling (and
decoupling) device divided by the open-circuit voltage obtained at the output of the test
generator
3.6

4 General
The source of disturbance covered by this part of IEC 61000 is basically an electromagnetic
field, coming from intended RF transmitters, that may act on the whole length of cables
connected to installed equipment. The dimensions of the disturbed equipment, mostly a sub-
part of a larger system, are assumed to be small compared with the wavelengths involved. The
in-going and outgoing leads (e.g. mains, communication lines, interface cables) behave as
passive receiving antenna networks because of their length, which can be several wavelengths.
Between those cable networks, the susceptible equipment is exposed to currents flowing
“through" the equipment. Cable systems connected to an equipment are assumed to be in
resonant mode (λ/4, λ/2 open or folded dipoles) and as such are represented by coupling and
decoupling devices having a common-mode impedance of 150 Ω with respect to a ground
reference plane. Where possible the EUT is tested by connecting it between two 150 Ω
common-mode impedance connections: one providing an RF source and the other providing a
return path for the current.
This test method subjects the EUT to a source of disturbance comprising electric and magnetic
fields, simulating those coming from intentional RF transmitters. These disturbing fields (E and
H) are approximated by the electric and magnetic near-fields resulting from the voltages and
currents caused by the test set-up as shown in Figure 2a.
The use of coupling and decoupling devices to apply the disturbing signal to one cable at the
time, while keeping all other cables non-excited, see Figure 2b, can only approximate the real
situation where disturbing sources act on all cables simultaneously, with a range of different
amplitudes and phases.
Coupling and decoupling devices are defined by their characteristics given in 6.2. Any coupling
and decoupling device fulfilling these characteristics can be used. The coupling and decoupling
networks in Annex D are only examples of commercially available networks.
