Part 7-711: Requirements for special installations or locations –
Exhibitions, shows and stands
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 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 60364-7-711 has been prepared by IEC technical committee 64:
Electrical installations of buildings
The text of this standard is based on the following documents:
FDIS Report on voting
64/982/FDIS 64/999/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.

4 Artificial mains networks
Replace the existing title by the following new title:
4 Artificial networks for AC mains and other power ports
4.1 General
Replace the existing text, including Notes 1 and 2, by the following new text and new notes:
An AN is required to provide a defined impedance at radio frequencies at the terminals of the
EUT's port under test, to isolate the test circuit from unwanted RF signals on the laboratory
AC or DC supply mains, other power source or load connected to the EUT but not subject to
testing in relation with that EUT, and to couple the disturbance voltage to the measuring
receiver.
For use with measurements on LV AC mains power ports, there are two basic types of AMN,
the V-AMN, which couples the unsymmetric voltages, and the Δ-AMN, which couples the
symmetric and the asymmetric voltages separately. Use of practical implementations of these
AMNs is not restricted to LV AC mains power ports. In principle they can be used for
measurements on any kind of power port. The user of such artificial networks is
recommended to consult the respective product standard for guidance. The information and
advice in this standard for the AMN is hence valid for use of that AMN or another AN at power
ports other than LV AC mains power ports.
The AN or AMN is furnished with three ports, the port for connection to the laboratory AC or
DC supply mains or other power source or load (power/load port), the port for connection of
the EUT (EUT port), and the disturbance output port for connection of the measuring receiver
(receiver port).
NOTE 1 Examples of circuits of AMNs and ANs are given in Annex A.
NOTE 2 This clause specifies impedance and isolation requirements for ANs including the corresponding
measurement methods. Some background and rationale on the AMN related uncertainties are given in 6.2.3 of
CISPR/TR 16-4-1:2009 and in CISPR 16-4-2.
4.2 AMN impedance
Replace the existing title by the following new title:
4.2 AN impedances
Replace the existing text, including the note, by the following new text and new note:
The specification of the UM termination impedance of a V-AN includes the magnitude and the
phase of the impedance measured at an EUT terminal with respect to the reference ground,
when the V-AN’s receiver port is terminated with 50 Ω.
In case of a Δ-AMN or Δ-AN, the specification of the termination impedances includes the
magnitude and phase of the asymmetric (CM) termination impedance and the magnitude and
phase of the symmetric (DM) termination impedance. The asymmetric termination impedance

---------------------- Page: 6 ----------------------
CISPR 16-1-2:2014/AMD1:2017 – 5 –
© IEC 2017
is measured with the two (or more) active EUT terminals joined together relative to the
reference ground (as in Figure E.2). The symmetric termination impedance is measured
between each active pair of EUT terminals without relation to reference ground and requires
the use of a balun (see Figure K.2). For the impedance measurements, also for Δ-ANs the
receiver port shall be terminated by 50 Ω.
The impedance at the EUT terminals of the AN defines the termination impedance presented
to the EUT's port under test. For this reason, when a disturbance output terminal is not
connected to the measuring receiver, it shall be terminated by 50 Ω. To assure accurate
termination into 50 Ω of the receiver port, a 10 dB attenuator shall be used either inside or
external to the AN, the VSWR of which (seen from either side) shall be less than or equal to
1,2 to 1. The attenuation shall be included in the measurement of the voltage division factor
(see 4.11).
The impedance between each conductor (except PE, if any) of the EUT port and reference
ground shall comply with the provisions of 4.3, 4.4, 4.5 or 4.6, as appropriate, for any value of
external impedance, including a short circuit connected between the corresponding mains or
other power supply terminal and reference ground of the power/load port. This requirement
shall be met at all temperatures which the AN may reach under normal conditions for
continuous currents up to the specified maximum. The requirement shall also be met for peak
currents up to the specified maximum.
NOTE Because EUT connectors are not optimized for radio frequencies up to 30 MHz, the measurement of the
network impedance is carried out with special measurement adaptors to enable short-length connections. The OSM
(open/short/matched) calibration of the network analyzer is used to characterize the adaptors, taking the insertion
loss and the conductor lengths of the adaptors into account.

to 30 MHz

4.6 (Void)
4.7 150 Ω artificial mains delta-network (Δ-AMN) for use in the frequency range
150 kHz to 30 MHz

new tables:
4.7 150 Ω artificial delta-network (Δ-AN) for mains and other power ports for use in
the frequency range 150 kHz to 30 MHz
4.7.1 Requirements
In the frequency range of interest from 150 kHz to 30 MHz the AN shall have an impedance of
magnitude (150 ± 30) Ω with a phase angle not exceeding 40°, both between the EUT
terminals not including reference ground and between these two EUT terminals joined
together and the reference ground; see Table 8.
For proper performance in the range 150 kHz to 30 MHz, the AN shall also meet the
characteristics specified in Table 9 in the frequency range 9 kHz to 150 kHz. Adherence to
these characteristics does not however qualify the 150 Ω Δ-AN for use with measurements of
disturbance voltages in the range below 150 kHz. If necessary, another Δ-AN needs to be
specified for such measurements.

Measurement of Δ-AN parameters
Most of the typical characteristics of Δ-ANs are measured according to the instructions for
measurements on asymmetric artificial networks (AANs) in Annex E of this standard.
The asymmetric impedance at the EUT port of the Δ-AN is measured according to Figure E.2.
The calibration set-up and the set-up for measurement of the symmetric impedance at the
EUT port of the Δ-AN are shown in Figures K.1 and K.2, respectively.

Figure K.2 – Set-up for the measurement of the symmetric impedance
The LCL of the Δ-AN is measured according to Figure E.5 (however with modified resistor
values for a symmetric impedance of 150 Ω, instead of 100 Ω).
The asymmetric insertion loss between the EUT port and the port of the AN for connection to
the external power source or load is measured according to Figure E.6.
The symmetric insertion loss between the EUT port and the port of the AN for connection to
the external power source or load is measured according to Figure E.7.
The voltage division factor for asymmetric measurements is measured according to
Figure E.8.
