Overview

IEC 63044-5-1:2017 is an essential international standard developed by the International Electrotechnical Commission (IEC) that defines Electromagnetic Compatibility (EMC) requirements for Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS). This product family standard specifies minimum EMC performance levels for devices and networks within HBES/BACS environments. It complements existing product EMC standards and applies specifically to devices lacking dedicated HBES/BACS EMC standards.

The standard details the EMC requirements for equipment interfaces connected to an HBES/BACS network, excluding connections to other network types, such as ICT networks covered under CISPR standards. Key elements include EMC performance criteria, standardized test conditions, and test set-ups tailored for a broad spectrum of HBES/BACS components.

Key Topics

• EMC Performance Requirements
  IEC 63044-5-1 sets baseline EMC performance thresholds that devices and networks within HBES/BACS must meet to ensure reliable operation under electromagnetic disturbances.

4 General requirements
This document applies in the following way.
– If no applicable EMC product standard exists, the test set-up, test levels and performance
criteria of the IEC 63044 series apply.
– If an applicable EMC product standard does not specify requirements for HBES
applications, the test set-up, test levels and general performance criteria of the IEC 63044
series apply. The specific performance criteria of the product standard apply.
– If a product standard specifies requirements for HBES (see Annex C for examples), the
test levels and general performance criteria of the IEC 63044 series shall be adopted as
the minimum level.
5 Performance criteria
5.1 General performance criteria
During and after all tests, independent of the performance criteria, the device shall not block
the communication among the other HBES devices or send unintended telegrams.
A functional description and a definition of performance criteria, during or as a consequence
of the EMC testing, shall be provided by the manufacturer and noted in the test report, based
on the following criteria.
– Many devices operate using sophisticated protocol services which permit the recovery of
data corrupted by interference or cause re-transmission of data in the event of corruption.
Transmission errors caused by the application of the tests in this document and which are
subsequently corrected by the protocol services are regarded as normal and the
equipment is regarded as operating as intended in such circumstances;
– Changes in stored data, such as communication error logs, and which are not directly
related to the intended function of the equipment shall be ignored, or recorded on request
by the manufacturer.
5.2 Performance criterion A
In addition to the general performance criteria in 5.1, the device shall continue to operate
according to its product documentation as intended during and after the test. No unintended
change of state, stored data directly related to the intended function, unintended or loss of
function is allowed.
During the test, audio and/or video signals may be corrupted during the test, providing the
information is kept intelligible to a qualitative evaluation.

5.3 Performance criterion B
In addition to the general performance criteria in 5.1, the device shall continue to operate
according to its product documentation as intended after the test. Unintended change of state,
stored data directly related to the intended function, unintended function or loss of function is
not allowed after the test.
The measurement conditions shall be defined by the manufacturer. During the test,
degradation of performance is allowed as follows.
– For analogue I/O signal ports, degradation up to 10 times the tolerance specified in
product documentation, with a maximum value of 50 % of full scale, is allowed.
– For digital I/O signal ports, no unexpected change of state or stored data related to the
intended function is allowed.
– For HBES/BACS network port, degradation of performance is allowed, but not loss of
communication for longer than 1 min.
5.4 Performance criterion C
In addition to the general performance criteria in 5.1, temporary loss of function is allowed,
provided the function is self-recoverable or can be restored by the operation of the controls.
6 Standard test conditions
6.1 General
EMC tests are carried out on a single device (EUT).
All tests shall be done with a minimum test configuration. A minimum test configuration is a
set of devices to exercise the fundamental functions of the EUT.
The minimum test configuration adopted for the EUT shall be recorded on the test report.
Examples of test set ups are provided in Annex B.
The minimum test configuration may be different for each test.
Precautions should be taken to prevent auxiliary devices from being disturbed by tests.
In addition:
– Where a relevant International product Standard (IEC) exists, which defines suitable
operating condition(s) during EMC tests, the operating condition(s) of the EUT, during the
test conditioning, shall be as defined in that Standard.
– Where no relevant International product Standard (IEC) exists, the operating condition(s)
of the EUT, during the test conditioning, shall include at least that (those) corresponding
to the main functional mode (appropriate to the test being undertaken) of the system which
it forms part of.
The configuration and mode(s) of operation during the tests shall be precisely noted in the
test report.
– The use of dedicated software for testing purposes is allowed, providing that all significant
functions are exercised.
– All I/O signal and HBES/BACS network ports shall be tested, with cables attached. If the
EUT has more than five identical ports then at least 10 % of them, with a minimum of five,
shall be tested with cables attached.
NOTE The term “identical” means same hardware and software characteristics.

– 12 – IEC 63044-5-1:2017 © IEC 2017
– Ports (e.g. test and service ports) to which cables are normally not attached need no
cables attached and need not be tested.
– Cable types (e.g. screened, unscreened, twisted pair) shall be those specified by the
manufacturer. If the manufacturer does not specify the cable types in product
documentation, unshielded non-twisted cables shall be used.
– Extensible cables (such as handset cable) shall not be intentionally stretched during the
test. For such cables, the reference length refers to unstretched conditions.
– If the device is required to be installed in a specific case or cabinet according to
manufacturer’s product documentation, all tests on the EUT shall be carried out using
such an enclosure.
– If the device can be installed in different kinds of cabinets available on the market, tests
shall be carried out on the EUT without the cabinet to allow repeatability.
– EUT, auxiliary equipment and cables shall be kept in fixed positions (e.g. by means of
mechanical constraints) during the test.
– A description of the test set-up shall be contained in the test report.
– The cable type shall be referenced in the test report.
6.2 Immunity
6.2.1 Electrostatic discharge (ESD)
This test shall be performed according to the test set-up and test procedures defined in
IEC 61000-4-2, taking into account the general standard test conditions defined in 6.1, by
applying 10 positive and 10 negative discharges in the following manner:
– contact discharge to the conductive surfaces and to coupling planes;
– air discharge at insulating surfaces, if applicable.
Test points shall include hand commands (push buttons, keyboards, etc.), display, touch
screen, slits.
The static electricity discharges shall be applied only to such points and surfaces of the EUT
which are accessible in normal use.
A clear identification of the tested points shall be included in the test report.
Wall-mounted equipment shall be treated as table-top equipment. In order to perform the test,
the wall side of the EUT is turned towards the HCP.
The cable length between the components of the minimum configuration should be 1 m unless
otherwise specified by the manufacturer.
6.2.2 RF fields
The test shall be performed according to IEC 61000-4-3, taking into account the general
standard test conditions defined in 6.1.
Wall-mounted equipment shall be treated as table-top equipment.
EUT with each side dimension below 5 cm shall be tested on front face only with vertical and
horizontal polarization.
Cables shall run either vertically or horizontally in the field uniform area, for at least 1 m.
Connection with AE outside the chamber shall be released through a bypass filter with no
effects on signal transmission.

6.2.3 Fast transients (bursts)
This test shall be performed according to IEC 61000-4-4, taking into account the general
standard test conditions defined in 6.1.
Additional information on test set up is given in Annex A
For tests with the EMC coupling clamp, multiconductor cables shall be tested as a single
cable.
6.2.4 Surge
This test shall be performed according to IEC 61000-4-5, taking into account the general
standard test conditions defined in 6.1.

For communication systems with floating (not connected to ground) devices of small sizes, it
is important to consider the return path for the surge current to the test equipment.
In order to specify a reproducible return path to ground, an impedance Z (R = 50 Ω,
C = 0,47 µF) or that specified by the manufacturer shall be connected from ground to each
wire of a communication cable. For devices with only point-to-point communication (i.e. only
direct communication between two units), this impedance can be omitted during the test. The
impedance used shall be recorded in the test report.
6.2.5 RF voltage
This test shall be performed according to IEC 61000-4-6, taking into account the general
standard test conditions defined in 6.1.
For tests with the EMC coupling clamp, multiconductor cables shall be tested as a single
cable.
6.2.6 Power frequency magnetic fields
This test shall be performed according to IEC 61000-4-8, taking into account the general
standard test conditions defined in 6.1.
6.2.7 Voltage dips and interruptions
This test shall be performed according to IEC 61000-4-11, taking into account the general
standard test conditions defined in 6.1.
The test shall be done both with a minimum configuration and a fully loaded EUT from the
power supply point of view.
6.3 Emission
6.3.1 General
The configuration of the test sample shall be varied to maximize the emission consistent with
the typical applications."
The EUT shall be tested after the thermal steady-state condition is reached.

6.3.2 Conducted emission
This test shall be performed according to CISPR 22 and CISPR 32, taking into account the
general standard test conditions defined in 6.1.
The EUT shall be tested after the thermal steady-state condition is reached.
6.3.3 Radiated emission
This test shall be performed according to CISPR 22 and CISPR 32, taking into account the
general standard test conditions defined in 6.1.
Cables shall run either vertically or horizontally for at least 1 m. Connection with AE outside
the chamber shall be released through a bypass filter with no effects on signal transmission.
6.3.4 Low frequency emission
This test shall be performed according to IEC 61000-3-2 and IEC 61000-3-3, taking into
account the general standard test conditions defined in 6.1.

Annex A
(informative)
Additional information for fast transients (burst) test set-up
For communication systems with floating devices of small sizes (e.g. sensors or push-buttons)
without connection to earth and supplied via the communication wires or by batteries, it is
important to consider the return path for the burst current to ground plane of the test
equipment.
The basic standard IEC 61000-4-4 specifies the EUT to be placed 10 cm over the ground
plane. However, when mounting the device direct on a wall, this capacity to ground can be
increased because of the smaller coupling distance. This can influence the immunity to the
burst impact. Therefore, an additional test shall be done with the EUT placed directly on the
ground plane.
In cases where the EUT has an accessible metal surface or shielding, the test shall be done
with and without connection of this metal surface or shielding to earth.

Annex B
(informative)
Test set-ups
B.1 General
Annex B gives examples of test set-ups for EMC tests. Real test set-ups should be created
accordingly and described in the test report (see 6.1). These test set-ups are based on
twisted-pair cabled systems. To create test set-ups for power line system and wireless
system, make reference to the relevant product standards.
B.2 Test set-up for conducted immunity tests
The following test set-up is applicable to
– fast transients/burst (IEC 61000-4-4),
– surge (IEC 61000-4-5),
– RF conducted disturbances (IEC 61000-4-6).
The separation between the EUT and the rest of the system (minimum test configuration,
according to 6.1) is normally obtained with a minimum cable length of 3 m. The cable may be
twisted to save space.
To improve separation, a CDN or filter may be used, providing it will not affect the system
communication. If required, this device is connected as reported in Figure B.1, l being the
total length of the cable and the device.

The EUT is fixed on an insulating support, placed at the centre of the uniform field area
(reference volume for emission). At least 1 m of cable is fixed in vertical position in proximity
to the axis of the turntable. The auxiliary part of the system is placed outside the chamber and
connected through a filter. When filtering is not possible (loss of communication), precautions
may be taken to keep the shielding attenuation of the chamber when creating the connection
with the outside.
The horizontal path of the cable is laid on the floor to minimize its influence on both immunity
and emission.
The final path from the floor to the chamber outlet is kept as short as possible, vertical and
close to the wall absorbers.
Precautions may be taken to prevent any movement of the cable when the EUT turns.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.

Part 5-1: EMC requirements, conditions and test set-up

1 Scope
This part of IEC 63044 is a product family standard that sets the minimum level of EMC
performance for the HBES/BACS network in addition to the product EMC standards for
HBES/BACS devices.
It also applies to devices used within an HBES/BACS network for which no specific
HBES/BACS product EMC standard exists.
This product family standard specifies the EMC requirements for HBES/BACS devices.
In addition, it defines EMC requirements for the interface of equipment intended to be
connected to an HBES/BACS network. It does not apply to interfaces to other networks.
NOTE An example of other networks is a dedicated ICT network covered by CISPR 22 and 23 CISPR 32.
This document provides general performance requirements, standard test conditions and test
set-ups.
This document is applicable (but not limited) to
– operator stations and other human–system interface devices,
– devices for management functions,
– control devices, automation stations and application-specific controllers,
– field devices and their interfaces,
– cabling and interconnection of devices,
used within a dedicated HBES/BACS network.

5 Performance criteria
5.1 General performance criteria
During and after all tests, independent of the performance criteria, the device shall not block
the communication among the other HBES devices or send unintended telegrams.
A functional description and a definition of performance criteria, during or as a consequence
of the EMC testing, shall be provided by the manufacturer based on intended use and noted
in the test report, based on the following criteria.
– Many devices operate using sophisticated protocol services which permit the recovery of
data corrupted by interference or cause re-transmission of data in the event of corruption.
Transmission errors caused by the application of the tests in this document and which are
subsequently corrected by the protocol services are regarded as normal and the
equipment is regarded as operating as intended in such circumstances;
– Changes in stored data, such as communication error logs, and which are not directly
related to the intended function of the equipment shall be ignored, or recorded on request
by the manufacturer.
5.2 Specific performance criteria
5.25.2.1 Performance criterion A
In addition to the general performance criteria in 5.1, the device shall continue to operate
according to its product documentation as intended during and after the test. No unintended
change of state, stored data directly related to the intended function, unintended or loss of
function is allowed.
During the test, audio and/or video signals may be corrupted during the test, providing the
information is kept intelligible to a qualitative evaluation.
5.35.2.2 Performance criterion B
In addition to the general performance criteria in 5.1, the device shall continue to operate
according to its product documentation as intended after the test. Unintended change of state,
stored data directly related to the intended function, unintended function or loss of function is
not allowed after the test.
The measurement conditions shall be defined by the manufacturer. During the test,
degradation of performance is allowed as follows.
– For analogue I/O signal ports, degradation up to 10 times the tolerance specified in
product documentation, with a maximum value of 50 % of full scale, is allowed.
– For digital I/O signal ports, no unexpected change of state or stored data related to the
intended function is allowed.
– For HBES/BACS network port, degradation of performance is allowed, but not loss of
communication for longer than 1 min. Loss of communication is allowed during the
application time of the disturbance but the communication shall be restored after
application of the disturbance has stopped.
5.45.2.3 Performance criterion C
In addition to the general performance criteria in 5.1, temporary loss of function is allowed,
provided the function is self-recoverable or can be restored by the operation of the controls.

6 Standard test conditions
6.1 General
EMC tests are carried out on a one single device (EUT).
All tests shall be done with a minimum test configuration. A minimum test configuration is a
set of devices to exercise the fundamental functions of the EUT.
The minimum test configuration adopted for the EUT shall be recorded on the test report.
Examples of test set ups are provided in Annex B.
The minimum test configuration may be different for each test.
Precautions should be taken to prevent auxiliary devices from being disturbed by tests.
In addition:
– Where a relevant International product Standard (IEC) exists, which defines suitable
operating condition(s) during EMC tests, the operating condition(s) of the EUT, during the
test conditioning, shall be as defined in that Standard.
– Where no relevant International product Standard (IEC) exists, the operating condition(s)
of the EUT, during the test conditioning, shall include at least that (those) corresponding
to the main functional mode (appropriate to the test being undertaken) of the system which
it forms part of.
The configuration and mode(s) of operation during the tests shall be precisely noted in the
test report.
– The use of dedicated software for testing purposes is allowed, providing that all significant
functions are exercised.
– All I/O signal and HBES/BACS network ports shall be tested, with cables attached. If the
EUT has more than five identical ports then at least 10 % of them, with a minimum of five,
shall be tested with cables attached.
NOTE The term “identical” means same hardware and software characteristics.
– Ports (e.g. test and service ports) to which cables are normally not attached need no
cables attached and need not be tested.
– Cable types (e.g. screened, unscreened, twisted pair) shall be those specified by the
manufacturer. If the manufacturer does not specify the cable types in product
documentation, unshielded non-twisted cables shall be used.
– Extensible cables (such as handset cable) shall not be intentionally stretched during the
test. For such cables, the reference length refers to unstretched conditions.
– If the device is required to be installed in a specific case or cabinet according to
manufacturer’s product documentation, all tests on the EUT shall be carried out using
such an enclosure.
– If the device can be installed in different kinds of cabinets available on the market, tests
shall be carried out on the EUT without the cabinet to allow repeatability.
– EUT, auxiliary equipment and cables shall be kept in fixed positions (e.g. by means of
mechanical constraints) during the test.
– A description of the test set-up shall be contained in the test report.
– The cable type shall be referenced in the test report.

– 14 – IEC 63044-5-1:2017+AMD1:2022 CSV
© IEC 2022
Time between pulses: 1 min or less.
For communication systems with floating (not connected to ground) devices of small sizes, it
is important to consider the return path for the surge current to the test equipment.
In order to specify a reproducible return path to ground, an impedance Z (R = 50 Ω,
C = 0,47 µF) or that specified by the manufacturer shall be connected from ground to each
wire of a communication cable. For devices with only point-to-point communication (i.e. only
direct communication between two units), this impedance can be omitted during the test. The
impedance used shall be recorded in the test report.
6.2.5 RF voltage
This test shall be performed according to IEC 61000-4-6, taking into account the general
standard test conditions defined in 6.1.
For tests with the EMC coupling clamp, multiconductor cables shall be tested as a single
cable.

general standard test conditions defined in 6.1.
The EUT shall be tested after the thermal steady-state condition is reached.
6.3.3 Radiated emission
This test shall be performed according to CISPR 22 and CISPR 32, taking into account the
general standard test conditions defined in 6.1.
Cables shall run either vertically or horizontally for at least 1 m. Connection with AE outside
the chamber shall be released through a bypass filter with no effects on signal transmission.

© IEC 2022
6.3.4 Low frequency emission
This test shall be performed according to IEC 61000-3-2 and IEC 61000-3-3, taking into
account the general standard test conditions defined in 6.1.

Annex A
(informative)
Additional information for fast transients (burst) test set-up
For communication systems with floating devices of small sizes (e.g. sensors or push-buttons)
without connection to earth and supplied via the communication wires or by batteries, it is
important to consider the return path for the burst current to ground plane of the test
equipment.
The basic standard IEC 61000-4-4 specifies the EUT to be placed 10 cm over the ground
plane. However, when mounting the device direct on a wall, this capacity to ground can be
increased because of the smaller coupling distance. This can influence the immunity to the
burst impact. Therefore, an additional test shall be done with the EUT placed directly on the
ground plane.
In cases where the EUT has an accessible metal surface or shielding, the test shall be done
with and without connection of this metal surface or shielding to earth.

Annex B
(informative)
Test set-ups
B.1 General
Annex B gives examples of test set-ups for EMC tests. Real test set-ups should be created
accordingly and described in the test report (see 6.1). These test set-ups are based on
twisted-pair cabled systems. To create test set-ups for power line system and wireless
system, make reference to the relevant product standards.
B.2 Test set-up for conducted immunity tests
The following test set-up is applicable to
– fast transients/burst (IEC 61000-4-4),
– surge (IEC 61000-4-5),
– RF conducted disturbances (IEC 61000-4-6).
The separation between the EUT and the rest of the system (minimum test configuration,
according to 6.1) is normally obtained with a minimum cable length of 3 m. The cable may be
twisted to save space.
To improve separation, a CDN or filter may be used, providing it will not affect the system
communication. If required, this device is connected as reported in Figure B.1, l being the
total length of the cable and the device.

Figure B.2 – Set-up for radiated tests
The EUT is fixed on an insulating support, placed at the centre of the uniform field area
(reference volume for emission). At least 1 m of cable is fixed in vertical position in proximity
to the axis of the turntable. The auxiliary part of the system is placed outside the chamber and
connected through a filter. When filtering is not possible (loss of communication), precautions
may be taken to keep the shielding attenuation of the chamber when creating the connection
with the outside.
The horizontal path of the cable is laid on the floor to minimize its influence on both immunity
and emission.
The final path from the floor to the chamber outlet is kept as short as possible, vertical and
close to the wall absorbers.
Precautions may be taken to prevent any movement of the cable when the EUT turns.
