Interpretation of the second set of requirements applicable to Class C equipment with a
rated power ≥ 5 W and ≤ 25 W according to 7.4.3 of IEC 61000-3-2:2018 and
Introduction
The second set of requirements of 7.4.3 of IEC 61000-3-2:2018 and
that it reaches the 5 % current threshold before or at 60°, has its peak value before or at 65°
and does not fall below the 5 % current threshold before 90°, referenced to any zero crossing
of the fundamental supply voltage” and that “Components of current with frequencies above
9 kHz shall not influence this evaluation (a filter similar to the one described in 5.3 of
IEC 61000-4-7:2002 and IEC 61000-4-7:2002/AMD1:2008 may be used);”
Testing laboratories and Class C equipment manufacturers concluded that several harmonics
test systems with IEC 61000-4-7 compliant measurement equipment do not completely filter out
the components of current with frequencies above 9 kHz, thus resulting in a non-accurate
evaluation of the phase angles (see Figure 1). One of the reasons why filters are not used is
that they can alter the phase angle itself by introducing a phase delay.
Question
When applying the second set of requirements in 7.4.3, what method shall be used to measure
the phase angle in order to avoid the influence of components of current with frequencies above
9 kHz?
Interpretation
Given the issues reported by test laboratories, if the phase angle is measured with an
IEC 61000-4-7 test system that doesn’t remove the components above 9 kHz correctly, the
measurements with a digital oscilloscope shall prevail, where the components above 9 kHz
have been removed without affecting the phase angle at which the peak current occurs.
NOTE This can be achieved for example by using a synchronous averaging mode of the oscilloscope (see Figure 2).

Annex
Figure 1 and Figure 2 show an incorrect and the correct evaluation of the phase angle.

Replace the first sentence under Class D with the following:
Equipment having a specified power less than or equal to 600 W according to 6.3.2, of the
following types:
5.2 Description of lighting equipment
Replace the existing text with the following:
In this document, lighting equipment as defined in 3.13 includes:
– light sources, lamps, integrated lamps and luminaires;
– the lighting part of multi-function equipment where one of the primary functions of this is
illumination;
– independent lighting control gear;
– ultraviolet (UV) and infrared (IR) radiation equipment;
– illuminated advertising signs;
– independent dimmers, other than phase control types, for lighting equipment;
– DLT control devices.
In this document, lighting equipment as defined in 3.13 excludes:
– lighting devices built in equipment with another primary purpose, such as photocopiers,
overhead projectors and slide projectors, or employed for scale illumination or indication
purposes;
– household appliances whose primary function is not for generating and/or regulating and/or
distributing optical radiation, but which contain one or more light sources with or without a
separate switch (e.g. a range hood with a built-in light source);
– independent phase control dimmers;

– emergency luminaires that emit light only during emergency mode;
– professional appliances whose primary function is to present lighting devices for exhibition
purposes;
– mechanical switches and relays, and other simple devices providing on/off control only, that
do not produce distorted currents.

Add, after 5.2, the following new subclause:
5.3 External power supplies
EPS shall be classified according to the types of equipment they are designated for, as specified
in the instructions for use.
NOTE See also Clause B.17.
6.2 Control methods
Replace the existing text with the following:

© IEC 2020
Asymmetrical controls according to IEC 60050-161:1990, 161-07-12, and half-wave rectification
directly on the mains supply may only be used where:
a) they are the only practical solution permitting the detection of unsafe conditions, or
b) they control an active input power less than or equal to 100 W, or
c) they are operated in a portable equipment fitted with a two-core flexible cord which is
intended for use for a short period of time, i.e. for a few minutes only.
If at least one of these three conditions is fulfilled, half-wave rectification may be used for any
purpose, whereas asymmetrical controls may only be used for the control of motors.
NOTE 1 Equipment which can fulfil condition c) includes, but is not limited to, hair dryers, electrical kitchen
appliances and portable tools.
NOTE 2 When using asymmetrical controls or half-wave rectification under the above circumstances, the input
current has a DC component that can disturb certain types of protection devices in case of an earth fault. See
IEC TR 60755.
Even though asymmetrical controls and half-wave rectification are permitted under the
conditions given above, equipment shall still comply with the harmonic requirements of this
document.
In general, symmetrical controls may be used for any application and without particular
restrictions. However, symmetrical control methods which can produce integer harmonics of the
th
order in the mains input current may be used to control the
mains frequency up to the 40
power supplied to heating elements only if at least one of the following restrictions is met:
• the full sine-wave active input power of these heating elements is lower than or equal to
200 W, or
• the limits of Table 3 are not exceeded when testing with these heating elements active.
Such symmetrical control methods are also allowed for professional equipment provided that
either one of the above conditions is fulfilled, or the relevant emission limits according to
Clause 7 are not exceeded when tested at the supply input terminals and in addition both the
following conditions are fulfilled:
– it is necessary to control precisely the temperature of a heater whose thermal time constant
is less than 2 s, and
– there is no other technique economically available.
Professional equipment whose primary purpose, considered as a whole, is not for heating, shall
be tested against the relevant emission limits according to Clause 7.
NOTE 3 An example of a product whose primary purpose, considered as a whole, is not for heating is a photocopier,
whereas a cooker is considered to have heating as its primary purpose.
For domestic equipment used for a short time (e.g. hair dryers) the above restrictions for
symmetrical control of heating elements shall not apply and the limits for Class A shall apply
instead.
For the application of this document diode rectification is not considered to be a form of control.
6.3.2 Measurement procedure
In the second paragraph replace the first dash with the following:
– for each harmonic order, measure the 1,5 s smoothed RMS harmonic current in each
discrete Fourier transform (DFT) time window as defined in IEC 61000-4-7:2002 and
IEC 61000-4-7:2002 /AMD1:2008;

– 8 – IEC 61000-3-2:2018/AMD1:2020
© IEC 2020
Replace the third paragraph with the following and delete the Note:
The value of the active input power to be used for the calculation of limits shall be determined
as follows:
– measure the 1,5 s smoothed active input power in each DFT time window;
– determine the maximum of the measured values of active input power from the DFT time
windows over the entire duration of the test.
Replace the last paragraph with the following:
For Class C equipment, the fundamental current specified by the manufacturer shall be used
for the calculation of limits. The fundamental component of the current is measured and
specified by the manufacturer in the same way as the power is measured and specified for the
calculation of Class D limits.
6.3.3.1 Repeatability
Replace the text with the following:
The repeatability (see 3.15) of the average value for the individual harmonic currents over the
entire test observation period should be better than ±5 % of the applicable limit, when the
following conditions are met:
– the same equipment under test (EUT) (not another of the same type, but the exact same
specimen);
– the same test system;
– the same location;
– identical test conditions;
– identical climatic conditions, if relevant.
This repeatability recommendation serves the purpose of defining the necessary observation
period (see 6.3.4), but not as a pass/fail criterion for the assessment of compliance with the
requirements of this document.
6.3.3.4 Application of limits
Replace the first paragraph with the following:
The average values for the individual harmonic currents, taken over the entire test observation
period, shall be less than or equal to the applicable limits.
Replace all occurrences of the term “partial odd harmonic current” with “POHC”.
Add at the end of 6.3.3.4 the following sentence:
Details for the calculation of the POHC are defined in Annex C.
6.3.3.5 Test report
Delete, at the end of the existing text, the words “and power factor”.
Add, after 6.4, the following new subclause:

© IEC 2020
6.5 Multifunction equipment
If not otherwise specified in this document, multifunction equipment which has more than one
independent function shall be tested according to the following provisions.
NOTE 1 Independent functions do not intentionally interact with each other.
Multifunction equipment may be tested with each function operated alone if this can be achieved
with reasonable effort. The equipment thus tested complies with the requirements of this
document when each function has satisfied the requirements for the relevant class of equipment
belonging to the function.
For equipment for which it is not obvious how to operate each function alone, the manufacturer
may provide instructions for testing purposes explaining how the function can be operated
alone. These instructions may specify internal changes in the equipment. The equipment shall
be tested accordingly.
If no instruction for testing purposes is provided or if it is not possible to test the equipment with
each function operated alone, the equipment complies with this document, if it meets the most
stringent of the relevant limits with all functions operating simultaneously. However, if one of
the functions can be clearly identified as the main function in comparison with the other
functions, the equipment may be tested with all functions operating simultaneously against the
limits for the main function.
NOTE 2 For example, a refrigerator equipped with a TV on the door still has cooling as the main function.
7.1 General
Delete, in the second paragraph, the fourth dash point "symmetrically controlled heating
elements with a rated power less than or equal to 200 W;"
Replace Note 3 with the following:
NOTE 3 The lower bound for leading edge dimmers and universal phase control dimmers without default mode set
to trailing edge is lower than the lower bound for trailing edge dimmers because the higher order harmonic emissions
of leading edge dimmers are significantly higher when loaded with light sources other than incandescent lamps.
Add the following new paragraph after Note 3:
Limits are not specified for symmetrically controlled heating elements with a controlled active
input power less than or equal to 200 W.
7.4.3 Rated power ≥ 5 W and ≤ 25 W
Replace the last paragraph with the following:
If the lighting equipment includes means for control (e.g. dimming, colour), or is specified to
drive multiple loads, then the measurement is made only at the control setting and at the load
of the light sources that gives the maximum active input power.
Table 2 – Limits for Class C equipment
Replace “30·λ” by “27” (for harmonic order 3).
Replace the text of the existing footnote b with the following:
The limit is determined based on the assumption of modern lighting technologies having power
factors of 0,90 or higher.

number of equipment cycles such that the recommendations for repeatability in 6.3.3.1 are met.

Add, after Clause 7, the following new Clause 8:
8 Compliance with this document
Unless otherwise stated, where this document gives options for evaluating harmonics with a
choice of test methods and associated limits, any one of these options may be used.
The equipment is deemed to comply with this document with respect to the addressed EMC
characteristics when one of the test methods returns a test result compliant with the applicable
requirements.
In any situation where it is necessary to verify the original compliance assessment result, the
option originally chosen shall be used to avoid excessive uncertainties induced by applying
different test methods.

equipment are given in Clauses B.2 to B.17.
B.2.2.1 Input signal
Replace the second and third paragraphs with the following:
The video signal shall be the colour bar signal as defined in IEC 60107-1:1997, 3.2.1.2.
The audio signal shall be a 1 kHz sinusoidal signal.
B.3.1 Conditions
Replace the first paragraph with the following:
Audio amplifiers which draw a supply current which varies less than 15 % of the maximum
current with input signal voltages between zero and a rated source e.m.f. (as defined in
IEC 60268-3:2018) shall be tested with no input signal.
B.3.2 Input signals and loads
Replace the first paragraph and items a) and b) with the following text and renumber Note 1 as
Note:
The following test procedure shall be applied:
a) Connect suitable resistors, equal to the rated load impedance(s), to each amplifier output
for supplying loudspeakers. To monitor the output voltage waveform of the audio amplifier
of a powered loudspeaker, the audio analyser/oscilloscope is connected to internal wiring
at a point representing the electrical output of the amplifier.
NOTE In the case of powered loudspeakers with internal audio amplifiers, the load corresponds to the
loudspeaker and associated crossover network
b) Apply a sinusoidal signal at 1 kHz to a suitable input. For multi-channel amplifiers in which
the surround sound channel amplifiers cannot be alternatively used as a second set of left
and right channel amplifiers, set the controls so that the surround sound channel amplifiers
are supplied with signal at a level 3 dB lower than the signal applied to the left and right
channel.
For products not intended to reproduce 1 kHz signals, a frequency geometrically centred
within the reproducing bandwidth of the amplifier shall be applied.

Replace the second sentence of item f) with the following:
The sinusoidal signal shall be substituted by a pink noise signal of the same RMS voltage,
bandwidth-limited as specified in IEC 60268-1:1985, IEC 60268-1:1985/AMD1:1988 and
IEC 60268-1:1985/AMD2:1988, 6.1.
B.5.2 Lamps
Replace the title and text with the following:
B.5.2 Light sources
Discharge light sources shall be aged for at least 100 h at rated voltage. Discharge light sources
shall be operated for at least 15 min before a series of measurements is made. Some light
sources require a stabilization period exceeding 15 min. Information given in the relevant IEC
performance standard shall be observed.
During ageing, stabilization and measurement, light sources shall be installed as in normal use.
Integrated lamps shall be operated in cap-up position.
B.5.3 Luminaires
Replace the existing text with the following:
Luminaires shall be tested as manufactured and with the included devices. Devices shall be
assembled as stated in the instructions for use.
NOTE 1 Examples of devices to be assembled are light sources and separate lighting control gear.
Luminaires which comprise only passive devices that produce no harmonic currents are deemed
to comply with this document and need not to be tested.
NOTE 2 Examples of passive devices are lamp holders and electromechanical switches.
If the luminaire additionally incorporates further independent functions that do not intentionally
interact with the lighting function and that belong to Class A or Class D, as specified in 5.1, it
may be tested with each independent function operated alone, if this can be achieved without
modifying the luminaire. For luminaires for which it is not obvious how to operate each
independent function alone without modifying the luminaire, the manufacturer may provide an
instruction for testing purposes of how each independent function can be operated alone. This
instruction may specify changes in the luminaire. The luminaire shall be tested accordingly.
The luminaire thus tested complies with the requirements of this document when each
independent function has satisfied the requirements for the relevant class of equipment
belonging to the function. If no instruction for testing purposes is provided or if it is not possible
to test the equipment with each function operated alone, or if further functions belonging to
Class A or Class D intentionally interact with the lighting function, the equipment complies with
this document if it meets the limits for Class C equipment with all functions operating
simultaneously.
NOTE 3 For example, a function can be operated alone by setting the others into an off or standby mode, if provided.
NOTE 4 An example of an independent function is a surveillance camera, which is also active when the light is
switched off.
NOTE 5 An example of a function that intentionally interacts with the lighting function is a motion detector that
controls the light output of the luminaire.

© IEC 2020
If separate tests, as specified in B.5.4, have proved that the included lighting control gear, being
specified and configured for use with the luminaire, complies with the applicable luminaire
requirements and if any included independent devices comply with the specific requirements of
this document, the luminaire is deemed to comply with these requirements and need not be
checked. If this is not the case, the luminaire itself shall be tested and shall comply.
Testing, if required, shall be performed with light sources having electrical characteristics close
to those specified in the instructions for use.
If the luminaire can incorporate more than one light source and/or more types of light sources,
the tests shall be performed for each type of light source when operating the maximum number
of light sources compatible with normal use as specified in the instructions for use.
As an alternative to light sources, artificial loads having electrical characteristics close to those
of the relevant type of light sources may be used.
If the luminaire is equipped with a glow starter, a starter in accordance with IEC 60155:1993
shall be used.
B.5.4 Lighting control gear
Replace the existing text with the following:
Subclause B.5.4 is not applicable to lighting control gear which is tested as part of a luminaire
according to B.5.3.
Lighting control gear shall be tested with the light sources specified in their instructions for use
or with artificial loads having electrical characteristics close to those light sources.
If the lighting control gear is designed for more than one type of light source or if the control
gear is designed to additionally power auxiliary loads (e.g. a sensor or a camera), the
manufacturer shall specify in the instructions for use of the lighting control gear for which load
characteristics (light sources, auxiliary loads) the lighting control gear fulfils the relevant
harmonic requirements and the lighting control gear shall be tested for each corresponding load
characteristic and shall comply in each case.
If the lighting control gear can also be used with a series capacitor, the manufacturer shall
specify in the instructions for use of the control gear for which type of circuit (with or without
series capacitor) the lighting control gear fulfils the harmonic requirements, and the lighting
control gear shall be tested for each corresponding type of circuit and shall comply in each
case.
B.7 Vacuum cleaners
Replace the text with the following:
The air inlet of the vacuum cleaner shall be adjusted according to normal operation as defined
in IEC 60335-2-2:2019.
Vacuum cleaners with variable input power shall be tested in three modes of operation, each
for an identical time interval that is at least 2 min long, with the control adjusted:
– to maximum input power,
– to 50 % ± 5 % of the maximum active input power, or, if that is not possible (e.g. controlled
in steps), to the point closest to 50 % that is supported by the equipment design, and
– to minimum input power.
– 14 – IEC 61000-3-2:2018/AMD1:2020
© IEC 2020
NOTE If the active input power at minimum input power is higher than 50 % of the maximum active input power, the
above requirements imply that the vacuum cleaner is tested for three identical time intervals: one time interval with
the control adjusted to maximum input power and two time intervals with the control adjusted to minimum input power.
These three time intervals need not be consecutive, but the limits according to 6.3.3.4 are
applied as if the intervals were consecutive. In that case, the entire test observation period is
made up of the three identical time intervals, without taking into account harmonic current
values outside these three intervals.
If the vacuum cleaner includes a control to select a temporary high-power ("booster") mode of
operation, which automatically returns to a lower power mode, this high-power mode is not
considered for the calculation of the average values. This mode shall be tested only against the
limits for single 1,5 s smoothed RMS values (see 6.3.3.4).
B.9 Microwave ovens
Replace the text with the following:
The microwave oven shall be tested for a period of 5 min at the maximum power setting. The
EUT shall be operated with a potable water load of initially 1 000 g ± 50 g in a cylindrical
borosilicate glass vessel, having a maximum material thickness of 3 mm and an outside
diameter of approximately 190 mm. The load shall be placed at the centre of the shelf. The
microwave heating shall be switched on 10 s to 15 s before the observation period starts. In
order to prevent a measurement in stand-by mode, the measurement shall be finished before
the microwave oven stops its operation.
B.10.2 Optional conditions for measuring emissions of IT equipment with external
power supplies
Replace the title and text with the following:
B.10.2 IT equipment with external power supplies
For IT equipment with external power supplies, see Clause B.17.
B.13 Kitchen machines as defined in IEC 60335-2-14
Replace the text with the following:
Kitchen machines as listed in the scope of IEC 60335-2-14:2016 are deemed to comply with
the requirements of this document without testing.
B.14 Arc welding equipment which is not professional equipment
Replace the last sentence with the following:
In order to establish the test conditions provided in Clause B.14, the definitions for conventional
load, I , I and U , given in IEC 60974-1:2017 shall be used.

B.17.1 EPS designated for specific models of equipment
The requirements in 17.1 apply to EPS that are designated for specific models of equipment
(e.g. a luminaire made by a specific manufacturer or a kitchen mixer of a certain brand).
These designated EPS shall be tested together with the specific models of equipment using the
test conditions specified for the equipment.
B.17.2 EPS not designated for specific models of equipment
The requirements in 17.2 apply to EPS that are designated for one or more generic types of
equipment (e.g. for a lamp and an appliance) and which are not specified for use with specific
models of equipment (e.g. a luminaire made by a specific manufacturer or a kitchen mixer of a
certain brand).
These EPS shall be tested with loads or artificial loads having characteristics close to the type(s)
of equipment to be powered, as specified in the instructions for use.
The manufacturer or distributor of the EPS shall specify in the instructions for use which types
of equipment it can power. The types of powered equipment shall be consistent with the classes
