5.1 General
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;

– 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

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:

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.

Table 4
Replace Table 4 with the following:
Table 4 – Test observation period
Type of equipment behaviour Observation period

Quasi-stationary T of sufficient duration, so that it can be expected to meet the

obs
recommendations for repeatability in 6.3.3.1

Short cyclic (T ≤ 2,5 min) T ≥ 10 cycles (reference method) or T of sufficient duration or

cycle obs obs
synchronization, so that it can be expected to meet the recommendations for
repeatability in 6.3.3.1
Random T of sufficient duration, so that it can be expected to meet the
obs
recommendations for repeatability in 6.3.3.1

Long cyclic (T > 2,5 min) Full equipment program cycle (reference method) or a representative 2,5 min

cycle
period expected to be the operating period with the highest THC

'Synchronization' means that the total observation period is sufficiently close to including an exact integral

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
