AMENDMENT 2
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.

INTRODUCTION to the corrigendum

During the final editing of the text for IEC 61000-3-3:2013/AMD2:2021 (Edition 3), a mistake

occurred and the sentence “P shall not be evaluated” is not displayed as a separate paragraph.

As a result, this could lead to a wrong interpretation of the text and to wrong Pass/Fail results.

This corrigendum is needed to clarify that the text “P shall not be evaluated” applies to all

equipment in Clause A.16.

A.1.6 Microwave ovens
Replace the text of A.1.6 with the following:

The microwave oven 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 load-

carrying surface. The initial temperature of the water shall be between 10 °C and 25 °C.

The tests shall be performed at the lowest power stage, the stage nearest to 50 % of the

maximum power, and a third stage which is the highest adjustable power which is less than or

equal to 90 % of the maximum power. The worst result shall be recorded. The microwave

heating is switched on during the first 10 s of the observation period. For the highest measured

power stage, the microwave heating shall be switched off after 300 s ± 10 s. For the other power

stages, the microwave heating is switched off during the last 10 s of the observation period.

The P shall be evaluated in each case over the required 10 min.
A.5 Test conditions for refrigerators
Replace the title and text of Clause A.5 with the following:
A.5 Test conditions for refrigerators and freezers

Refrigerators shall operate continuously with the door closed. Adjust the thermostat to the mid-

value of the adjusting range. The cabinet shall be empty and not heated. The measurement

shall be made after a steady state has been reached. P and P shall not be evaluated. For

st lt

repeatability reasons, at least three switch-on and three switch-off events of the compressor

shall be evaluated.

Refrigerators with a rated power < 200 W are deemed to comply with all requirements of this

document without testing.
A.10 Test conditions for hairdryers
Replace the title and text of Clause A.10 with the following:
A.10 Test conditions for hairdryers and similar hair care equipment

For hairdryers and similar hair care equipment, which are intended to be held in hand during

use, P shall not be evaluated.

If the EUT is not intended for continuous operation of at least 10 min or switches off

automatically before that time, the minimum time to restart the equipment shall be included in

the observation period. The measurement shall continue until the end of the 10 min interval.

For equipment that can be operated at different settings (e.g. for heat and/or airflow) the power

of the EUT shall be varied by changing the settings during the 10 min observation period as

described below, but without including those settings where the heating is not active.

If the user controls provide discrete settings, all settings shall be included in the observation

period up to a maximum of 10 settings. The maximum and minimum power settings shall be

included.

If the user controls provide instead a range in which the quantity being controlled (e.g. heat)

can be varied continuously between maximum and minimum, the total range shall be divided

---------------------- Page: 6 ----------------------
IEC 61000-3-3:2013/AMD2:2021 – 5 –
© IEC 2021

into 10 equally spaced steps and the corresponding settings shall be used to determine the test

conditions subjected to measurement.

In any case, the 10 min observation time shall include two periods during which the EUT is

switched off. The duration of each off period shall be 1 min. The remaining time (8 min) shall

be equally divided between the available power levels with heating on.

NOTE For example, if a hairdryer provides the user with a combination of 5 settings with heating on, each setting

will be operated for (10-2)/5 = 1,6 min (96 s). Multiple power settings can result from the possible combinations

obtained from multiple settings of heat and airflow.

The initial switch on event and the final switch off event shall be included in the observation

time. The stepping through the different levels is with decreasing heating power, starting from

maximum.
A.14 Test conditions for air conditioners, dehumidifiers, heat pumps, and
commercial refrigerating equipment
Replace the last paragraph with the following:

P and P shall be evaluated using the number of cycles per hour declared by the manufacturer.

st lt
Add the following new Clauses A.16, A.17 and A.18:
A.16 Coffee machines and tea machines

Before the start of a measurement, the machine is warmed up, so that the preparation of

beverages can start immediately after the start of the measurement. To achieve good

repeatability of measurement it is recommended to prepare a typical beverage as warming up

and then wait 30 s before starting the measurements.

For machines designed to prepare only one type of beverage, this beverage shall be prepared

consecutively with an interval of 30 s between two dispensings. This means that at each end of

a beverage, the operator waits 30 s before starting the next beverage.

Any rinsing process during the observation period may be evaluated as a dispensing of a

beverage.

NOTE 1 Some coffee or tea machines automatically activate a rinsing process that is considered part of the normal

dispensing process of the machine.

For machines designed to prepare cups of different beverages, during the 10 min measuring

period for the P the three most typical beverages are prepared one after the other, with the

same interval of 30 s between consecutive dispensings. The preparation of the last beverage

is started, even if it cannot be finished within the measuring period. If the preparation of the

three beverages is finished before the end of the measured period, the cycle of beverages is

continued with the first beverage. The choice of beverages should be based on the

consideration that all internal power loads are at least activated once.
NOTE 2 Typical beverages are for example coffee, cappuccino and tea.

Parameters which can have an influence on the measurement result and can be adjusted by

the operator, are set to the default conditions. For the preparation of cappuccino, water may be

used instead of milk. Hot water may be prepared instead of real tea. The filling temperature of

water is between 10 °C and 25 °C.

For machines, which are designed to prepare exclusively complete pots for a number of cups,

during the 10 min measuring period for the P complete pots are prepared one after the other

with 1 min separation between consecutive pots.
P shall not be evaluated.

In any situation where it is necessary to verify the original measurement the measuring method

originally chosen shall be used in order to ensure consistency of the results.
A.17 Portable fan heaters

Fan heaters shall be evaluated continuously for 120 min. P and P shall be evaluated.

st lt

Fan heaters providing the user with controls to select different heat settings shall be cycled

according to the following steps:
1) one 10 min interval at maximum heat;
2) one 10 min interval off;
3) one 10 min interval at the heat setting expected to give the highest P value;
4) one 10 min interval off:
5) repeat from 1).

NOTE The above steps result in the cycle being run three times (40 × 3 = 120 min).

For equipment that restarts at the latest setting, the operating condition following an off interval

shall be set not later than 10 s after the EUT has been re-started.

For fan heaters which do not provide the user with multiple heat settings (i.e. the heating can

be only on or off), the test conditions evaluation shall be cycled according to the following steps:

a) one interval at maximu
