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.
9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 2 to IEC 61000-3-3:2013 has been prepared by subcommittee 77A: EMC – Low
frequency phenomena, of IEC technical committee 77:Electromagnetic compatibility.
The text of this Amendment is based on the following documents:
CDV Report on voting
77A/1075/CDV 77A/1093/RVC
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this Amendment is English.

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications/.
A list of all parts in the IEC 61000 series, published under the general title Electromagnetic
compatibility (EMC), can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
The contents of the corrigendum 1 (2022-01) have been included in this copy.

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.
lt
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
lt
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.
st
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.

lt
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
