ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 3-2: Limits – Limits for harmonic current emissions
(equipment input current ≤ 16 A per phase)

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 IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61000-3-2 has been prepared by sub-committee 77A: Low-
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This fourth edition cancels and replaces the third edition published in 2005, Amendment 1:
2008, Amendment 2:2009 and Corrigendum of August 2009.
This edition includes the following significant technical changes with respect to the previous
edition:
a) a clarification of the repeatability and reproducibility of measurements;
b) a more accurate specification of the general test conditions for information technology
equipment;
c) the addition of optional test conditions for information technology equipment with external
power supplies or battery chargers;

d) the addition of a simplified test method for equipment that undergoes minor changes or
updates;
e) an update of the test conditions for washing machines;
f) a clarification of the requirements for Class C equipment with active input power ≤ 25 W;
g) an update of the test conditions for audio amplifiers;
h) a clarification of the test conditions for lamps;
i) an update of the test conditions for vacuum cleaners;
j) the addition of test conditions for high pressure cleaners;
k) an update of the test conditions for arc welding equipment;
l) the reclassification of refrigerators and freezers with variable-speed drives into Class D;
m) the addition of test conditions for refrigerators and freezers.
The text of this standard is based on the third edition, Amendment 1, Amendment 2, the
Corrigendum of August 2009 and the following documents:
FDIS Report on voting
77A/846/FDIS 77A/853/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 3-2: Limits – Limits for harmonic current emissions
(equipment input current ≤ 16 A per phase)



1 Scope
This part of IEC 61000 deals with the limitation of harmonic currents injected into the public
supply system.
It specifies limits of harmonic components of the input current which may be produced by
equipment tested under specified conditions.
Harmonic components are measured according to Annexes A and B.
This part of IEC 61000 is applicable to electrical and electronic equipment having an input
current up to and including 16 A per phase, and intended to be connected to public low-voltage
distribution systems.
Arc welding equipment which is not professional equipment, with input current up to and
including 16 A per phase, is included in this standard.
Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded
from this standard and may be subject to installation restrictions as indicated in
IEC/TR 61000-3-4 or IEC 61000-3-12.
The tests according to this standard are type tests. Test conditions for particular equipment are
given in Annex C.
For systems with nominal voltages less than 220 V (line-to-neutral), the limits have not yet
been considered.
NOTE The words apparatus, appliance, device and equipment are used throughout this standard. They have the
same meaning for the purpose of this standard.
