IEC 61000-3-2:2005

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

Deals with the limitation of harmonic currents injected into the public supply system. 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 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.

Compatibilité électromagnétique (CEM) - Partie 3-2: Limites - Limites pour les émissions de courant harmonique (courant appelé par les appareils ≤ 16 A par phase)

Traite de la limitation des courants harmoniques injectés dans le réseau public d'alimentation. Définit les limites des harmoniques du courant d'entrée qui peuvent être produits par les matériels soumis à l'essai dans des conditions spécifiées. Les harmoniques sont mesurés conformément aux dispositions des annexes A et B. Cette partie de la CEI 61000 est applicable aux appareils électriques et électroniques ayant un courant d'entrée dont la valeur est inférieure ou égale à 16 A par phase et qui sont destinés à être raccordés à des réseaux publics de distribution à basse tension. Les appareils de soudage à l'arc qui ne sont pas du matériel professionnel, dont le courant d'entrée est inférieur ou égal à 16 A par phase, sont inclus dans le domaine d'application de la présente norme. Les appareils de soudage à l'arc destinés à un usage professionnel, tels que spécifiés dans la CEI 60974-1, sont exclus du domaine d'application de la présente norme et peuvent être sujets à des restrictions d'installation comme indiqué dans la CEI 61000-3-4 ou la CEI 61000-3-12. Les essais effectués conformément à la présente norme sont des essais de type. Les conditions d'essais pour des appareils particuliers sont indiquées à l'annexe C.

CORRIGENDUM 1
NOTE This corrigendum relates only to the consolidated edition IEC 61000-3-2:2009 (Edition 3.2). The third
edition of IEC 61000-3-2 (2005) and its Amendment 1 (2008) and Amendment 2 (2009) are not affected. In
Subclause 7.3 b) the two dashed items are shifted to the right and the last sentence is reinserted.

7.3 Limits for Class C equipment
Instead of:
b) Active input power ≤25 W
Discharge lighting equipment having an active input power smaller than or equal to 25 W
shall comply with one of the following two sets of requirements:
– the harmonic currents shall not exceed the power-related limits of Table 3, column 2, or:
– the third harmonic current, expressed as a percentage of the fundamental current, shall
not exceed 86 % and the fifth harmonic current shall not exceed 61 %. Also, the waveform
of the input current shall be such that it reaches the 5 % current threshold before or at 60º,
has its peak value before or at 65º and does not fall below the 5 % current threshold
before 90º, referenced to any zero crossing of the fundamental supply voltage. The
current threshold is 5 % of the highest absolute peak value that occurs in the
measurement window, and the phase angle measurements are made on the cycle that
includes this absolute peak value. See Figure 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 third edition of IEC 61000-3-2 cancels and replaces the second edition published in 2000,
