18、national 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 elect
19、ronic 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 committee
20、s; 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 Sta
21、ndardization (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
22、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
23、, 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 p
24、ublications. 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 wit
25、h 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 persona
26、l 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 refere
27、nces 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 i
28、dentifying 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,
29、 its amendment 1 (2001) and amendment 2 (2004). 61000-3-2 IEC:2005 9 The text of this standard is based on the second edition, amendment 1, amendment 2 and the following documents: FDIS Report on voting 77A/503/FDIS 77A/516/RVD Full information on the voting for the approval of this standard can be
30、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. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under
31、 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. 61000-3-2 IEC:2005 11 INTRODUCTION IEC 61000 is published in separate parts, according to the following structure: Part 1:
32、General General considerations (introduction, fundamental principles) Definitions, terminology Part 2: Environment Description levels Classification of the environment Compatibility levels Part 3: Limits Emission limits Immunity limits (in so far as they do not fall under the responsibility of the p
33、roduct committees) Part 4: Testing and measurement techniques Measurement techniques Testing techniques Part 5: Installation and mitigation guidelines Installation guidelines Mitigation methods and devices Part 6: Generic standards Part 9: Miscellaneous Each part is further subdivided into sections
34、which are to be published either as international standards, technical specifications, or as technical reports. These standards and reports will be published in chronological order and numbered accordingly (for example, 61000-6-1). This part is an international standard which gives emission limits f
35、or harmonic currents from equipment having an input current up to and including 16 A per phase. This part is a Product Family Standard. 61000-3-2 IEC:2005 13 ELECTROMAGNETIC COMPATIBILITY (EMC) Part 3-2: Limits Limits for harmonic current emissions (equipment input current 16 A per phase) 1 Scope Th
36、is 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 an
37、d 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 6
