26、de 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 acti
27、vities, 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
28、 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 deter
29、mined 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 Commit
30、tees. 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
31、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 Publicatio
32、n 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
33、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 natur
34、e 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
35、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. Internationa
36、l Standard IEC 61000-4-2 has been prepared by subcommittee 77B: High- frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility. This second edition cancels and replaces the first edition published in 1995, its amendment 1 (1998) and its amendment 2 (2000) and constitutes a t
37、echnical revision. It forms Part 4-2 of IEC 61000. It has the status of a basic EMC publication in accordance with IEC Guide 107. The main changes with respect to the first edition of this standard and its amendments are the following: the specifications of the target have been extended up to 4 GHz.
38、 An example of target matching these requirements is also provided; SANS 61000-4-2:2009This standard may only be used and printed by approved subscription and freemailing clients of the SABS.61000-4-2 IEC:2008 5 information on radiated fields from human-metal discharge and from ESD generators is pro
39、vided; measurement uncertainty considerations with examples of uncertainty budgets are given too. The text of this standard is based on the following documents: FDIS Report on voting 77B/574/FDIS 77B/584/RVD Full information on the voting for the approval of this standard can be found in the report
40、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 of the IEC 61000 series, published under the general title Electromagnetic compatibility (EMC), can be found on the IEC website. The committee has decided
41、that the contents of this publication will remain unchanged until the maintenance result 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 a
42、mended.

44、ting 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 several parts, published either as inte
45、rnational standards or as technical specifications or technical reports, some of which have already been published as sections. Others will be published with the part number followed by a dash and a second number identifying the subdivision (example: IEC 61000-6-1). This part of IEC 61000 is an Inte
46、rnational Standard which gives immunity requirements and test procedures related to electrostatic discharge.

47、esting and measurement techniques Electrostatic discharge immunity test 1 Scope This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and from personnel to adjacent obj
48、ects. It additionally defines ranges of test levels which relate to different environmental and installation conditions and establishes test procedures. The object of this standard is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment w
49、hen subjected to electrostatic discharges. In addition, it includes electrostatic discharges which may occur from personnel to objects near vital equipment. This standard defines: typical waveform of the discharge current; range of test levels; test equipment; test setup; test procedure; calibration procedure; measurement uncertainty. This standard gives specifications for test performed in “laboratories“ and “p
