29、ILITY (EMC) Part 4-22: Testing and measurement techniques Radiated emissions and immunity measurements in fully anechoic rooms (FARs) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (I
30、EC 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
31、, 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-
32、 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
33、 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 a
34、ccepted 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 interna
35、tional 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
36、 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
37、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
38、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
39、 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 r
40、ights. International Standard IEC 61000-4-22 has been prepared by CISPR subcommittee A: Radio interference measurements and statistical methods, in cooperation with subcommittee 77B: High frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility. This standard has the status
41、of a basic EMC publication in accordance with IEC Guide 107, Electromagnetic compatibility Guide to the drafting of electromagnetic compatibility publications. 61000-4-22 IEC:2010 5 The text of this standard is based on the following documents: Enquiry draft Report on voting CISPR/A/912/FDIS CISPR/A
42、/923/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 of the IEC 61000 series can be found on the IEC websit
43、e under the general title Electromagnetic compatibility (EMC), and of all parts of the CISPR 16 series under the general title Specification for radio disturbance and immunity measuring apparatus and methods. The committee has decided that the contents of this publication will remain unchanged until
44、 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. 6 61000-4-22 IEC:2010 INTRODUCTION This standard is part of the IE
45、C 61000 series of standards, according to the following structure: Part 1: General General considerations (introduction, fundamental principles) Definitions, terminology Part 2: Environment Description of the environment Classification of the environment Compatibility levels Part 3: Limits Emission
46、limits Immunity limits (in so far as they do not fall under the responsibility of the product 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:
47、 Test set-up Part 9: Miscellaneous Each part is further subdivided into several parts, published either as international standards, 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 das
48、h and a second number identifying the subdivision (example: IEC 61000-6-1). This part is an international standard that establishes the required test procedures for using fully anechoic rooms for performing radiated immunity testing and radiated emission measurements. The main text of this standard
49、provides all information that is common to both radiated emission measurements and immunity tests in a FAR (fully anechoic room). This includes the description of a FAR, a common set-up for equipment under test (EUT), and a harmonized validation/calibration procedure. The test methods described in this standard are based on the harmonized validation/calibration which
