No. Date Text affected BRITISH STANDARD PD CISPR/TR 16-2-5:2008 The UK Committee is concerned that the wording in the Note in Subclause 4.4 restricts the application of the far field formula. I

6、n its opinion it does not take account of the possible large size of the equipment under test (EUT), and so could allow inaccurate extrapolation using the formula. The UK Committee considers that, as well as the scenario outlined in the Note in Subclause 4.4, another scenario is also feasible when a

7、pplying equation (1) where, for large-size EUTs, equation (1) is only applicable if Dmeas is in the far field. This is the region where the relative distance from the centre and edge of the EUT causes a phase difference of less than pi/8 radians (22.5 degrees). This boundary is at the Rayleigh Dista

8、nce. In this case Equation (1) should only be applied if Dmeas 2Dsource2 / lambda where; Dsource = largest dimension in metres between synchronous noise sources within the EUT as seen from the measuring point. lambda = wavelength = 300/ megahertz For each EUT the value of Dsource is to be determined

9、 by the test authority and justified in the test report. When only a small dimension Dsource is identified, the value used in the above equation should be Dsource =0.28 * lambda. The choice of this dimension (= lambda/(2* root(pi) ) will ensure that measurement is only made in the region where the f

10、ar field component exceeds the reactive near field, i.e. Dmeas is greater than lambda/(2*pi). ly 1 Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 28/10/2009 02:47, Uncontrolled Copy, (c) BSI CISPR/TR 16-2-5 Edition 1.0 2008-07 TECHNICAL REPORT Specification for radio disturbance and immunity

17、E ON RADIO INTERFERENCE _ SPECIFICATION FOR RADIO DISTURBANCE AND IMMUNITY MEASURING APPARATUS AND METHODS Part 2-5: In situ measurements of disturbing emissions produced by physically large equipment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for sta

18、ndardization 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 I

19、nternational 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 partici

20、pate 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 betw

21、een 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 Publicatio

22、ns 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 an

23、y 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

24、 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 ed

25、ition 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 d

26、irect 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 indispe

27、nsable 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. The main task of IEC technical comm

28、ittees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. CISPR 16-2-5, which is a t

29、echnical report, has been prepared by CISPR subcommittee H: Limits for the protection of radio services.

30、 following documents: Enquiry draft Report on voting CISPR/H/161/DTR CISPR/H/172/RVC 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

31、. A list of all parts of the CISPR 16 series, published under the general title Specification for radio disturbance and immunity measuring apparatus and methods, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenan

32、ce 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 amended. A bilingual version of this publication may be issued at a later date.

34、 physically large equipment 1 Scope This part of CISPR 16 deals with in situ electromagnetic disturbance measurements in any environment from physically large equipment and systems excluding networks. It covers both radiated and conducted emission phenomena, and does not deal with immunity tests. Th

35、is technical report is intended to be applied primarily to such physically large equipment which are not under the scope of any existing emission standards (as for example CISPR 11 and CISPR 22). It serves only as a guideline on how to deal with emissions of that equipment at the particular location

36、 of installation. It does not establish any emission requirements. NOTE 1 Although this technical report is intended to be applied to equipment which is not under the scope of any existing emission standards, it may be used also in such cases in order to serve as additional information for carrying

37、out in situ measurements for any type of large equipment. NOTE 2 Examples of large equipment are: production machines, conveyors, large displays, aircraft simulators, traffic control equipment, etc. Due to the severe impact of the conditions existing at a particular location of operation and the use

38、 of the respective large equipment, however, it is not intended to use the measurements in the frame of type testing. NOTE 3 In general, type testing on large equipment is only possible at standardized test sites in a controlled environment. The assessment results obtained under in situ conditions a

39、re only valid for the respective individual large equipment actually measured at its particular place of installation. These results cannot be transposed to other equipment of the same type, but installed at other locations. Reference in-situ measurement distances will be given. This allows comparis

40、on of the measurement results with limits from existing relevant standards. The frequency range under consideration is from 9 kHz to 18 GHz. Dealing with biological effects on living matter is excluded from this document. 2 Normative references The following referenced documents are indispensable fo
