36、SION _ SPECIFICATION FOR RADIO DISTURBANCE AND IMMUNITY MEASURING APPARATUS AND METHODS Part 4-2: Uncertainties, statistics and limit modelling Measurement instrumentation uncertainty FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comp
37、rising 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 Stan
38、dards, 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 prep
39、aratory 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 organi
40、zations. 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 o
41、f 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 misinterpretatio
42、n 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 regio
43、nal publication shall be clearly indicated in the 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 b
44、y independent certification bodies. 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 f
45、or 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 No
46、rmative 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 res
47、ponsible for identifying any or all such patent rights. International Standard CISPR 16-4-2 has been prepared by CISPR subcommittee A: Radio-interference measurements and statistical methods. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical rev
48、ision. This edition includes the following significant technical additions with respect to the previous edition: Methods of conducted disturbance measurements on the mains port using a voltage probe, on the telecommunication port using an AAN (ISN), CISPR 16-4-2 IEC:2011 5 on the telecommunication p
49、ort using a CVP, and on the telecommunication port using a current probe. Methods of radiated disturbance measurements in the frequency range 30 MHz to 1 000 MHz using a FAR, and in the frequency range 1 GHz to 18 GHz using a FAR. This publication has the status of a basic EMC standard in accordance with IEC Guide 107:2009, Electromagnetic compatibility Guide
