EN 55016-4-2:2004

Specification for radio disturbance and immunity measuring apparatus and methods - Part 4-2: Uncertainties, statistics and limit modelling - Uncertainty in EMC measurements

This part of CISPR 16 is designated a basic standard, which specifies the manner in which measurement uncertainty is to be taken in to account in determining compliance with CISPR limits. The material is also relevant to any EMC test when interpretation of the results and conclusions reached will be impacted by the uncertainty of the instrumentation used during the testing. Annex A contains the background material used in providing the amount of measurement uncertainty found in generating the CISPR values shown in Clause 4 and hence provides valuable background material for those needing both initial and further information on measurement uncertainty and how to take into account individual uncertainties in the measurement chain. The annex however is not intended to be a tutorial of user manual or to be copied when making uncertainty calculations. CISPR 16-1, CISPR 16-2, CISPR 16-3 and CISPR 16-4 have been reorganised into 14 parts, to accommodate growth and easier maintenance. This first edition of CISPR 16-4-2 cancels and replaces the first edition of CISPR 16-4 published in 2002. It contains the clauses of CISPR 16-4 without technical changes.

Spécifications des méthodes et des appareils de mesure des perturbations radioélectriques et de l'immunité aux perturbations radioélectriques - Partie 4-2: Incertitudes, statistiques et modélisation des limites - Incertitudes de mesure CEM

La présente partie de la CISPR 16 est une norme fondamentale qui spécifie la manière dont il faut prendre en compte les incertitudes de mesure lors de la détermination de la conformité aux limites du CISPR. Cela s'applique également à tous les essais CEM lorsque les interprétations des résultats et les conclusions peuvent être influencées par l'incertitude de l'instrumentation utilisée pendant les essais. L'annexe A contient les informations utilisées pour fournir la valeur de l'incertitude de mesure CISPR donnée à l'article 4 et, en conséquence, fournit des informations importantes pour ceux qui ont besoin à la fois de l'information initiale et de l'information complémentaire sur les incertitudes de mesure et sur la façon de prendre en compte les incertitudes individuelles dans la chaîne de mesure. Toutefois, l'annexe A n'est pas destinée à être un modèle de manuel d'utilisateur ou à être recopiée lors des calculs d'incertitude. Les publications CISPR 16-1, CISPR 16-2, CISPR 16-3 and CISPR 16-4 ont été réorganisées en 14 parties, dans le but de pouvoir gérer plus facilement leur évolution et maintenance. Cette première édition de la CISPR 16-4-2 annule et remplace la CISPR 16-4 publiée en 2002. Elle contient les articles de la CISPR 16-4 sans modifications de leur contenu technique.

FOREWORD
1) The International 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 electronic 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 committees; 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 Standardization (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 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, 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 publications. 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 with 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 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 Normative 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 responsible 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 first edition of CISPR 16-4-2 cancels and replaces the first edition of CISPR 16-4
published in 2002. It contains the clauses of CISPR 16-4 without technical changes.
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
2006. At this date, the publication will be
x reconfirmed;
x withdrawn;
x replaced by a revised edition, or
x amended.
