IEC 62153-4-16:2021

Metallic cables and other passive components test methods - Part 4-16: Electromagnetic compatibility (EMC) - Extension of the frequency range to higher frequencies for transfer impedance and to lower frequencies for screening attenuation measurements using the triaxial set-up

IEC 62153-4-16:2021 specifies a method to extrapolate the test results of transfer impedance to higher frequencies and the test results of screening attenuation to lower frequencies when measured with the triaxial set-up in accordance with IEC 62153-4-3, IEC 62153‑4‑4 and IEC 62153-4-15. This method is applicable for homogenous screens, i.e. screens having a transfer impedance directly proportional to length.
This second edition cancels and replaces the first edition published in 2016. This edition includes the following significant technical changes with respect to the previous edition:
- replacement of the conversion formula which was limited to a matched DUT by a new conversion formula suitable for any load conditions.
The contents of the corrigendum of Novembre 2023 have been included in this copy.

Méthodes d'essai des câbles métalliques et autres composants passifs - Partie 4-16: Compatibilité électromagnétique (CEM) - Extension de la plage de fréquences à des fréquences supérieures pour l'impédance de transfert et à des fréquences inférieures pour mesurer l'affaiblissement d'écran à l'aide d'un montage triaxial

IEC 62153-4-16:2021 décrit une méthode d'extrapolation des résultats d'essai de l'impédance de transfert à des fréquences supérieures et des résultats d'essai de l'affaiblissement d'écran à des fréquences inférieures mesurées à l'aide d'un montage triaxial selon l'IEC 62153-4-3, l’IEC 62153-4-4 [1] et l'IEC 62153-4-15, respectivement. Cette méthode s'applique aux écrans homogènes, c'est-à-dire aux écrans dont l'impédance de transfert est directement proportionnelle à la longueur.
Cette deuxième édition annule et remplace la première édition parue en 2016.Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Remplacement de la formule de conversion, qui était limitée à un DUT adapté, par une nouvelle formule correspondant à toutes les conditions de charge.
Le contenu du corrigendum de novembre 2023 a été pris en considération dans cet exemplaire.

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 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 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.
IEC 62153-4-16 has been prepared by IEC technical committee 46: Cables, wires,
