Metallic communication cable test methods - Part 4-10: Electromagnetic compatibility (EMC) - Transfer impedance and screening attenuation of feed-throughs and electromagnetic gaskets - Double coaxial test method
IEC 62153-4-10:2015 details a coaxial method suitable for determining the transfer impedance and/or screening attenuation of feed-throughs and electromagnetic gaskets. The shielded screening attenuation test set-up according to IEC 62153-4-4 (triaxial method) has been modified to take into account the particularities of feed-throughs and gaskets. This second edition cancels and replaces the first edition published in 2009. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows:
- addition of a new clause that describes a procedure for verification of the measurement set-up and further information regarding sample preparation;
- addition of a new Annex that describes how to improve measurement certainty in the very low frequency area.
Methodes d’essai des cables metalliques de communication - Partie 4-10: Compatibilité électromagnétique (CEM) - Impédance de transfert et affaiblissement d'écran des traversées et des joints d’étanchéité électromagnétiques - Méthode d'essai coaxiale double
L’IEC 62153-4-10:2015 décrit une méthode coaxiale adaptée à la détermination de l’impédance de transfert et/ou de l’affaiblissement d'écran des traversées et des joints d'étanchéité électromagnétiques. Le montage d'essai de l’affaiblissement d'écran blindé selon l’IEC 62153-4-4 (méthode triaxiale) a été modifié afin de prendre en compte les particularités des traversées et des joints d'étanchéité. Cette deuxième édition annule et remplace la première édition parue en 2009. Les modifications techniques majeures par rapport à l’édition précédente sont les suivantes:
- ajout d’un nouvel article qui décrit une procédure de vérification du montage de mesure et des informations supplémentaires relatives à la préparation des échantillons;
- ajout d'une nouvelle Annexe qui décrit comment améliorer la certitude de mesure dans la zone de très basses fréquences.

and screening attenuation of feed-throughs and electromagnetic
gaskets – Double coaxial test method
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.
