Metallic cables and other passive components test methods - Part 4-15: Electromagnetic compatibility (EMC) - Test method for measuring transfer impedance and screening attenuation - or coupling attenuation with triaxial cell (IEC 62153-4-15:2021)

This part of IEC 62153 specifies the procedures for measuring with triaxial cell the transfer
impedance, screening attenuation or the coupling attenuation of connectors, cable assemblies
and components, for example accessories for analogue and digital transmission systems, and
equipment for communication networks and cabling.
Measurements can be achieved by applying the device under test directly to the triaxial cell or
with the tube-in-tube method in accordance with IEC 62153-4-7.

IEC 62153-4-15:2021 est disponible sous forme de IEC 62153-4-15:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62153-4-15:2021 spécifie les procédures de mesure de l’impédance de transfert, de l’affaiblissement d'écran ou de couplage des connecteurs, des cordons et des composants, par exemple les accessoires pour les systèmes de transmission numérique et analogique, et les équipements de réseaux de communication et de câblage, avec une cellule triaxiale. Cette deuxième édition annule et remplace la première édition parue en 2015. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) le mesurage de l’affaiblissement de couplage des connecteurs, cordons et composants symétriques avec ou sans symétriseur a été ajouté; b) l’application d’un adaptateur d’essai a été ajoutée; c) application d’un plan de court-circuit amovible; d) application de la cellule "absorbeuse" triaxiale; e) correction des résultats d'essai dans le cas où l’impédance d’entrée durécepteur R est supérieure à l’impédance caractéristique du circuit externe Z2.

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.

International Standard IEC 62153-4-15 has been prepared by IEC technical committee 46:

Cables, wires, waveguides, R.F. connectors, R.F. and microwave passive components and

accessories.

This second edition cancels and replaces the first edition published in 2015. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) measurement of coupling attenuation of balanced connectors, assemblies and components

with balun and balunless added;
b) application of a test adapter was added;
c) application of a moveable shorting plane;
---------------------- Page: 11 ----------------------

d) application of the triaxial "absorber" cell;

e) correction of test results in the case that the receiver input impedance R is higher than the

characteristic impedance of the outer circuit Z .
The text of this International Standard is based on the following documents:
FDIS Report on voting
46/814/FDIS 46/822/RVD

Full information on the voting for its approval can be found in the report on voting indicated in

the above table.
The language used for the development of this International Standard is English.

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in

accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available

at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are

described in greater detail at www.iec.ch/standardsdev/publications.

A list of all the parts in the IEC 62153-4 series, published under the general title Metallic

communication cable test methods – Electromagnetic compatibility (EMC), can be found on the

IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under webstore.iec.ch in the data related to the

specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates that it

contains colours which are considered to be useful for the correct understanding of its

contents. Users should therefore print this document using a colour printer.
