Connectors for electronic equipment - Tests and measurements -- Part 23-7: Screening and filtering tests - Test 23g: Effective transfer impedance of connectors

Defines a test method intended to assess the screening effectiveness of screened non-circular multi-pole, electrically short, connectors by the measurement of the effective (surface) transfer impedance, using a network analyzer, for frequencies up to 1 GHz. Is based on the line injection test method.

Connecteurs pour équipements électroniques - Essais et mesures -- Partie 23-7: Essais d'écrantage et de filtrage - Essai 23g: Impédance de transfert efficace des connecteurs

Définit une méthode d'essai destinée à évaluer l'efficacité de l'écrantage des connecteurs écrantés non circulaires multi-pôles, électriquement courts par la mesure de l'impédance de transfert (de surface) efficace, au moyen d'un analyseur de réseaux, pour des fréquences jusqu'à 1 GHz. Est fondée sur la méthode d'essai par injection de ligne.

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 IEC 60512-23-7 has been prepared by subcommittee 48B:

Connectors, of IEC technical committee 48: Electromechanical components and mechanical

structures for electronic equipment.
The text of this standard is based on the following documents:
FDIS Report on voting

1 Scope and object

This part of IEC 60512-23 defines a test method which is intended to assess the screening

effectiveness of screened non-circular multi-pole, electrically short, connectors by the

measurement of the effective (surface) transfer impedance Z expressed in Ω, using a

network analyzer, for frequencies up to 1 GHz. It is based on the line injection test method

according IEC 61196-1 with a specific type of injection wire, which is adapted to the shapes

of connectors. Due to the specific test set-up used in the method described hereinafter the

connector screen itself is not verified, but the combination of two connectors (male and

female) together, i.e. the test results include the effectiveness of the screens of the two

connectors and the joint between the connectors and the joints of the cable to the connector.
