Connectors for electrical and electronic equipment - Tests and measurements - Part 23-3: Screening and filtering tests - Test 23c: Shielding effectiveness of connectors and accessories - Line injection method (IEC 60512-23-3:2018)

This part of IEC 60512 defines a standard test method for measuring the shielding
effectiveness SE of a shielded connector, or of a connector not provided with integral shield
once fitted with a shielding accessory and terminated with a screened cable.
The complete assembly has a continuous 360° shielding capability throughout its length.
NOTE 1 Practically, continuous 360° shielding is not always achievable based on the geometry of the connector.
NOTE 2 Shielding” is used in this document with the same meaning as “screening”.
This test method can be applied to shielded connectors and to connector accessories with
shielding capability. The following different connector designs can be tested:
– circular connectors;
– rectangular connectors;
– connectors for printed boards;
– connector shielding accessories.
NOTE 3 For the definition of “accessory” see IEV 581-24-10. A shielding accessory i.e. an accessory that confers
shielding to a non-inherently shielded connector, may be a suitable set of shielded housings providing electrical
continuity, along the mated connector set, between the screen of the (screened) cable at the cable outlet of the
free cable connector housing and the metallic mounting surface for the fixed connector housing. The free connector
housing is provided with a cable screen clamp.
This test method utilizes the principle that the intrinsic shielding property of the connector/
accessory/cable assembly is its surface transfer impedance ZT which can be expressed as the
longitudinal voltage inside the shield, relative to the current flow on the outside shell.
This test method is based on two impedance-matched circuits. See Figure 1 for the
measurement principle. The connector specimen under test is integrated into the secondary
circuit 02. The impedance-matched injection line of the primary circuit 01, which activates
the electromagnetic field, runs parallel to the surface of the specimen under test.
This test is also suitable for measuring the shielding effectiveness of a connector fitted with
triaxial contacts terminated with shielded, twisted pair cables, as used in data bus systems.
NOTE 4 This standard has been adopted by ASD-STAN (formerly known as AECMA) as EN 2591-212 .

IEC 60512-23-3:2018 est disponible sous forme de IEC 60512-23-3:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 60512-23-3:2019. définit une méthode d’essai normalisée pour mesurer l’efficacité de blindage SE d’un connecteur blindé, ou d’un connecteur sans blindage intégré et équipé d’un accessoire de blindage, et raccordé à un câble écranté. Le câble assemblé présente un blindage continu sur 360° sur toute sa longueur. La présente méthode d’essai peut être appliquée aux connecteurs blindés et aux accessoires de connecteur ayant un blindage. Les différentes conceptions de connecteur ci-après peuvent être soumises à essai:
- connecteurs circulaires,
- connecteurs rectangulaires,
- connecteurs pour cartes de circuit imprimé,
- accessoires de blindage pour connecteur.
La présente méthode d’essai part du principe que la propriété intrinsèque du blindage de l’ensemble connecteur/accessoire/câble est son impédance de transfert de surface ZT, qui peut être exprimée par la tension longitudinale à l’intérieur du blindage, en fonction du courant parcourant le boîtier extérieur. Le présent essai est également adapté à la mesure de l’efficacité de blindage d’un connecteur équipé de contacts triaxiaux raccordés à des câbles blindés à paires torsadées, comme ceux utilisés dans les systèmes pour bus de données. Cette deuxième édition annule et remplace la première édition, parue en 2000. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) ajout d’une introduction visant à donner des recommandations dans le présent document relatives à la méthode d’essai parallèle 23g, figurant dans la même famille;
b) modification de la plage de fréquences pour laquelle la présente méthode d’essai est considérée fiable, dont la limite supérieure passe de 1 GHz à 3 GHz, afin d’assurer l’homogénéité avec la Figure 7 (inchangée) et les pratiques et besoins actuels de l’industrie;
c) mise à jour de l’ancienne référence normative IEC 60096-4-1:1990, retirée et incorrecte (la référence normative à spécifier aurait dû être l’IEC 61196-1:1995, depuis elle aussi retirée), qui devient l’IEC 62153-4-6:2017;
d) mise à jour des numéros de paragraphe actuels pour refléter ceux de l’IEC 62153 4 6:2017, qui étaient auparavant les numéros de paragraphe de l’IEC 61196 1:1995 (attribués par erreur à l’IEC 60096-4-1:1990). Dans un souci de clarification, le titre de ces paragraphes a été ajouté;
e) alignement du titre sur le domaine d’application actuel du SC 48B (connecteurs) et inclusion des équipements électriques comme application cible desdits connecteurs (selon le domaine d’application actuel du TC 48), et référence explicite à la méthode (ligne d’injection) utilisée pour la mesure de l’impédance de transfert;
f) ajout dans l’ensemble du document des symboles SE pour l’efficacité de blindage, et ZT pour l’impédance de transfert de surface;
g) déplacement dans le domaine d’application de la liste des connecteurs auxquels s’applique la méthode d’essai, auparavant indiquée en 3.1;
h) modification de l’ancien nom de l’organisation AECMA pour refléter son nom actuel, l’ASD-STAN;
i) utilisation du terme «éprouvette» à la place d’«échantillon» dans l’ensemble du document;
j) clarification dans le titre de l’impédance de trans

Konektorji za električno in elektronsko opremo - Preskusi in meritve - 23-3. del: Preskusi zaslanjanja in filtriranja - Preskus 23c: Oklepna učinkovitost konektorjev in pribora - Metoda injekcijskih linij (IEC 60512-23-3:2018)

Ta del standarda IEC 60512 določa standardno preskusno metodo za merjenje oklepne učinkovitosti zaslonjenega konektorja ali konektorja, ki po namestitvi oklepnega pribora in zaključku z zaslonjenim kablom nima vgrajenega oklepa.
Celoten sklop ima neprekinjeno 360-stopinjsko oklepno zmogljivost po vsej dolžini.
OPOMBA 1: V praksi neprekinjeni 360-stopinjski oklep ni vedno dosegljiv glede na geometrijo konektorja.
OPOMBA 2: »Oklopljen« se v tem dokumentu uporablja z enakim pomenom kot »zaslonjen«. Ta preskusna metoda se lahko uporablja pri oklopljenih konektorjih in priboru za konektorje z oklepno zmogljivostjo. Preskušati je mogoče naslednje različne modele konektorjev:
– okrogle konektorje;
– pravokotne konektorje;
– konektorje za plošče tiskanih vezij;
– pribor za oklopljanje konektorjev.
OPOMBA 3: Za opredelitev »pribora« glej standard IEV 581-24-10. Pribor za oklopljanje, tj. pribor, ki daje zaščito konektorju brez oklepa, je lahko ustrezen sestav oklopljenih ohišij, ki zagotavljajo neprekinjeno električno povezavo vzdolž sestava spojnega konektorja med zaslonom (zaslonjenega) kabla na kabelski spojki ohišja konektorja brez kabla in kovinski površini za pritrditev fiksnega ohišja konektorja. Gibljivo ohišje konektorja je na voljo z zaslonjeno kabelsko objemko.
Pri tej preskusni metodi se uporablja načelo, da je bistvena oklepna lastnost konektorja/pribora/kabelskega sklopa njegova površinska prehodna impedanca ZT, ki jo je mogoče izraziti kot vzdolžno napetost v oklopu glede na pretok električnega toka na zunanji lupini. Preskusna metoda temelji na dveh vezjih z ujemajočo se impedanco. Za načelo merjenja glej sliko 1. Primerek konektorja na preskusu je vgrajen v sekundarni tokokrog 02. Vpenjalna linija z ujemajočo se impedanco primarnega tokokroga 01, ki aktivira elektromagnetno polje, poteka vzporedno s površino preskušanega primerka.
Ta preskus je primeren tudi za merjenje oklepne učinkovitosti konektorja, pritrjenega s triaksialnimi kontakti, z zaključkom oklopljene parice, kot se uporablja v sistemih podatkovnih vodil.
OPOMBA 4: Ta standard je sprejela organizacija ASD-STAN (prej poznana kot AECMA) kot standard EN 2591-212.

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 60512-23-3 has been prepared by subcommittee 48B: Electrical
connectors, of IEC technical committee 48: Electrical connectors and mechanical structures
for electrical and electronic equipment.
This second edition cancels and replaces the first edition, published in 2000. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) an introduction has been added to provide some guidance to this document in view of
concurrent test method 23g in the same family;

---------------------- Page: 9 ----------------------

SIST EN IEC 60512-23-3:2019
– 4 – IEC 60512-23-3:2018 © IEC 2018
b) the frequency range for which this test method is considered reliable moved from 1 GHz
to 3 GHz, to be consistent with Figure 7 (unchanged) and current industry practice and
need;
c) update to IEC 62153-4-6:2017 of former normative reference IEC 60096-4-1:1990,
withdrawn and incorrect (should have been IEC 61196-1:1995, also withdrawn);
d) update to current subclause numbers of IEC 62153-4-6:2017 what were the previous
subclause numbers referenced in IEC 61196-1:1995 (wrongly attributed to IEC 60096-4-
1:1990). For immediate understanding the title of these subclauses has been added;
e) alignment of title to the current scope of SC 48B (connectors) and inclusion of electrical
equipment as target application of said connectors (per current scope of TC 48) and
explicit reference to the method – line injection – for the measurement of transfer
impedance;
f) symbols SE for shielding effectiveness and Z for surface transfer impedance added
T
throughout the document;
g) list of connectors to which the test method is applicable – previously in 3.1 – moved in
scope;
h) former name of AECMA organization changed to the current ASD-STAN;
i) “specimen” used instead of “sample” throughout the document;
j) clarification in the title of what transfer impedance is described in Table 3 and editorial
improvement of the same;
k) “dielectric constant” changed into the updated term “relative permittivity”;
l) added a note to warn about the fact that this test method requires in 6.6 a TDR with more
stringent rise time of less than 100 ps than the value of less than 350 ps specified both in
IEC 62153-4-6 and in EN 50289-1-6 for the similar line injection method applied to
screened cables, whereas test 23g of IEC 60512-23-7 specifies for the same purpose a
TDR with a rise time of less than 200 ps;
m) adoption of term “connector housing” [IEV 581-27-10] instead of “shell” to address the
connector accessory providing the shielding;
n) title “Transfer impedance Z [Ω]” added to the ordinate axis on the left side of double log
T
diagram of Figure 7;
o) explanatory note to clarify the conversion formula for SE from Z added.
