Solderless connections - Part 4: Non-accessible insulation displacement (ID) connections - General requirements, test methods and practical guidance (IEC 60352-4:2020)
IEC 60352-4:2020 is applicable to non-accessible ID connections for which the tests and measurements according to Clauses 6 through 8 are suitable and which are made with:
– appropriately designed ID terminations;
– wires having solid round conductors of 0,25 mm to 3,6 mm nominal diameter;
– wires having stranded conductors of 0,05 mm2 to 10 mm2 cross-sectional area;
for use in electrical and electronic equipment and components.
Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions.
There are different designs and materials for ID terminations in use. For this reason, only fundamental parameters of the termination are specified, while the performance requirements of the wire and the complete connection are specified in full detail.
The purpose of this document is:
– to determine the suitability of non-accessible ID connections under specified mechanical, electrical and atmospheric conditions;
– to provide a means of comparing test results when the tools used to make the connections, if any, are of different designs or manufacture.
This second edition cancels and replaces the first edition, published in 1994, and its Amendment 1 (2000). This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Transferred Clauses 9 to 13 into Annex A (informative).
b) The figures were re-drawn for clarity.

IEC 600352-4:2020 s'applique aux connexions CAD non accessibles pour lesquelles les essais et les mesures conformes aux Articles 6 à 8 sont appropriés et qui sont composées de:
– contacts CAD de conception appropriée;
– fils à conducteurs cylindriques massifs de diamètre nominal 0,25 mm à 3,6 mm;
– fils à conducteurs divisés de section 0,05 mm2 à 10 mm2;
pour l'utilisation dans les équipements et composants électriques et électroniques.
Des informations sur les matières et des résultats dus à l'expérience industrielle y sont inclus en plus des méthodes d'essai pour assurer des connexions électriquement stables dans les conditions d'environnement prescrites.
Il y a différentes conceptions et matières utilisées pour les contacts CAD. C'est pourquoi seuls les paramètres fondamentaux du contact sont spécifiés, tandis que les exigences des performances du fil et de la connexion terminée sont définies dans tous les détails.
Le présent document a pour objet de:
– déterminer la conformité des connexions CAD non accessibles dans des conditions mécaniques, électriques et atmosphériques spécifiées;
– fournir un moyen de comparaison des résultats d'essai quand les outils utilisés pour faire les connexions, le cas échéant, sont de conceptions ou de fabrications différentes.
Cette deuxième édition annule et remplace la première édition parue en 1994, et son Amendement 1 (2000). La présente édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les Articles 9 à 13 ont été transférés à l'Annexe A (informative);
b) les figures ont été retravaillées pour plus de clarté.

SOLDERLESS CONNECTIONS –
Part 4: Non-accessible insulation displacement (ID) connections –
General requirements, test methods and practical guidance
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 60352-4 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 1994, and its
Amendment 1 (2000). This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Transferred Clauses 9 to 13 into Annex A (informative).
b) The figures were re-drawn for clarity.
