Solderless connections - Part 3: Accessible insulation displacement (ID) connections - General requirements, test methods and practical guidance (IEC 60352-3:2020)

This part of IEC 60352 is applicable to ID connections which are accessible for tests and
measurements according to Clauses 6 through 8 and which are made with:
– appropriately designed accessible 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 accessible 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 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.

Connexions sans soudure - Partie 3: Connexions autodénudantes accessibles sans soudure - Règles générales, méthodes d'essai et guide pratique (IEC 60352-3:2020)

IEC 60352-3:2020 est applicable aux connexions CAD qui sont accessibles pour les essais et les mesures conformes aux Articles 6 à 8 et qui sont composées de: – contacts CAD accessibles 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 accessibles. 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 accessibles dans des conditions méca-niques, 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 diffé-rentes. Cette deuxième édition annule et remplace la première édition parue en 1993. Cette édi-tion constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édi-tion précédente: a) Paragraphe 7.2.2: il réduit la limite de la durée de la perturbation de contact à 1 µs. b) Paragraphe 7.2.3: il réduit la limite de la durée de la perturbation de contact à 1 µs. c) Les Articles 9 à 13 ont été transférés à l’Annexe A (informative). d) Les figures ont été révisées pour plus de clarté.

Part 3: 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 interna-

tional 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, Tech-

nical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publica-

tion(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 Interna-

tional 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 inter-

ested 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 misinter-

pretation 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 be-

tween 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 ex-

penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-

tions.

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 60352-3 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 1993. This edition con-

stitutes a technical revision.

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

edition:
a) Subclause 7.2.2: reduce the limit of duration of contact disturbance to 1 µs.
b) Subclause 7.2.3: reduce the limit of duration of contact disturbance to 1 µs.
c) Transferred Clauses 9 to 13 to Annex A (informative).
d) The figures were revised for clarity.

INTRODUCTION

The two following parts of IEC 60352 are available on solderless insulation displacement con-

nections:

– Part 3: Accessible insulation displacement connections – General requirements, test

methods and practical guidance;

– Part 4: Solderless non-accessible insulation displacement connections – General require-

ments, test methods and practical guidance.

NOTE In this document the term "insulation displacement" is abbreviated to "ID", for example "ID connection", "ID

termination".

Figure 1 illustrates examples of accessible and non-accessible insulation displacement con-

nections that clarify the difference among them.

Part 3 includes requirements and relevant tests (normative) as well as a practical guidance in

Annex A (informative) for accessible ID connections.
Two test schedules are provided:

– the basic test schedule which applies to insulation displacement connections which con-

form to all prerequisites of Clause 5. It is derived from experience with successful applica-

tions of such connections;

– the full test schedule which applies to insulation displacement connections which do not

fully conform to all prerequisites of Clause 5, for example which are manufactured using

materials or finishes not included in Clause 5.

This philosophy permits cost and time effective performance verification using a limited basic

test schedule for established insulation displacement connections and an expanded full test

schedule for connections requiring more extensive performance validation.
