SOLDERLESS CONNECTIONS
Part 3: Solderless accessible insulation displacement connections —
General requirements, test methods and practical guidance
FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
1)
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
They have the form of recommendations for international use and they are accepted by the National
2)
Committees in that sense.
In order to promote international unification, the IEC expresses the wish that all National Committees
3)
should adopt the text of the IEC recommendation for their national rules in so far as national conditions will
permit. Any divergence between the IEC recommendation and the corresponding national rules should, as
far as possible, be clearly indicated in the latter.
The IEC has not laid down any procedure concerning marking as an indication of approval and has no
4)
responsibility when an item of equipment is declared to comply with one of its recommendations.
International Standard IEC 352-3 has been prepared by IEC technical committee 48:
Electromechanical components and mechanical structures for electronic equipment.
The text of this standard is based on the following documents:
DIS Report on Voting
48(CO)339
48(CO)331
Full information on the voting for the approval of this standard can be found in the Voting
Report indicated in the above table.

INTRODUCTION
Two standards are available on solderless insulation displacement connections:
Part 3: Solderless accessible insulation displacement connections – General require-
ments, test methods and practical guidance;
Part 4: Solderless non-accessible insulation displacement connections – General
requirements, test methods and practical guidance.
This standard includes requirements, tests and practical guidance information.
Two test schedules are provided:
The Basic Test Schedule applies to insulation displacement connections which
–
conform to all requirements of section 2.
These requirements are derived from experience with successful applications of such
connections.
– The Full Test Schedule applies to insulation displacement connections which do not
fully conform to all requirements of section 2, for example those which are manu-
factured using materials or surface finishes not included in section 2.
This philosophy permits cost and time effective performance verification using a limited
Basic Test Schedule for established connections and an expanded Full Test Schedule
for connections requiring more extensive performance validation.
NOTE - In this standard the term Insulation displacement" is abbreviated to "ID", for example "ID connec-
tion" , "ID termination".

SOLDERLESS CONNECTIONS
Part 3: Solderless accessible insulation displacement connections –
General requirements, test methods and practical guidance
SECTION 1: GENERAL
1 Scope
This part of IEC 352 is applicable to ID connections which are accessible for tests and
measurements according to section 3 and which are made with:
appropriately designed ID terminations;
— wires having solid round conductors of 0,25 mm to 3,6 mm nominal diameter;
— 2 cross-section;
wires having stranded conductors of 0,05 mm 2 to 10 mm
for use in telecommunication equipment and in electronic devices employing similar
techniques.
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.
2 Object
To determine the suitability of accessible ID connections under specified mechanical,
electrical and atmospheric conditions.
There are different designs and materials for ID terminations in use. For this reason only
rformance require-
fundamental parameters of the termination are specified while the pe
ments of the wire and the complete connection are specified in full detail.
To provide a means of comparing test results when the tools used to make the connec-
tions are of different designs or manufacture.

4 Definitions
Terms and definitions used in and applicable to this part of IEC 352 are included in
IEC 50(581). IEC 512-1 also contains some applicable terms and definitions.
352-3 © IEC: 1993 - 13 -
For the purpose of this part of IEC 352, the following additional terms and definitions
shall apply.
4.1
Insulation displacement connection (ID connection)
A solderless electrical connection made by inserting a single wire into a precisely
controlled slot in a termination such that the sides of the slot displace the insulation and
deform the conductor of a solid wire or strands of stranded wire to produce a gas-tight
connection.

stranded conductors

4.1.1
Accessible insulation displacement connection (accessible ID connection)
An ID connection in which it is possible to access test points for carrying out mechanical
tests (for example, transverse extraction force) and electrical measurements (for example,
contact resistance) without deactivation of any design feature intended to establish and/or
maintain the ID connection.
4.1.2
Non-accessible insulation displacement connection (non-accessible ID connection)
(See IEC 352-4, under consideration)
An ID connection in which it is not possible to access test points for carrying out mecha-
nical tests such as transverse extraction force and some electrical measurements (for ex-
ample, contact resistance) without deactivation of any design feature intended to establish
and/or maintain the ID connection, mainly where the ID connection is enclosed in a compo-
nent.
