FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
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. The 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 the IEC on technical matters, prepared by technical committees on
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.
3) They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
International Standard IEC 352-4 has been prepared by IEC sub-committee 48B: Con-
nectors, of IEC technical committee 48: Electromechanical components and mechanical
structures for electronic equipment.
The text of this standard is based on the following documents:

48B(CO)251 48B(CO)256
Full information on the voting for the approval of this standard can be found in the report
on voting indicated in the above table.

INTRODUCTION
The two following parts of IEC 352 are available on solderless insulation displacement
connections:
Part 3: Solderless accessible insulation displacement connections – General
–
requirements, test methods and practical guidance;
Part 4: Solderless non-accessible insulation displacement connections – General
–
requirements, test methods and practical guidance.
These parts include requirements, tests and practical guidance information.
Two test schedules are provided:
basic test schedule which applies to insulation displacement connections which
– the
of section 2 of this standard;
conform to all requirements
These requirements are derived from experience with successful applications of such
connections.
full which applies to insulation displacement connections which do
– the test schedule
section 2, for example which are manufactured
not fully conform to all requirements of
using materials or finishes not included in section 2.
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.
NOTE — In this standard the term "insulation displacement" is abbreviated to "ID", for example "ID connec-
tion", 'ID termination".

Section 1: General
1 Scope
This part of IEC 352 is applicable to non-accessible ID connections for which the tests and
measurements of section 3 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;
—
2 to 10 mm 2 cross-section;
— wires having stranded conductors of 0,05 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
The object of this part of IEC 352 is to:
determine the suitability of non-accessible ID connections under specified mech-
—
anical, electrical and atmospheric conditions;
— provide a means of comparing test results when the tools used to make the
connections are of different designs or manufacture.
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 require-
ments of the wire and the complete connection are specified in full detail.
3 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this part of IEC 352. At the time of publication, the editions
rties to
indicated were valid. All normative documents are subject to revision, and pa
agreements based on this part of IEC 352 are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below.
