General requirements, test methods and practical guidance
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 co-operation 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 express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are 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.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60352-1 has been prepared by subcommittee 48B: Connectors, of
IEC technical committee 48: Electromechanical components and mechanical structures for
electronic equipment.
This third edition cancels and replaces the second edition published in 1983, of which it
constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
48B/590/FDIS 48B/635/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
The contents of the corrigendum of October 1998 have been included in this copy.

INTRODUCTION
This part of IEC 60352 includes requirements, tests and practical guidance information.
Two test schedules are provided.
The basic test schedule applies to wrapped connections which conform to all the requirements
of clause 4.
These requirements are derived from experience with successful applications of such wrapped
connections.
The full test schedule applies to wrapped connections which do not fully conform to all the
requirements of clause 4, for example those which are manufactured using materials or
finishes not included in clause 4.
This approach permits cost- and time-effective performance verification using a limited basic
test schedule for established wrapped connections and an expanded full test schedule for
wrapped connections requiring more extensive performance validation.

SOLDERLESS CONNECTIONS –
Part 1: Wrapped connections –
General requirements, test methods and practical guidance
1 Scope and object
This part of IEC 60352 is applicable to wrapped connections made with single solid round wires
with nominal diameters of 0,16 mm minimum and appropriately designed posts for use in
telecommunications equipment and in electronic devices employing similar techniques.
Information on materials and data from industrial experience are included in addition to the test
procedures to provide electrically stable connections under prescribed environmental conditions.
The object of this standard is to determine the suitability of wrapped connections under
specified mechanical, electrical and atmospheric conditions, and to provide a means of
comparing test results when the tools used to make the connections are of different design or
manufacture.
2 Normative references

3 Definitions
For the purpose of this part of IEC 60352, the terms and definitions included in IEC 60050(581)
and IEC 60512-1 and the following additional terms and definitions apply.

3.3 conventional wrapped connection: A solderless connection achieved by wrapping a
solid conductor around a wrap post without any contact of the wire insulation to the post (see
figure 2a). [IEV 581-03-45]
3.4 modified wrapped connection: A solderless connection achieved by wrapping a solid
conductor around a wrap post with the wire insulation wrapped around at least three corners of
