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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60512-16-17 has been prepared by subcommittee 48B,
Connectors, of IEC technical committee 48: Electromechanical components and mechanical
structures for electronic equipment.
This standard cancels and replaces Test 16q of IEC 60512-8, issued in 1993. This standard is
to be read in conjunction with IEC 60512-1 and IEC 60512-1-100 which explains the structure
of the IEC 60512 series.
The text of this standard is based on the following documents:
FDIS Report on voting
48B/1891/FDIS 48B/1924/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.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of the IEC 60512 series, under the general title Connectors for electronic
equipment – Tests and measurements, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

Part 16-17: Mechanical tests on contacts and terminations –
Test 16q: Tensile and compressive strength, fixed male tabs

1 Scope and object
This part of IEC 60512, when required by the detail specification, is used for testing
electomechanical components within the scope of technical committee 48. It may also be
used for similar devices when specified in a detail specification.
The object of this part of IEC 60512 is to detail a standard test method to determine the ability
of a fixed male tab and its fixing to withstand specified tensile and compressive forces. If so
specified in the detail specification, forces other than tension and compression may be
applied.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 60512-1-1, Connectors for electronic equipment – Tests and measurements – Part 1-1:
General examination – Test 1a: Visual examination
3 Preparations
3.1 Preparation of specimen
The specimens shall consist of a connector fitted with one or more male tabs. They may be
wired if so specified in the detail specification. Any preconditioning given in the detail
specification shall be applied. Three such specimens shall be provided.
3.2 Equipment
For the application of the axial loads, a suitable device able to provide the controls on the
loads (intensity, rate of increase, time of constant load application) shall be required (e.g.: a
universal materials testing machine).
NOTE If the detail specification requires special preconditioning of the specimen, all the necessary equipment
detailed in the relevant documents describing such conditioning would also be required.
An illustration of the application of force is given in Figure 1.
3.3 Mounting
If mounting of the specimen is appropriate, it shall be as specified in the component detail
specification.

4 Test method
4.1 General
At least 10 tabs shall be selected at random from the 3 specimens of which at least one tab
shall be near the periphery, and one, at or near the centre of the connector insert or housing.
For inserts or housings having 3 or less tabs, all tabs shall be tested. This shall be repeated,
on an adjacent (new) tab, with the force being applied in the opposite direction (i.e. if tensile
is first applied then compression is the next test).
A tensile or compressive force F shall be applied to the fixed tab. The tensile or compressive
force shall be steadily increased from zero to that specified in the component specification.
This tensile or compressive force shall be maintained for 1 minute.
The tensile or compressive force shall then be removed, and the (permanent) displacement of
the tab shall be measured after the removal of the tensile or compressive force. Permanent
displacement is defined as the difference between the initial position of the tab before
application of any tensile or compressive forces and its position after all tensile and
compressive force is removed.
4.2 Measurements and requirements
4.2.1 Before testing
Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no
defects, which would impair the validity of the test.
4.2.2 During testing
The displacement and permanent displacement of the component, measured at the plane of
application of the tensile and compressive forces shall be measured.
