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 60512-15-2 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 15b 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.
60512-15-2 © IEC:2008 – 3 –
The text of this standard is based on the following documents:

FDIS Report on voting
48B/1844/FDIS 48B/1896/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.

CONNECTORS FOR ELECTRONIC EQUIPMENT –

TESTS AND MEASUREMENTS –
Part 15-2: Connector tests (mechanical) –

Test 15b: Insert retention in housing (axial)

1 Scope and object
This part of IEC 60512, when required by the detail specification, is used for testing
connectors 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 document is to detail a standard test method to assess the effectiveness of
the insert retaining system to withstand axial loads likely to be encountered during normal
use.
NOTE The test method detailed in this document is a companion to the one detailed in IEC 60512-15-3 (see
bibliographic reference).
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 specimen shall consist of a connector with its terminations, and may be wired if so
specified in the detail specification. Cable fittings and accessories shall not be fitted. Any
preconditioning given in the detail specification shall be applied.

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).
In the case of the axial loads being applied by air or gas pressure, a chamber to contain
connectors that may be ejected in case of retention failure shall be provided. If hydraulic
pressure is used, such a chamber may not be necessary. However compatibility between
materials contained within the specimen and such fluids must be ensured.
NOTE 1 Where air pressure is used, there is a possibility that contacts, inserts or other objects being ejected at
high velocity.
NOTE 2 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.

60512-15-2 © IEC:2008 – 5 –
3.3 Mounting
Mounting of the specimen shall be as specified in the detail specification.

4 Test method
4.1 Procedure
Unless otherwise stated in the detail specification, 3 connectors shall be tested.

4.1.1 Force method
The housing of the connector shall be fixed in such a manner as not to influence the insert
retention means.
A specified axial force shall be applied in both directions consecutively, at a constant rate of
25 mm/min, until the specified force is achieved. This shall then be maintained for 1 minute.
4.1.2 Pressure method
The displacement caused by the specified force or pressure – if any – shall be measured. Any
residual displacement after the specified force or pressure is removed – if any – shall be
measured. These displacements shall be recorded.
The axial displacement of the insert shall not exceed that which may be given in the detail
specification.
4.2 Measurements
4.2.1 Before testing
Visual examination according to IEC 60512-1-1 shall be done.
4.2.2 During testing
There shall be no displacement of the insert during or after the test that would impair the
normal operation of the connector.
4.2.3 After testing
Visual examination according to IEC 60512-1-1 shall be done.

5 Details to be specified
When this test is required by a detail specification, the following shall be given therein:
a) the number of connectors to test if other than 3;
b) preconditioning required;
c) wiring of the specimen;
d) mounting of the specimen;
e) axial load or pressure to be applied;
f) permitted displacement, if any (during and after the test);
g) any deviation from the standard test method.
