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 60512-16-8 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 16h 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.

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

Part 16-8: Mechanical tests on connections and terminations –
Test 16h: Insulating grip effectiveness (crimped connections)

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 part of IEC 60512 is to detail a standard test method to assess the
effectiveness of an insulation grip to hold the insulation of a cable/wire under specified
conditions.
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 even quantities of cable with the largest insulation specified
for the grip, and the smallest.
The specimens shall consist of a crimp contact or terminal end and the specified cable(s);
these shall be prepared (crimped) in the manner given in the relevant detail specification or if
none are given, the manufacturers instructions. The crimp contact/terminal end shall be
crimped in the manner previously stated, but the cable/wire shall be held by the insulation grip
only.
NOTE Either crimping a separate piece of wire or cutting the conductor after crimping may achieve this.
The un-stripped cable/wire shall be at least 100 mm in length. If lubricant is required by the
component detail specification, this shall be applied in the manner so specified. Similarly, if
the manufacturers crimping or other assembly devices specify a lubricant, this shall be
applied.
3.2 Equipment
A mandrel having a diameter equal to that as specified for the flexibility test of the relevant
wire/cable shall be provided.
60512-16-8 © IEC:2008 – 5 –
3.3 Pre-conditioning
Any pre-conditioning of the samples required by the applicable detail specification shall be
applied.
4 Test method
4.1 Temperature
It is recognized that temperature has a significant effect on the flexibility of cable insulation.
These tests shall be carried out under normal laboratory conditions unless otherwise stated in
the relevant detail specification.
4.2 Procedure
The crimp(ed) contact/terminal shall be held tangential to the mandrel. The wire shall be
wound around the mandrel for at least one complete turn and shall be in contact with the
mandrel where it enters the insulation grip. Sufficient tension, as specified in the relevant
detail specification, shall be applied to the wire to keep it in contact with the mandrel. A test
made by first winding the wire in one direction then in the opposite direction shall be
considered one cycle. This cycle shall be done at least ten times.
The rotational position of the specimen relative to the direction of bending shall be varied
during each cycle such that forces are applied in at least four directions mutually at right
angles to each other relative to the grip.
NOTE It is recognized that grip devices have a ‘best’ and ‘worst’ direction of support. The above requirement is
intended to test in both the ‘best’ and ‘worst’ directions.
4.3 Measurements and requirements
4.3.1 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.
4.3.2 During testing
None.
4.3.3 After testing
The conductor shall be withdrawn from the cable/wire and examined for damage (caused by
either the grip crimping process or the testing). This may be done by stripping the insulation
from the far end of the cable/wire and applying a tensile load between the bared conductor
and the crimp terminal.
Visual examination according to IEC 60512-1-1 shall be done. There shall be no defects,
other than those found under 4.3.1, which would impair the normal functioning of the
component.
5 Details to be specified
When this test is required by the detail specification, the following
