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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 60512-8-3 has been prepared by subcommittee 48B: Electrical
connectors, of IEC technical committee 48: Electrical connectors and mechanical structures
for electrical and electronic equipment.
This second edition cancels and replaces the first edition published in 2011. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) This edition reflects IEC 60512-1-101, Blank detail specification.
b) Subclause 4.2 (Preparation of specimen) is improved.

TESTS AND MEASUREMENTS –
Part 8-3: Static load tests (fixed connectors) –
Test 8c: Robustness of actuating lever

1 Scope
This part of IEC 60512, when required by the detail (product) specification, is used for testing
connectors within the scope of IEC technical committee 48. It may also be used for similar
devices, when specified in a detail (product) specification.
The object of this document is to detail a standard test method to assess the robustness of
the actuating lever of a connector mating or release mechanism.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements 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.

Part 1: General
IEC 60512-1-1, Connectors for electrical and electronic equipment – Tests and measurements
– Part 1-1: General Examination – Test 1a: Visual examination
3 Terms and definitions
For the purposes of this document, the terms and definitions from IEC 60512-1 apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
4 Preparations
4.1 Test equipment
A suitable test device and appropriate fixture shall be used.
4.2 Preparation of specimen
A specimen of connector or similar device shall be equipped with a mating/release
mechanism (latching/unlatching) including an actuating lever.
The number of specimens to prepare shall be as specified in the detail (product) specification

– 6 – IEC 60512-8-3:2018 © IEC 2018
4.3 Mounting of specimen
Mounting of the specimen shall be as specified in the detail (product) specification.
Unless otherwise specified, the specimen shall be mounted in the normal manner, using the
normal panel or chassis cut-out as laid down in the detail (product) specification.
The panel or chassis should be strong enough to sustain the applied forces. The length and
width of the panel or chassis should be longer and wider enough than the contour of the
specimen.
5 Test / measuring method
5.1 Pre-conditioning
Specimens shall be subject to the preconditioning as specified in the detail (product)
specification.
5.2 Initial measurements
Visual examination according to IEC 60512-1-1 shall be done.

in the detail product specification.
a) Test method A: Force
Force specified in the detail (product) specification shall be applied at the tip of the actuating
lever. This force shall be applied in each of the following directions (see Figure 1):
