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 60512-7-2 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 7b of IEC 60512-5, issued in 1992. The structure of
the test documents in the IEC 60512 series is explained in IEC 60512-1-100.
The text of this standard is based on the following documents:

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 standard is to detail a standard test method to assess the ability of a free
connector on the end of a cable or wire bundle to withstand impacts it could receive when
dropped onto a hard surface.
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 Preparation
3.1 Preparation of the specimen
The specimen shall consist of a free connector or a similar component with its accessories
fitted in the normal manner and wired as used in the normal application.
The specimen shall be prepared in accordance with the detail specification.
Unless otherwise specified, the specimen shall be pre-conditioned at a temperature between
15 °C and 35 °C and a RH between 25 % and 75 % RH during 48 h.
If the component is normally provided for use with different types of cables, the thinnest
and/or most flexible type shall be used. The length of the cable or wire bundle shall allow the
rear of the specimen to be (2 250 ± 10) mm from the point of attachment.
3.2 Equipment
A steel plate 300 mm × 500 mm of 25 mm thickness shall be positioned so that the component
under test will fall onto it.
3.3 Mounting
The specimen shall be attached in an appropriate manner at a distance of (2 250 ± 10) mm
from the rear of the component so that the specimen may swing freely from a horizontal to a
vertical position as shown in Figure 1.

– 6 – 60512-7-2  IEC:2011
NOTE An appropriate manner may be the attachment to a swivel. In many cases, however, simply attaching to a
hook may be sufficient.
The specimen shall be attached at one of the following preferred heights:
(2 000 ± 10) mm
(1 750 ± 10) mm
(1 500 ± 10) mm
(1 250 ± 10) mm
