Environmental testing - Part 2-55: Tests - Test Ee and guidance - Loose cargo testing including bounce
IEC 60068-2-55:2013 provides a standard procedure for determining the ability of a specimen to withstand specified severities of bounce, e. g. when transported as loose cargo on wheeled vehicles. This second edition cancels and replaces the first edition, published in 1987, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: This new edition allows for loose cargo testing in a more general sense. The test is no longer aligned with a special testing machine but allows for use of any suitable equipment such as electrodynamic or servo-hydraulic shaker tables. Moreover, sinusoidal and random vibration can be used. The previous rotation table motions are included in Annex A as historical methods.
This publication is to be read in conjunction with IEC 60068-1:1988.
Essais d'environnement - Partie 2-55: Essais - Essai Ee et guide - Essais de chargement sans arrimage y compris l'essai de rebondissement
La CEI 60068-2-55:2013 fournit une procédure normalisée permettant de déterminer l'aptitude d'un spécimen à résister à des sévérités spécifiées de rebondissement, lorsqu'il est transporté par exemple sans arrimage sur des véhicules à roues. Cette deuxième édition annule et remplace la première édition, publiée en 1987. Elle constitue une révision technique. Les modifications principales par rapport à l'édition précédente sont les suivantes: Cette nouvelle édition prévoit des essais de chargement sans arrimage dans un sens plus général. L'essai n'est plus conduit à l'aide d'un appareil spécial d'essai mais permet d'utiliser tout matériel approprié tel que les tables vibrantes électrodynamiques ou servo-hydrauliques. De plus, les vibrations sinusoïdales et aléatoires peuvent être utilisées. Les mouvements antérieurs de la table de rotation sont inclus dans l'Annexe A à titre de méthodes historiques.
Cette publication doit être lue conjointement avec la CEI 60068-1:1988.

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 60068-2-55 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This second edition cancels and replaces the first edition, published in 1987, and constitutes
a technical revision.
The main changes with respect to the previous edition are listed below:
This new edition allows for loose cargo testing in a more general sense. The test is no longer
aligned with a special testing machine but allows for use of any suitable equipment such as
electrodynamic or servo-hydraulic shaker tables. Moreover, sinusoidal and random vibration
can be used. The previous rotation table motions are included in Annex A as historical
methods.
