Environmental testing - Part 2-31: Tests - Test Ec: Rough handling shocks, primarily for equipment-type specimens

IEC 60068-2-31:2008 deals with a test procedure for simulating the effects of rough handling shocks, primarily in equipment-type specimens, the effects of knocks, jolts and falls which may be received during repair work or rough handling in operational use. This procedure does not simulate the effects of impacts received during transportation as loosely constrained cargo. Where the effects of loose cargo transportation are to be assessed, test Ee: Bounce should be used. Also this procedure does not simulate the effects of shock applied to installed equipments. Where this effect is to be assessed refer to test Ea: Shock. Testing should only be specified for equipment likely to receive such rough handling, for example those of small to medium size and mass, and should only be applied to those faces and corners where there is a risk of such treatment being encountered. In general, equipment which is frequently handled and serviced (for example field equipment and unit spares) can be considered at risk, whereas equipment forming an integral part of a permanent installation would not normally be considered at risk and need not be tested. Testing may not be applicable to fragile unprotected equipment of irregular shape (for example aircraft nose radar) which, when removed from the installation would be contained in a handling frame or jig. It may however be applicable to these items of equipment when they are in their transit case or in their handling frame or jig. For equipment which stands only on one face (for example the normal base) the test is generally only applied to that face. Shock tests are performed on the specimen when fixed to the test machine. Drop and topple, free fall, repeated free fall and bounce tests are performed with the specimen free. This second edition cancels and replaces the first edition, published in 1969 and constitutes a technical revision. The major changes with regard to the previous edition concern the introduction of soft packaging tests, where appropriate. This new edition of IEC 60068-2-31 now incorporates the second edition of IEC 60068-2-32 (1975). Has the status of a basic safety publication in accordance with IEC Guide 104.

Essais d'environnement - Partie 2-31: Essais -Essai Ec: Choc lié à des manutentions brutales, essai destiné en premier lieu aux matériels

La CEI 60068-2-31:2008 consiste en une procédure d'essai pour la simulation des effets de chocs lié à des manutentions brutales, principalement pour les spécimens tels que des matériels, les effets des coups, des heurts et des chutes qui peuvent être reçus au cours de réparations ou de manutentions brutales durant leur fonctionnement. Cette méthode ne simule pas les effets d'impacts reçus pendant le transport sans arrimage. Lorsqu'il est prévu d'évaluer les effets du transport sans arrimage il convient d'utiliser l'essai Ee: de rebondissement. Cette méthode ne simule donc pas les effets de chocs appliqués aux équipements installés. Lorsque il est prevu d'évaluer cet effet, se référer à l'essai Ea de chocs. Il convient que cet essai ne soit normalement spécifié que pour les matériels susceptibles d'être ainsi manipulés, par exemple ceux dont la taille et la masse sont moyennes ou petites, et n'être appliqué qu'aux faces ou coins qui risquent de subir un tel traitement. En général, on peut considérer qu'un matériel qui est fréquemment manipulé et entretenu (par exemple, les matériels de servitude et les unités de rechange) court un tel risque, alors que l'on considérera qu'un matériel qui fait partie intégrante d'une installation fixe ne court normalement pas ce risque et n'a pas besoin d'être soumis à cet essai. Cet essai peut ne pas être applicable aux matériels fragiles et non protégés dont la forme est irrégulière (par exemple un radar frontal d'avion) qui, lorsqu'ils sont retirés de l'installation fixe, sont généralement placés dans un berceau ou un cadre de manutention. Il peut toutefois être applicable à ces matériels lorsqu'ils sont dans leur emballage de transport, ou dans leur berceau ou cadre de manutention. Pour les matériels qui ne tiennent dressés que sur une face (par exemple la base normale), on n'exécute généralement l'essai que sur cette seule face. On exécute les essais de chocs en fixant le spécimen à la machine d'essai. Les essais de chute et culbute, de chute libre, de chutes libres répétées et de rebondissement sont exécutés sur des spécimens non fixés. Cette deuxième édition annule et remplace la première édition, publiée en 1969, et constitue une révision technique. Les modifications principales par rapport à l'édition précédente concernent l'introduction, aux endroits appropriés, des essais sur les emballages. Par ailleurs, la deuxième édition de la CEI 60068-2-32 (1975) a été incorporée dans cette nouvelle édition de la CEI 60068-2-31. A le statut d'une publication fondamentale de sécurité conformément au Guide 104 de la CEI

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 60068-2-31 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 1969 and constitutes a
technical revision.
The major changes with regard to the previous edition concern the introduction of soft
packaging tests, where appropriate. This new edition of IEC 60068-2-31 now incorporates the
second edition of IEC 60068-2-32 (1975).
IEC 60068-2-32 will be withdrawn once this standard has been issued.
