Environmental testing - Part 2-6: Tests - Test Fc: Vibration (sinusoidal)
Gives a method of test which provides a standard procedure to determine the ability of components, equipment and other articles, hereinafter referred to as specimens, to withstand specified severities of sinusoidal vibration. If an item is to be tested in an unpackaged form, that is without its packaging, it is referred to as a test specimen. However, if the item is packaged then the item itself is referred to as a product and the item and its packaging together are referred to as a test specimen. The purpose of this test is to determine any mechanical weakness and/or degradation in the specified performance of specimens and to use this information, in conjunction with the relevant specification, to decide upon the acceptability of the specimens. In some cases, the test method may also be used to demonstrate the mechanical robustness of specimens and/or to study their dynamic behaviour. Categorization of components can also be made on the basis of a selection from within the severities quoted in the test. The major changes with regard to the previous edition concern: - Reference to the latest version of IEC 60068-2-47:Mounting - Simplification of the layout of the standard by replacing some tables with text. - Addition of the test report requirements (see Clause 13).
Umgebungseinflüsse - Teil 2-6: Prüfverfahren - Prüfung Fc: Schwingen (sinusförmig)
Essais d'environnement - Partie 2-6: Essais - Essai Fc: Vibrations (sinusoïdales)
Fournit une méthode d'essai qui donne des règles d'exécution normalisées pour déterminer l'aptitude des composants, matériels et autres articles ci-après désignés 'spécimens', à résister à des sévérités spécifiées de vibrations sinusoïdales. S'il est prevu de soumettre un objet aux essais en étant non emballé, sans son emballage, il est désigné comme un spécimen d'essai. Cependant, si l'objet est emballé, alors l'objet lui-même est désigné comme produit et l'objet ainsi que son emballage sont désignés comme spécimen d'essai. L'objet de cet essai est de déterminer les faiblesses mécaniques et/ou les dégradations des performances spécifiées des spécimens, et d'utiliser ces renseignements conjointement avec la spécification particulière pour décider si un spécimen est acceptable ou non. Dans certains cas, la méthode d'essai peut également être utilisée pour démontrer la robustesse mécanique d'un spécimen et/ou pour étudier son comportement dynamique. La classification des composants en catégories peut également se faire sur la base d'une sélection faite à partir des sévérités données dans l'essai. Les modifications principales par rapport à l'édition précédente sont les suivantes: - Référence à la dernière version de la CEI 60068 2 47: Fixation. - Simplification de la mise en page de la norme en remplaçant quelques tableaux par du texte. - Ajout d'exigences sur le rapport d'essai (voir Article 13).

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 procedu
