Annotation of standard text IEC 60068-2-64-ed.2.1 :
IEC 60068-2-64:2008+A1:2019 demonstrates the adequacy of specimens to resist dynamic loads without unacceptable degradation of its functional and/or structural integrity when subjected to the specified random vibration test requirements. Broadband random vibration may be used to identify accumulated stress effects and the resulting mechanical weakness and degradation in the specified performance. This information, in conjunction with the relevant specification, may be used to assess the acceptability of specimens. This standard is applicable to specimens which may be subjected to vibration of a stochastic nature resulting from transportation or operational environments, for example in aircraft, space vehicles and land vehicles. It is primarily intended for unpackaged specimens, and for items in their transportation container when the latter may be considered as part of the specimen itself. 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. This standard may be used in conjunction with IEC 60068-2-47:2005, for testing packaged products. If the specimens are subjected to vibration of a combination of random and deterministic nature resulting from transportation or real life environments, for example in aircraft, space vehicles and for items in their transportation container, testing with pure random may not be sufficient. See IEC 60068-3-8:2003 for estimating the dynamic vibration environment of the specimen and based on that, selecting the appropriate test method. The major changes with regard to the previous edition concern the removal of Method 1 and Method 2, replaced by a single method, and replacement of Annex A with suggested test spectra and removal of Annex C. Also included in this revision is the testing of soft packed specimens.This consolidated version consists of the second edition (2008) and its amendment 1 (2019). Therefore, no need to order amendments in addition to this publication. LIEC 60068-2-64:2008+A1:2019 a pour objet de demontrer la capacite des specimens a resister aux charges dynamiques sans degradation inacceptable de leur integrite de fonctionnement et/ou de structure, lorsquils sont soumis a des exigences dessais de vibrations aleatoires specifiees. Lessai de vibration aleatoire a large bande peut etre utilise pour identifier les effets de contraintes accumulees ainsi que la faiblesse et la degradation mecaniques resultantes de la performance specifiee. Ces informations, conjointement avec la specification particuliere, peuvent etre utilisees pour evaluer lacceptabilite des specimens. Cette norme est applicable a des specimens qui peuvent etre soumis a des vibrations de nature stochastique dues au transport ou a lenvironnement rencontre en service, par exemple, a bord davions et de vehicules spatiaux ou a bord de vehicules terrestres. Elle est destinee en premier lieu a des specimens non emballes et a des objets dans leur emballage de transport lorsque celui-ci peut etre considere comme faisant partie du specimen lui-meme. Cependant, si larticle est emballe alors larticle lui-meme est designe comme produit et larticle ainsi que son emballage sont designes comme specimen dessai. Cette norme peut etre utilisee conjointement avec lIEC 60068-2-47:2005, pour lessai des produits emballes. Si les specimens sont soumis a des vibrations dune combinaison de nature aleatoire et deterministe resultant du transport ou des environnements de la vie reelle, par exemple a bord davions, de vehicules spatiaux et pour des elements dans leur emballage de transport, les essais purement aleatoires peuvent ne pas etre suffisants. Voir lIEC 60068-3-8:2003 pour lestimation de lenvironnement de vibrations dynamiques du specimen et sur cette base, pour la selection de la methode dessai appropriee. Les modifications principales par rapport a ledition precedente concernent le retrait de la Methode 1 et de la Methode 2, remplacees par une methode unique, et remplacement de lAnnexe A par des spectres dessais preconises et le retrait de lAnnexe C. Aussi inclus dans cette revision, lessai des specimens avec emballages mous.Cette version consolidee comprend la deuxieme edition (2008) et son amendement 1 (2019). Il nest donc pas necessaire de commander lamendement avec cette publication.
