Environmental testing - Part 2-64: Tests - Test Fh: Vibration, broadband random and guidance

IEC 60068-2-64:2008 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. Has the status of a basic safety publication in accordance with IEC Guide 104.

Essais d'environnement - Partie 2-64: Essais - Essai Fh: Vibrations aléatoires à large bande et guide

La CEI 60068-2-64:2008 a pour objet de démontrer la capacité des spécimens à résister aux charges dynamiques sans dégradation inacceptable de leur intégrité de fonctionnement et/ou de structure, lorsqu'ils sont soumis à des exigences d'essais de vibrations aléatoires spécifiées. L'essai de vibration aléatoire à large bande peut être utilisé pour identifier les effets de contraintes accumulées ainsi que la faiblesse et la dégradation mécaniques résultantes de la performance spécifiée. Ces informations, conjointement avec la spécification particulière, peuvent être utilisées pour évaluer l'acceptabilité des spécimens. Cette norme est applicable à des spécimens qui peuvent être soumis à des vibrations de nature stochastique dues au transport ou à l'environnement rencontré en service, par exemple, à bord d'avions et de véhicules spatiaux ou à bord de véhicules terrestres. Elle est destinée en premier lieu à des spécimens non emballés et à des objets dans leur emballage de transport lorsque celui-ci peut être considéré comme faisant partie du spécimen lui-même. Cependant, si l'article est emballé alors l'article lui-même est désigné comme produit et l'article ainsi que son emballage sont désignés comme spécimen d'essai. Cette norme peut être utilisée conjointement avec la CEI 60068 2 47:2005, pour l'essai des produits emballés. Si les spécimens sont soumis à des vibrations d'une combinaison de nature aléatoire et déterministe résultant du transport ou des environnements de la vie réelle, par exemple à bord d'avions, de véhicules spatiaux et pour des éléments dans leur emballage de transport, les essais purement aléatoires peuvent ne pas être suffisants. Voir la CEI 60068-3-8:2003 pour l'estimation de l'environnement de vibrations dynamiques du spécimen et sur cette base, pour la sélection de la méthode d'essai appropriée. Les modifications principales par rapport à l'édition précédente concernent le retrait de la Méthode 1 et de la Méthode 2, remplacées par une méthode unique, et remplacement de l'Annexe A par des spectres d'essais préconisés et le retrait de l'Annexe C. Aussi inclus dans cette révision, l'essai des spécimens avec emballages mous. A le statut de publication fondamentale de sécurité, conformément au Guide CEI 104.

Okoljski preskusi - 2-64. del: Preskusi - Preskus Fh: Vibracije, naključne širokopasovne, in vodilo (IEC 60068-2-64:2008)

Ta del standarda IEC 60068 izkazuje primernost primerkov glede odpornosti proti dinamičnim obremenitvam brez nesprejemljivega poslabšanja funkcionalne in/ali strukturne celovitosti, kadar so izpostavljeni podanim naključnim zahtevam preskušanja vibracij. Naključne širokopasovne vibracije se lahko uporabijo za določanje nakopičenih učinkov obremenitve ter posledične mehanske šibkosti in poslabšanja podanih lastnosti. Te informacije se lahko skupaj z ustrezno specifikacijo uporabijo za vrednotenje sprejemljivosti primerkov. Ta standard se uporablja za primerke, ki so lahko izpostavljeni stohastičnim vibracijam zaradi transportnih ali obratovalnih okolij, na primer v letalih, vesoljskih plovilih in kopenskih vozilih. Prvotno je namenjen nezapakiranim primerkom in predmetom v njihovem transportnem vsebniku, pri čemer se slednji lahko obravnava kot del samega primerka. Kadar pa je predmet zapakiran, se sam predmet obravnava kot izdelek, izdelek in njegova embalaža pa se obravnavata kot preskušanec. Ta standard se lahko uporablja v povezavi s standardom IEC 60068-2-47:2005 za preskušanje zapakiranih izdelkov. Če so primerki izpostavljeni kombinaciji naključnih in določenih vibracij zaradi transportnih ali dejanskih življenjskih okolij (na primer v letalih, vesoljskih plovilih in za predmete v njihovem transportnem vsebniku), preskušanje zgolj z naključnimi morda ne bo zadostovalo. Glej standard IEC 60068-3-8:2003 za ocenjevanje okolja dinamičnih vibracij vzorca in (na podlagi tega) za izbiro ustrezne preskusne metode. Čeprav je prvotno namenjen elektrotehničnim primerkom, ta standard ni omejen nanje in se lahko poljubno uporablja na drugih področjih (glej dodatek A).
