Anotation

IEC 60068-2-80:2005 Intended for general application for testing specimens when simulation is required of vibration excitation of a complex and mixed nature. The purpose of the test is to demonstrate the adequacy of the specimen to resist the specified mixed mode excitation without unacceptable degradation of its functional and/or structural performance. It is particularly useful for tailoring mixed mode environments where measured data are available for the real life environment. The test also helps reveal the accumulated effects of stress induced by random vibration, mixed with sine and/or random, and the resulting mechanical weakness and degradation in specified performances, and to use this information, in conjunction with the relevant specification, to assess the acceptability of specimens. In some cases, this standard may also be used to demonstrate the mechanical robustness of specimens. This standard is applicable to specimens which may be subjected to vibration of a random and/or 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 when the latter may be considered as part of the specimen itself. Although primarily intended for electrotechnical specimens, this standard is not restricted to such specimens and may be used in other fields where desired. IEC 60068-2-80:2005 Destinee a une application generale aux essais des specimens lorsquune simulation dexcitation de vibrations complexes et mixtes est necessaire. Lobjectif de lessai est de prouver ladequation du specimen a resister aux excitations specifiees en mode mixte sans provoquer de degradation inacceptable de ses performances fonctionnelles et/ou structurelles. Cet essai est particulierement utile pour adapter des environnements en mode mixte a lenvironnement reel lorsque les donnees mesurees sont disponibles. Lessai permet egalement de reveler les effets accumules des contraintes induites par les vibrations aleatoires, combinees sinus et/ou bruit, ainsi que la faiblesse et la degradation mecaniques qui en resultent au niveau de la performance specifiee, et dutiliser ces informations associees aux specifications particulieres pour evaluer lacceptabilite des specimens. Dans certains cas, la presente norme peut egalement servir a prouver la robustesse mecanique des specimens. La presente norme sapplique a des specimens qui peuvent etre soumis a des vibrations aleatoires et/ou a une combinaison de vibrations aleatoires et deterministes dues a lenvironnement de transport ou a lenvironnement reel, par exemple dans les avions ou les vehicules spatiaux ou dans les elements du conteneur de transport lorsque celui-ci est considere comme partie integrante du specimen. Bien quelle soit principalement destinee aux specimens electrotechniques, la presente norme ne se limite pas a ces derniers et peut etre utilisee dans dautres domaines le cas echeant.
