This Standard 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.<\/p>\n
\nBroadband random vibration may be used to identify accumulated stress effects and the resulting mechanical weakness and degradation in the specified performance.<\/p>\n
\nThis information, in conjunction with the relevant specification, may be used to assess the acceptability of specimens.<\/p>\n
\nThis 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.<\/p>\n
\nIt 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.<\/p>\n
\nHowever, 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.<\/p>\n
\nThis Standard may be used in conjunction with JIS C 60068-2-47, for testing packaged products.<\/p>\n
\nIf 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.<\/p>\n
\nSee JIS C 60068-3-8 for estimating the dynamic vibration environment of the specimen and based on that, selecting the appropriate test method.<\/p>\n
\nAlthough primarily intended for electrotechnical specimens, this Standard is not restricted to them and may be used in other fields where desired (see Annex A).<\/p>\n
