适用范围：This part of IEC 60068 demonstrates the adequacy of specimens to resist dynamic loadswithout unacceptable degradation of its functional and/or structural integrity when subjectedto the specified random vibration test requirements.Broadband random vibration may be used to identify accumulated stress effects and theresulting mechanical weakness and degradation in the specified performance. Thisinformation, in conjunction with the relevant specification, may be used to assess theacceptability of specimens.This standard is applicable to specimens which may be subjected to vibration of a stochasticnature resulting from transportation or operational environments, for example in aircraft,space vehicles and land vehicles. It is primarily intended for unpackaged specimens, and foritems in their transportation container when the latter may be considered as part of thespecimen itself. However, if the item is packaged, then the item itself is referred to as aproduct and the item and its packaging together are referred to as a test specimen. Thisstandard may be used in conjunction with IEC 60068-2-47:2005, for testing packagedproducts.If the specimens are subjected to vibration of a combination of random and deterministicnature resulting from transportation or real life environments, for example in aircraft, spacevehicles and for items in their transportation container, testing with pure random may not besufficient. See IEC 60068-3-8:2003 for estimating the dynamic vibration environment of thespecimen and based on that, selecting the appropriate test method.Although primarily intended for electrotechnical specimens, this standard is not restricted tothem and may be used in other fields where desired (see Annex A).
