適用范圍：This part of IEC 60068 is intended for general application for testing specimens whensimulation 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 specifiedmixed mode excitation without unacceptable degradation of its functional and/or structuralperformance. It is particularly useful for tailoring mixed mode environments where measureddata 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 inspecified performances, and to use this information, in conjunction with the relevantspecification, to assess the acceptability of specimens. In some cases, this standard may alsobe used to demonstrate the mechanical robustness of specimens.This standard is applicable to specimens which may be subjected to vibration of a randomand/or a combination of random and deterministic nature resulting from transportation or reallife environments, for example in aircraft, space vehicles and for items in their transportationcontainer when the latter may be considered as part of the specimen itself.Although primarily intended for electrotechnical specimens, this standard is not restricted tosuch specimens and may be used in other fields where desired.
