This part of IEC 60068 is 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.
