Scope

This Part provides two standard test methods (method 1 and method 2) for determining
the ability of a specimen to withstand specified severities of broad-band random
vibration. Neither test method can be considered more severe than the other, the
difference being primarily that method 2 provides more information to quantify the
applied test, and is therefore more reproducible.
It is also to reveal the accumulated effects of stress induced by random vibration, and
the resulting mechanical weakness and degradation in specified performance and to
use this information, in conjunction with the relevant specification, to assess the
acceptability of specimens. In some cases. this Part may also be used to demonstrate
the mechanical robustness of specimens and/or to study their dynamic behavior...
This Part is applicable to specimens which may be subjected to vibration of a random
nature resulting from transportation or operational environments, for example in aircraft,
space vehicles and land vehicles. It 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.
Although primarily intended for electrotechnical products, this Part is not restricted to
them and may be used in other fields where desired.

Summary	This standard provides two standard test method (Method 1 and Method 2) to determine the test sample subjected to a specified band random vibration. Can not be considered an experimental approach than other more severe test method, the main difference is the Test Method 2 provides additional information to quantify the test applied, it has a better reproducibility. This standard also reveals random vibration caused by the cumulative effects of stress and specific mechanical performance, and the use of such information and related specifications to assess the acceptability of the test sample. Sometimes, this standard is also used to demonstrate the adaptability of mechanical environmental samples and/or study their dynamics. This standard applies to the transport or work environment may be subject to random vibration of the sample, as in aircraft, spacecraft and land transport modes, it is mainly used without packaging samples, as well as its packaging during transport as part of test sample itself sample. This standard applies to electrical and electronic products, but is not limited to this, also applicable to other areas of the product.
