This standard includes physical units and defines mathematical transformations for each category of vibration and shock data into a form suitable for quantitative comparison and quantitative specification between experiments. This standard applies to the analysis of steady or random vibrations and transient or continuous signals. Categories of signals are defined in Section 6. Especially in frequency domain analysis, special care is needed to correctly recognize the type of signal to be analyzed in order to use the correct conversions and units. Data can be obtained experimentally or from measurements of mechanical structures. It can be obtained from numerical simulation of mechanical structures. The category of this data is very broad, as it includes a variety of mechanical structures such as voice measurement devices, musical instruments, automobiles, manufacturing machines, buildings, and public facilities. These data can determine the response of a machine or person to mechanical vibration and shock.
