This International Standard defines the basis for specifying the rules to be employed in evaluating the mechanical vibration of machines in the operating range 10 to 200 rev/s in such a way that comparison is possible with similar measurements obtained from other like machines.
The purpose of the rules is to evaluate the vibration of "normal" machines with respect to reliability, safety and human perception. It is not intended to apply to the evaluation of vibration of machines with respect to noise control, or in general, to unusual or special purpose machines which are not normally produced in significant quantities, or to machines requiring the study or analysis of vibration characteristics. These latter cases will generally require specific diagnostic treatment, and include a broader frequency range and more specialized instrumentation than considered necessary for the purpose of these general recom mendations.
The val id i ty of the rules is restricted to vibrations measured at machine surfaces, such as bearing caps, and within the frequency range 10 to 1 000 Hz and the speed range 10 to 200 rev/s. Where the aim is to evaluate specific machines, range classification levels may be specified in accordance with the rules established in this International Standard.
This International Standard includes an explanation of terms, guidance on measuring conditions and a table of preferred vibration severity ranges. Examples of a recommended method of classification are given in annex A and the rules for converting rms-velocity values to peak-dispiacement amplitudes are given in annex B.
