To evaluate the vibration velocity, the measuring equipment must meet the requirements of
ISO 2954.
Select the measuring locations according to ISO 10816-1, Section 3.2.
The vibration acceleration is evaluated in the frequency range from 10 Hz to 2000 Hz. The
maximum peak in the measurement time range is considered.
The vibration values must not exceed the specified limits at any measuring location.
