Vibration Measurement Instruments

ISO standard 10816-3

The ISO standard 10816-3 classifies machines differently according to whether the machines are considered 

to be flexibly or rigidly mounted. This reflects the location of the machines stiff body resonances related to 

the basic running speed of the machine.

For instance, a machine supported by rubber or spring has resonances at low running speeds. The machine 

starts to vibrate at certain low revolutions. When the speed is increased above these resonance frequencies, 

the vibration is reduced. This machine is considered flexible.

Modern machines that have high RPM’s and flexible bearing supports and foundations can be treated as 

flexible, even when they are not mounted on rubber or springs.
