ISO standard 10816-3 

The ISO standard 10816-3 classifies machines differently whether the machines are 
considered as flexible or rigid 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, have resonances at low running 
speeds. The machine starts 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.
