Table 4-5. UNFILTERED
VIBRATION LIMITS
RESILIENTLY MOUNTED MACHINES
RPM † Limit (inch) Limit (metric) Characteristics
1200 & above 0.15 in/sec pk 2.7 mm/sec rms Constant velocity
Below 1200 2.4 mils pk-pk 0.061 mm pk-pk Constant displacement
† For IEC Standard 60034-14 use constant displacement below 600 rpm and constant velocity
at or above 600 rpm.
Note: For machines with rigid mounting, multiply the limiting values by 0.8.
