The ISO standard provides vibration limits for general machinery in velocity and displacement units, based on machine size (above or below 300 kilowatts/400 horsepower, or above or below shaft height of 315 millimeters /12.4 inches) and mounting (rigid or flexible). For most rotodynamic pumps, vibration limits are given in velocity …

Typical sources of vibration produced within the alternator can be attributed to rotating system imbalance, misalignment and fan blade pass frequency. These translate into linear vibrations in the x (longitudinal), y (vertical) and z (transverse) directions. Table 1 shows the linear vibration level limits recommended for alternators in ISO 8528-9.

At any speed greater than max continuous speed, up to and including trip speed, the vibration shall not exceed 150% of the max value recorded at maximum continuous speed. Variable speed pumps shall operate over their specified speed range without exceeding the vibration limits stated for this standard. 1.6.1.

The limits are unevenly applied due to a focus on 25 micrometers (one mil) displacement, which is at odds with how alarms and trips are set. Field alarms and trips are based on a displacement that is inversely proportional to the square root of the speed per ISO 7919; in essence proportional to the square root of 12000/N.
