7. Measurement Evaluation with Standard Values
To be able to derive statements from the measured vibration velocity values about the condition of a machine, experience is necessary. If experienced
personnel are not available, in many cases one can refer to the ISO 10816 recommendations. In these sections of the standard, the vibration severity zone
limits for various machine types are defined, which can provide an initial evaluation of a machines maintenance condition.The four zone boundary limits
characterize the machine in categories according to vibration severity:
A: New condition
B: Good condition for unrestricted continuous operation
C: Poor condition - allows restricted continued operation only
D: Critical condition - Danger of damage to the machine.

Table 1:Typical zone limit values for vibration severity according to ISO 10816-1
In the standard it is pointed out that small machines, for example electric motors with a power rating of up to 15 kW, tend to lie around the lower zone limits,
whereas large machines, for example motors with flexible foundations, lie around the upper zone limits.
