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..
