Table of Weight Tolerances
Metric Weight Tolerances
The table below is a listing of the tolerances of various classes of masses. The weight value can deviate above or
below the nominal value by the tolerance defined. To determine the tolerance of a mass, look at the denomination
or nominal value of the weight and the appropriate class you need.
Available Classes: Class 0 - Class 1 - Class 2 - Class E1 - Class E2 - Class F1
