2. Balancing criteria
Every time an industrial control operation is carried out, the result must be compared with a criterion. The same applies to balancing. Machine construction standards and codes (or contracts) lay down criteria. Some examples are given below.
2.1 Residual unbalance
-
The ISO 1940-1 standard, which is general for all types of machine, but relates to rigid rotors, gives balancing classes, such as :

G 40 for car wheels, engine crankshafts ;
G 16 for propeller shafts ;
