Permissible residual specific unbalance based on balance quality grade G and service speed n
Experimental evaluation
Experimental evaluation of the balance quality requirements is often carried out for mass production applications. Tests are commonly performed in situ. The permissible residual unbalance is determined by introducing various test unbalances successively in each correction plane, based on the most representative
criterion (e.g. vibration, force, noise caused by unbalance).
In two-plane balancing, if no tolerance planes (as specified in 4.4) are used, the different effects of unbalances with the same phase angle and of those 180 apart shall be taken into account.
