This part of ISO21940 specifies the requirements for the following: identifying errors in the unbalance measuring process of a rotor; assessing the identified errors; taking the errors into account. This part of ISO21940 specifies balance acceptance criteria, in terms of residual unbalance, for both directly after balancing and for a subsequent check of the balance quality by the user. For the main typical errors, this part of ISO21940 lists methods for their reduction in an informative annex.
