This part of ISO 21940 specifies the requirements for the following:
a) identifying errors in the unbalance measuring process of a rotor;
b) assessing the identified errors;
c) taking the errors into account.
This part of ISO 21940 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 ISO 21940 lists methods for their reduction in an informative annex.
