This part of ISO 21940 specifies the requirements for the following:<\/p>\n
identifying errors in the unbalance measuring process of a rotor;<\/p>\n<\/li>\n
assessing the identified errors;<\/p>\n<\/li>\n
taking the errors into account.<\/p>\n<\/li>\n<\/ol>\n
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.<\/p>\n
For the main typical errors, this part of ISO 21940 lists methods for their reduction in an informative annex.<\/p>\n
