BS ISO 21940-14:2012+A1:2022

Mechanical vibration. Rotor balancing. Procedures for assessing balance errors | Status: Current, Under review

1 Scope This part of ISO 21940 specifies the requirements for the following:

1. a) identifying errors in the unbalance measuring process of a rotor;
2. b) assessing the identified errors;
3. 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.
