Foreword
Introduction
1 Scope
2 Normative references
3 Terms and definitions
4 Pertinent aspects of balancing
5 Similarity considerations
6 Specification of unbalance tolerances
7 Allocation of permissible residual unbalance
   to tolerance planes

   planes
9 Assembled rotors
10 Accounting for errors in the verification of permissible
   residual unbalances
Annex A (informative) - Example of the specification of
        permissible residual unbalance based on balance
        quality grade G and allocation to the tolerance planes
Annex B (informative) - Specification of unbalance tolerances
        based on bearing force limits
Annex C (informative) - Specification of unbalance tolerances
        based on established experience
Annex D (informative) - Rules for allocating unbalance tolerances
        from tolerance planes to correction planes
