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
