1 Scope 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.

What is BS ISO 21940-11 - Procedures and tolerances for rotors about? Rotor balancing is a procedure by which the mass distribution of a rotor is checked and, as necessary, adjusted to ensure the unbalance tolerance is met. BS ISO 21940-11:2016+A1:2022 establishes procedures and unbalance tolerances for balancing rotors with rigid behaviour, providing guidance on the magnitude of the permissible residual unbalance for a range of machine types. Who is BS ISO 21940-11 - Procedures and tolerances for rotors for? BS ISO 21940-11 applies in a wide range of rotating machine design, construction and operation industries and is written for engineers and balance machine operators in balancing test facilities. What does BS ISO 21940-11 - Procedures and tolerances for rotors cover? It establishes procedures and unbalance tolerances for balancing rotors with rigid behaviour. It specifies: The magnitude of the permissible residual unbalance The necessary number of correction planes The allocation of the permissible re...

ISO 21940-11:2016 establishes procedures and unbalance tolerances for balancing rotors with rigid behaviour. It specifies a) the magnitude of the permissible residual unbalance, b) the necessary number of correction planes, c) the allocation of the permissible residual unbalance to the tolerance planes, and d) how to account for errors in the balancing process. NOTE In ISO 21940‑14, the assessment of balancing errors is considered in detail. Fundamentals of rotor balancing are contained in ISO 19499 which gives an introduction to balancing. ISO 21940-11:2016 does not cover the balancing of rotors with flexible behaviour. Procedures and tolerances for rotors with flexible behaviour are dealt with in ISO 21940‑12.
