BS ISO 21940-11:2016+A1:2022 PDF

Scope: 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...
