This standard specifies methods and criteria for balancing flexible rotors, which operate above their first bending critical speed. It is applied in the design, manufacturing, and maintenance of high-speed rotating machinery such as steam turbines, gas turbines, and large compressors. The standard provides procedures for determining balance correction planes and acceptable residual unbalance levels to ensure safe and reliable operation.
