Application Summary AI generated

This standard specifies methods for determining the permissible residual unbalance in rigid rotors, based on rotor mass, operating speed, and balance quality grades. It is applied in the design, manufacturing, and quality inspection of rotating machinery such as fans, pumps, turbines, and electric motor armatures. The standard ensures that rotors meet vibration and stability requirements during operation, reducing wear and noise in mechanical systems.
