This SAE Aerospace Recommended Practice (ARP) specifies the requirements of balancing machines that make them suitable for the subject class of work. It was developed for soft-bearing balancing machines but may also be used for hard-bearing machines until ARP4050 is issued for that type of machine.

This ARP specifies those requirements of balancing equipment which make it suitable for the subject class of work. It specifies: a Sensitivity b Accuracy of indication of amount and angle of unbalance. c Ability to measure static unbalance unaffected by couple unbalance. d Machine capacity relating to weight and physical dimensions of the rotors which can be balanced. e Balancing speed of rotation. f Standard balancing machine drive adapter flange dimensions. g Power requirements.
