1975-01-01
HISTORICAL
ARP588A
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.

Balancing Machines - Description and Evaluation Horizontal, Two-Plane, Soft-Bearing Type for Gas Turbine Rotors

CURRENT
ARP587C
The specific performance requirements preceding each test in Section 9 have been written to define certain characteristics of the machine. Conformance with the tests constitutes what is considered minimum proof that the machine will meet these requirements. The test procedures will not prove conformance with all requirements over the full range of all variables, neither will they measure nor define the exact reasons for nonconformance in a given test. Failure of a machine to conform may be due to shortcomings in specific components or to more general reasons such as lack of ruggedness, improper leveling or anchoring to the floor, etc.
