This standard describes potential coupling unbalance and identifies its sources. The standard breaks down the
requirements into usable groups and outlines how to calculate the potential unbalance of the coupling. Calcula-
tions are based on SI units of the metric system. The AGMA method of computing coupling potential unbalance
is provided. A guide is provided for balance class selection for purchasers who have not defined the coupling
balancing requirements for their system.
