Establishes a classification system for the geometrical accuracy specification of wormgearing. It also provides uniform measurement procedures including discussions on single and double flank composite testing and tooth thickness measurements. The standard establishes ten accuracy grades based on the relative effect of geometrical errors on conjugate action for wormgear sets. (Metric edition of ANSI/AGMA 2011-A98).
