represents higher precision (e.g., A2 is more precise than A11), which is the opposite of the previous Q-grade system. Measurement Scope: agma 20151a01 pdf
that established an accuracy classification system for tangential measurements of cylindrical gears. While it was a groundbreaking document that unified North American and international gear standards, it is now considered and has been superseded by newer ISO-aligned standards.

What is AGMA 2015-1-A01?
Medium Accuracy (A6–A9): Requires cumulative pitch, single pitch, total profile, and lead. "AGMA 20151-A01 gear noise standard summary" (0
This standard establishes a system for classifying the accuracy of cylindrical involute gears (spur and helical) based on tangential measurements of their flanks. It provides: AGMA 2015-1-A01 - Accuris Standards Store
Functional Accuracy: By emphasizing tangential measurements, it provides a better prediction of a gear’s transmission error, which is the primary cause of gear noise and vibration.
