ANSI/AGMA 2015-1-A01 defines gear accuracy classification for cylindrical gears, aligning U.S. standards with ISO 1328-1 while employing a reversed numbering system (A2–A11) for precision. A comprehensive report should detail the shift to line-fit analysis, technical scope (5–1000 teeth), and required companion documents for measurement. Preview the standard at ANSI Webstore .

The search for is a classic case of a misremembered standard number. The correct document you need is almost certainly AGMA 909-A01: Specifications for Plastic Gears , or its up-to-date replacement, AGMA 909-C16 . agma 20151a01 pdf
: Unlike radial (double-flank) measurements that check center-distance variation, this standard focuses on single-flank tangential measurements, which more closely simulate how gears actually mesh and transmit motion in a real-world gearbox. Preview the standard at ANSI Webstore
