Inspection Practices – Part 2: Double Flank Radial Composite Measurements
This information sheet discusses inspection of cylindrical involute gears using the radial (double flank) composite method, with recommended practices detailed. This information sheet is a supplement to the standard ANSI/AGMA 2015-2.
This information sheet constitutes a code of practice dealing with inspection relevant to radial composite deviations of gears when measurements are made by using a master gear in double flank contact.
In providing advice on gear checking methods and the analysis of measurement results, it supplements standard ANSI/AGMA 2015-2.
NOTE: Measurements by using a master gear in single flank contact are not covered by this information sheet. See ANSI/AGMA/ISO 1328-1  and ISO/TR 10064-1 , for more information on single flank testing.

AGMA 915-2-A05 replaced AGMA ISO 10064-2, Cylindrical Gears – Code of Inspection Practice – Part 2: Inspection Related to Radial Composite Deviations, Runout, Tooth Thickness and Backlash, and the information on similar subjects as covered in AGMA 2000-A88, Gear Classification and Inspection Handbook – Tolerances and Measuring Methods for Unassembled Spur and Helical Gears.
The first draft of AGMA 915-2-A06 was made in March 1999. It was approved by the Technical Division Executive Committee (TDEC) in May 2005.
The AGMA 915-2-B20 revision replaces AGMA 915-2-A05 and was approved by the Technical Division Executive Committee (TDEC) on November 26, 2019. The main changes in this new revision include:
- Change of title;
- OLD - Inspection Practices - Part 2: Cylindrical Gears - Radial Measurements;
- NEW - Inspection Practices – Part 2: Double Flank Radial Composite Measurements;
- Addition of other types of gears including bevel gears;
- Information on the measurement of double flank runout, eccentricity, functional tooth thickness and higher order Fourier Analysis;
- Design of suitable master gears, statistical measurement techniques related to the use of double flank testers, gage repeatability and reproducibility and uncertainty analysis.
