SCOPE
This information sheet constitutes a code of practice dealing with inspection relevant to radial composite deviations and runout of cylindrical involute gears; i.e., with measurements referred to double flank contact.

In providing advice on gear checking methods and the analysis of measurement results, it supplements standard ANSI/AGMA 2015-2-A06, where most of the terms used are defined.

FOREWORD
[The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of AGMA 915-2-A05, Inspection Practices – Part 2:  Cylindrical Gears – Radial Measurements.]

AGMA 915-2-A05 replaces 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 user of this Information Sheet is alerted that differences exist between AGMA 2000-A88, AGMA ISO 10064-2 and this document.  This includes that measuring methods refer to an accuracy grade numbering system that is reversed, such that the smallest number represents the smallest tolerance.  Therefore, the user of this information sheet must be very careful when comparing measurement methods formerly specified using AGMA 2000-A88 or AGMA ISO 10064-2.

The first draft of AGMA 915-2-A05 was made in March, 1999.  It was approved by the Technical Division Executive Committee (TDEC) in May, 2005.

Suggestions for improvement of this standard will be welcome.  They should be sent to the American Gear Manufacturers Association, 1001 N. Fairfax Street, Suite 500, Alexandria, Virginia  22314.
