SCOPE
This standard provides evaluation methods for double flank testers used for radial composite measurement of gears. Recommendations are given for use of artifacts. Annex A is informative and provides methods for estimating uncertainty.  Annex B is normative and provides requirements for artifact calibration certificates.

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 ANSI/AGMA 2116-A05, Evaluation of Double Flank Testers for Radial Composite Measurement of Gears.]

Between 1994 and 1998, AGMA published three standards on calibration of gear measuring instruments: ANSI/AGMA 2010-A94, Measuring Instrument Calibration –Part I, Involute Measurement, ANSI/AGMA 2113-A97, Measuring Instrument Calibration, Gear Tooth Alignment Measurement, and ANSI/AGMA 2114-A98, Measuring Instrument Calibration, Gear Pitch and Runout Measurements. These standards covered elemental measurements specified in the accuracy requirements of ANSI/AGMA 2015-1-A01, Accuracy Classification System - Tangential Measurements for Cylindrical Gears. The Calibration Committee decided that supplemental information, on measurement system conditions for calibration, accuracy requirements and uncertainty determination, was desirable to have in an Information Sheet, AGMA 931-A02, Calibration of Gear Measuring Instruments and Their Application to the Inspection of Product Gears, that was published in 2002.

The material in these AGMA documents was combined and submitted to ISO for the development of ISO 18653:2003, Gears - Evaluation of instruments for the measurement of gears, and ISO/TR 10064-5:2005, Cylindrical gears - Code of inspection practice - Part 5: Recommendations relative to evaluation of gear measuring instruments.

The Calibration Committee decided that similar standardization and information was needed for the evaluation methods of double flank testers used for radial composite measurement of gears. After a study of existing practices, standards, and literature the information contained herein is a consolidation of the most common methods currently in existence.

The first draft of ANSI/AGMA 2116-A05 was made in August, 2003. It was approved by the AGMA membership in October, 2005.  It was approved as an American National Standard on December 29, 2005.
