This Standard specifies the evaluation methods of instruments used for gear measurements of involute, helix, pitch and tooth space runout by using the gear shape artifacts.

It is also applicable both to instruments that measure the tooth space run out directly and to those that compute it from index measurements of tooth flank.

It also gives recommendations for the evaluation of tooth thickness measurement instruments.

This Standard includes the estimation of measurement uncertainty of instruments.

However, it does not address the calibration of artifacts by laboratories accredited in accordance with JIS Q 17025, or its requirements are not intended as an acceptance specification of product gears.

The estimation of measurement uncertainty of product gears is beyond the scope.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 18653: 2003 Gears-Evaluation of instruments for the measurement of individual gears (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
