1 Scope

This standard specifies the evaluation method for measuring the gear involute, spiral, pitch and radial runout. It is also suitable for direct measurement.

The amount of radial runout and the instrument using the indexing method to calculate the radial runout. In addition, the evaluation method of the tooth thickness measuring instrument is recommended, including

Evaluation method for measurement uncertainty using calibration templates. This standard does not include calibration of laboratory samples that require ISO /IEC 17025 approval.

Requirements; not as acceptance specifications for product gears (see ISO 1328-1, ISO 1328-2, ISO /T R10064-1 and ISO /T R10064-2);

Not applicable to the assessment of product gear measurement uncertainty (see ISO /T R10064-5 for this assessment).
