ISO/TR 10064-6:2009 provides information on measuring methods and practices of unassembled bevel and hypoid gears and gear pairs. It includes methods and practices, which permit the manufacturer and purchaser to conduct measuring procedures which are accurate and repeatable to a degree compatible with the specified tolerance grade of ISO 17485.

Tolerances are given in Clause 5 of ISO 17485:2006, for calculating the maximum values allowed by the specific tolerance grade. Required and optional measuring methods are provided in Clause 6 of ISO 17485:2006.

ISO/TR 10064-6:2009 applies to bevel gear components as defined in ISO 17485. It does not apply to enclosed gear unit assemblies, including speed reducers or increasers, gear motors, shaft mounted reducers, high speed units, or other enclosed gear units which are manufactured for a given power, speed, ratio or application.
