scope:

This Japanese Industrial Standard specifies the evaluation methods for measurement accuracy in double flank testers which evaluate the double flank radial composite deviations and the tight mesh centre distances of a pair of involute cylindrical gears, using an artifact for test. This Standard also specifies the acceptance tests to verify the conformance of the performance of double flank tester to the requirements, using an artifact for test.

This Standard is applicable to periodic tests to verify the performances of double flank tester.
