It provides proceduresfor the design, calibration, and traceability of involute, pin, and plane (flank) masters. It
10、also covers condition evaluation of involute measuring instruments such as probe location, gain, hysteresis, etc. Recommendations are included for establishment of a proper environment and for statistical data evaluation procedures.
