Application Summary AI generated
This standard specifies the design, metrological characteristics, and testing requirements for micrometers used to measure the root tangent length (base tangent length) of gear teeth. It is applied in precision manufacturing and quality control for cylindrical gears, particularly in automotive, aerospace, and machinery industries where gear accuracy is critical. The standard ensures consistent measurement of gear tooth thickness and backlash during production and inspection.
