: The standard focuses on individual tooth deviations, including: Profile Deviation ( cap F sub alpha

Quality control labs mirror their coordinate measuring machine (CMM) reports directly after the definitions stated in the JIS PDF.

Adherence to JIS B 1702-1:2016 allows manufacturers to communicate precision levels clearly using a globally recognized ISO-aligned language. This standardization is essential for the design of high-performance spur and helical gears in modern engineering. JIS B 1702-1:2016 - Cylindrical gears - ANSI Webstore jis b 1702-1 pdf

. It measures three critical deviations that can make or break a machine's performance: Single Pitch Deviation ( f sub p t end-sub
