This applies to the alignment of the tooth along its axis (crucial for helical gears).
Before searching for papers, it is useful to know exactly what the standard covers to ensure you are looking at the right document.
If you are currently using a scanned PDF from 1998, beware of these changes in the current revision (JIS B 1702-1:2015):
Absolutely. Whether you are a design engineer checking backlash or a QC inspector logging final inspection reports, JIS B 1702-1 is the definitive rulebook for cylindrical gears in Asia.
However, do not waste months searching for a "free" version that is likely broken or illegal. Consider the PDF purchase an insurance policy against manufacturing defects.
