The DIN 5480 standard specifies based on a 30° pressure angle. This design relies on a true involute profile, which allows for high torque transmission, excellent centering capabilities, and smooth load distribution across the gear teeth.
The standard is published by (DIN's official publisher). As of 2024:

DIN 5480 is a German Institute for Standardization (Deutsches Institut für Normung) standard that defines based on reference diameters. Unlike older systems (like DIN 5462 or DIN 5463) which used a straight-sided tooth profile, DIN 5480 uses an involute profile.
This foundational part outlines the basic concepts, the reference profile, modules, nominal diameters, and the combination of tolerances. The DIN 5480 standard specifies based on a
