The standard provides four classes of tolerances:
General circular run-out tolerances are typically equal to the circularity tolerance but capped by radial run-out limits. General Tolerance - ISO 2768 1 & 2 - ZEISS Quality Forum iso 2768 general tolerances pdf exclusive
Focuses on linear and angular dimensions, such as lengths, diameters, radii, and chamfer heights. It defines four tolerance classes: f (fine): For high-precision components. m (medium): The most common class for standard machining. c (coarse): For parts where high precision is not critical.
