Table derived from data where class B angular tolerance is listed as 0.75°, 0.5°, 0.33° for ranges 0-400, >400-1000, >1000 respectively, converted to mm/m using the tangent of these angles. When a drawing specifies , it is referring

For angular dimensions, the tolerance is expressed as a deviation of the shorter side (in mm) over a given length. This is equivalent to a tolerance on the angle itself, which varies with length.
