In simpler terms, ISO 2768 applies to dimensions that do not have a specific tolerance written next to them (e.g., a dimension written simply as "50" rather than "50 ± 0.1").
The code “MK” actually combines a class from Part 1 (M – Medium) and a class from Part 2 (K – for geometrical tolerances).
(mm)
Never assume “Medium is always ±0.2”. It changes with size. Always refer to your printed Tolerance ISO 2768 MK PDF reference sheet.

You use ISO 2768 when a drawing dimension does have a specific tolerance written next to it (e.g., ±0.1 mm). Instead, the general tolerance applies to all such untoleranced dimensions, as stated in a general note on the drawing. In simpler terms, ISO 2768 applies to dimensions
