For , the standard defines specific tolerances that are independent of length:
Practical Example: A 150mm long block machined flat does not need a flatness symbol. Under ISO 2768-K, its surface cannot deviate more than 0.2mm from perfect flatness.
It means:
The uppercase refers to ISO 2768-2 (General tolerances for geometrical tolerances). This part covers characteristics like straightness, flatness, perpendicularity, and symmetry.
These are also controlled by ISO 2768-2. For symmetry, the tolerance is the same as for perpendicularity, with class K allowing a deviation of 0.2 mm for nominal lengths up to 100 mm. Tolerance Iso 2768 Mk Pdf

When a drawing specifies , it means the manufacturer must adhere to the Medium (m) class for linear/angular dimensions and the K class for geometrical tolerances. Breaking Down the "m" and "k" in ISO 2768-mk
Meet Alex, a young engineer working for a company that produces precision machinery. Alex's team was tasked with designing and manufacturing a critical component for a high-stakes project. The client required a very specific set of tolerances to ensure the component would fit perfectly into the larger assembly. The Tolerance ISO 2768 MK PDF is significant
| Shorter Side Range | Tolerance | |--------------------|-----------| | ≤ 100 | 0.2 | | >100 to 300 | 0.3 | | >300 to 1000 | 0.4 | | >1000 to 3000 | 0.5 |
Refers to ISO 2768-2, tolerance class 'K' for general geometrical tolerances.
