Mk Verified — Norme Iso 2768
The designation refers to a combination of two specific tolerance grades:
However, ISO 2768-mK is not a universal panacea. It is explicitly not intended for certain features. The standard excludes tolerances for chamfer angularity, fillet radii, or dimensions that are inherently dependent on other features (e.g., angular relationships from a datum). Furthermore, “mK” is inadequate for high-precision industries like aerospace or medical devices, where finer classes (like ISO 2768-fH) or fully defined individual tolerances are mandatory. norme iso 2768 mk
