General tolerances for angular dimensions apply to angles such as $90^\circ$, $60^\circ$, etc. The tolerance is expressed in minutes and degrees, depending on the length of the shorter leg of the angle.
Part 1 establishes four classes of tolerance, representing different levels of manufacturing precision. The choice of class depends on the production method and the industry sector.
The standard is divided into two distinct parts, each covering different types of tolerances: din iso 2768
Values for "v" (Very coarse) start at >3 mm.
ISO 2768-1-m
| Nominal Length Range (mm) | H | K | L | | :--- | :--- | :--- | :--- | | up to 10 | 0.02 | 0.05 | 0.1 | | >10 up to 30 | 0.05 | 0.1 | 0.2 | | >30 up to 100 | 0.1 | 0.2 | 0.4 | | >100 up to 300 | 0.2 | 0.4 | 0.8 | | >300 up to 1000 | 0.3 | 0.6 | 1.2 | | >1000 up to 3000 | 0.4 | 0.8 | 1.6 |
It is crucial to note that DIN ISO 2768 does apply to: General tolerances for angular dimensions apply to angles
