| Intervallo dimensionale (mm) | Tolleranza (mm) | | :--------------------------: | :-------------: | | 0 a 3 | ±0,1 | | 3 a 6 | ±0,2 | | 6 a 30 | ±0,3 | | 30 a 120 | ±0,5 | | 120 a 400 | ±0,8 | | 400 a 1000 | ±1,2 |
The standard is based on the concept of " general tolerances", which are applied to linear and angular dimensions without individual tolerance indications. The goal is to provide a set of standard tolerances that can be used for general-purpose designs, reducing the need for detailed tolerancing. tolleranze iso 2768 mk
Although not part of the MK section, it's essential to mention that the standard also defines geometric tolerances for features such as: | Intervallo dimensionale (mm) | Tolleranza (mm) |
For a drawing marked with , the permissible deviations (in mm) depend on the nominal size of the dimension: What Is ISO 2768? Complete Guide to Standard Tolerances Complete Guide to Standard Tolerances
