ISO 2768 is an international standard published by the International Organization for Standardization (ISO) that specifies general tolerances for linear and angular dimensions. The standard provides a framework for defining the acceptable limits of variation in the dimensions of parts and components, ensuring that they can be manufactured and assembled with a high degree of accuracy.
When manufacturing parts, knowing the standard is just the first step. If you are preparing to send files for production, you can: Coarse) | ±3° | ±2° | ±1° |

Manufacturers must be aware of this transition. The 2025 version covers linear sizes from above 0.5mm up to 4000mm for four tolerance classes. PDF references for the 2025 draft are already available from various international standard bodies for review.
