Note: These values are typical approximations for linear dimensions; refer to the official standard for the full matrix covering all dimensions and specific material groups. Selection Process

If no individual tolerance is specified on a drawing, the standard applies "general tolerances" based on the selected TG to ensure all features are controlled. Factors Affecting Tolerance Selection

and provides a structured approach to tolerancing based on material properties and manufacturing complexity. Super-Ingenuity Core Tolerance Framework The standard uses Tolerance Grades (TG)

| Tolerance Class | Permissible Deviation (mm per 100mm length) | | :--- | :--- | | Fine (f) | ± 0.3 mm/m | | Medium (m) | ± 0.5 mm/m | | Coarse (c) | ± 1.0 mm/m |
