For linear dimensions, there are four tolerance classes. If a drawing applies this standard, it must be indicated near the title block (e.g., ISO 2768-m Class Designation Description Recommended Usage Precision machining General machining (most common) Casting or rough fabrication Very Coarse Large, non-critical parts Common Linear Tolerance Values (mm) Deviations depend on the nominal length of the feature: 0.5 to 3 mm: plus or minus 0.05 plus or minus 0.1 3 to 6 mm: plus or minus 0.05 plus or minus 0.1 30 to 120 mm: plus or minus 0.15 plus or minus 0.3 400 to 1000 mm: plus or minus 0.3 plus or minus 0.8 Reference Resources (PDF Guides)

While many websites offer free "cheat sheets," the official ISO 2768 document is copyrighted. You must purchase the full standard from the ISO store or your national standards body (e.g., ANSI in the US, BSI in the UK, DIN in Germany) for legal, certified use in auditing or legal disputes.

For radii (R) and chamfer heights (h), the tolerances are slightly different: Iso 2768 General Tolerances Pdf

While Part 1 deals with "size" (how long or wide something is), Part 2 deals with "geometry" (flatness, straightness, perpendicularity, etc.).

Yes, but typically use coarse (c) or very coarse (v) classes. Bending tolerances often exceed the standard.
