ISO 2768-2: Geometrical tolerances for features (such as flatness, symmetry, and circularity). The Core Benefits of Using ISO 2768
Simplified Drawings: By referencing ISO 2768 in the title block, designers can focus only on "critical" dimensions that require tighter control.Cost Efficiency: Manufacturing parts to unnecessarily tight tolerances increases costs. ISO 2768 provides realistic, "workable" ranges for non-critical features.Global Consistency: Since it is an international standard, a drawing made in Europe can be interpreted accurately by a machine shop in Asia or North America.Ease of Inspection: Quality control teams can quickly determine if a part is within acceptable limits using standardized tables.

In this example:"m" refers to the medium class for linear dimensions (Part 1)."k" refers to the medium class for geometrical tolerances (Part 2). Common Misconceptions and Best Practices ISO 2768-2: Geometrical tolerances for features (such as
