Used for structural components where fit is not critical. Table 1: Linear Dimensions (mm) Nominal Size (mm) m (Medium) c (Coarse) v (Very Coarse) 120 to 400 Part 2: ISO 2768-2 (Geometrical Tolerances)
While the official full-text standard is a paid document, many manufacturers and engineering hubs provide summary tables and PDF guides for reference: Official Standard: You can purchase the current version directly from the ISO 2768-1 Official Page Technical Guides: Sites like 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.). Used for structural components where fit is not critical
Given a , tolerance class (f, m, c, v), and type of dimension (linear, external radius, chamfer height, or angular), the tool automatically outputs the standard tolerance value as defined in ISO 2768-1 (for linear/angular) and ISO 2768-2 (for geometrical tolerances). Part 2 deals with "geometry" (flatness
