Iso 2768 General Tolerances Pdf Exclusive May 2026

Below is the exclusive breakdown of permissible deviations in mm. Note how tolerance increases with nominal size.

Part 1 establishes general tolerances for linear dimensions (e.g., lengths, widths, diameters) and angular dimensions (e.g., angles). The standard simplifies drawing notation by allowing the designer to specify a tolerance class in the title block of the drawing rather than next to each dimension. iso 2768 general tolerances pdf exclusive
