external sizes, internal sizes, step sizes, diameters, radii, distances, external radii and chamfer heights for broken edges) ī) angular dimensions, including angular dimensions usually not indicated, e.g. ISO 2768 Part 1 only applies to the following dimensions which do not have an individual tolerance indication:Ī) linear dimensions (e.g. It applies to the dimensions of parts that are produced by metal removal or parts that are formed with sheet metal fabrication. ISO 2768 Part 1 is intended to simplify drawing indications and it specifies general tolerances for linear and angular dimensions without individual tolerance indications in four tolerance classes.
