The primary driver for the adoption of ISO 2768 is economic efficiency.
ISO 2768 is an international standard that specifies general tolerances for linear and angular dimensions. The standard provides a set of tolerance classes, which define the acceptable limits of variation for dimensions. The tolerances are applicable to various features such as lengths, widths, heights, diameters, and angles. The standard is widely used in various industries, including mechanical engineering, aerospace, and construction.
The standard provides a globally recognized framework for general tolerances in engineering drawings . Its primary purpose is to simplify technical drawings by setting default permissible variations for dimensions and features that do not have specific, individual tolerance indications.
