ISO 2768 is an international standard that provides general tolerances for linear dimensions, angular dimensions, and geometrical tolerances in engineering drawings. It aims to simplify the specification of tolerances by offering a set of predefined values, which helps in reducing the complexity of technical documentation. The standard is divided into two parts: ISO 2768-1 covers general tolerances for linear and angular dimensions, while ISO 2768-2 addresses geometrical tolerances. By using ISO 2768, engineers and manufacturers can ensure consistency and accuracy in the production process, ultimately improving the quality of the final product.
