2768 Medium: Iso

"ISO 2768 medium" refers to a standard tolerance for linear dimensions, which is a part of the ISO 2768 standard. This standard provides general tolerances for linear and angular dimensions, as well as geometric tolerances, for various engineering and manufacturing applications.

ISO 2768 was withdrawn and replaced in part by ISO 22081:2021 for geometrical tolerances, but ISO 2768-1 (linear & angular) remains widely used in practice. Many companies continue referencing ISO 2768-m for simplicity. iso 2768 medium
