ISO 2768‑m / General Tolerance Guidance

Abstract

ISO 2768 is a standard providing general tolerances for linear and angular dimensions on technical drawings when no specific tolerance is indicated. This paper explains the scope and purpose of ISO 2768, details the tolerance classes (f, m, c, v), focuses on the “m” (medium) grade for machining (ISO 2768‑m), discusses the interpretation and application of ISO 2768‑m for linear, angular, and geometric features, shows worked examples and charts, comments on limitations and best practices, and compares ISO 2768 with other tolerance systems. Practical recommendations and a sample tolerance chart for ISO 2768‑m are included.

The ISO 2768-MH tolerance chart is a part of the ISO 2768 standard, which was first published in 1989 by the International Organization for Standardization (ISO). The standard provides general tolerances for linear and angular dimensions, and it is widely used in various industries, including engineering, manufacturing, and construction.
