General Tolerances According to ISO 2768: A Comprehensive Guide

Limitations and risks

The ISO 2768 standard is divided into two distinct parts, each addressing a specific category of deviations.

This paper provides a comprehensive technical analysis of the ISO 2768 standard, which defines general tolerances for linear and angular dimensions and geometrical tolerances. While the technical application of these standards is widely understood in mechanical engineering, the dissemination of the documents themselves remains a point of contention regarding copyright and exclusivity. This paper explores the bifurcation of the standard into Part 1 (General Tolerances for Linear and Angular Dimensions) and Part 2 (Geometrical Tolerances), details the economic advantages of using general tolerances, and addresses the "exclusive" nature of official PDF distribution versus the public interest in standardization.
