GB/T 4249-2009 Geometrical Product Specifications(GPS)—Tolerancing principle
Abstract
This standard specifies the principles for determining the relationship between dimensional tolerances (linear dimensions and angular dimensions) and geometric tolerances.
This standard applies to the dimensions, dimensional tolerances, and geometric tolerances marked in technical drawings and related documents, in order to determine the size, shape, orientation, and positional characteristics of the components of a part.
