GB/T 13319-2020 Geometrical product specifications(GPS)—Geometrical tolerancing—Pattern and combined geometrical specification
Abstract
This standard establishes supplementary rules for GB/T 1182 for the use of symbols for position tolerance, symmetry, line profile, and surface profile, as well as linearity symbols (when the measured element is nominally coaxial) and flatness symbols (when the measured element is nominally coplanar). It can be used in combination with grouping specifications listed in Appendix C or to define individual specifications.
These rules apply to tolerance zones groups that use modifiers CZ, CZR, or SIM combined with position or direction constraints.
This standard does not include the use of grouping specifications that apply minimum entity requirements and maximum entity requirements (see GB/T 16671).
This standard does not include the construction of common reference bases based on grouped elements (see GB/T 17851).
