GB/T 13319-2020 Geometrical product specifications (GPS)—Geometrical tolerancing—Pattern and combined geometrical specification

Scope: This standard is for geometry using position degree, symmetry degree, line profile degree and surface profile degree symbols, straightness symbol (when the measured element is nominally coaxial) and flatness symbol (when the measured element is nominally coplanar) The specification establishes the supplementary rules of GB/T 1182, which can be used for group specifications as listed in Appendix C or to define combination rules for individual specifications. These rules apply to tolerance zone groups grouped together using the modifiers CZ, CZR, or SIM and containing position or orientation constraints. This standard does not cover the use of group specifications that apply minimum and maximum physical requirements (see GB/T 16671). This standard does not include the method of constructing public benchmarks based on group elements (see GB/T 17851).
