GB/T 24637.4-2020 Geometrical product specifications (GPS)—General concepts—Part 4:Geometrical characteristics for quantifying GPS deviations

Scope

This part of GB/T 24637 provides quantification rules for GPS deviations of individual GPS features.
This part is applicable to quantifying GPS deviations of geometrical features.
Note: GPS deviations can be local or global. A GPS feature defined by local GPS deviations is a parameter that converts the set of local deviations into a global feature through a quantification function (see Table 1).
