GB/T 38761-2020 Geometrical product specifications (GPS)—Characteristics and conditions—Definitions

Scope: This International Standard defines general terms for geometric specifications, features and conditions. These definitions are based on the concepts in GB/T 24637.1 and GB/T 38760, and the mathematical description in Appendix B of GB/T 24637.1-2020. This standard is not only applicable to the field of industrial applications, but also can be used as a "road map" for understanding and planning geometric feature requirements, so that industry and software manufacturers can be unified in standardization. This standard defines the basic types of geometric features and conditions, these descriptions apply to the following situations: --- a workpiece; --- an assembly; --- a batch of workpieces; --- a batch of assemblies. These definitions are based on the concept and duality principle of the operation set in GB/T 24637.1 and GB/T 24637.2, and by
