Application Summary AI generated
This standard establishes the foundational concepts, principles, and rules for Geometrical Product Specifications (GPS), providing a unified framework for defining and interpreting tolerances of size, form, orientation, and location. It is applied across mechanical engineering and manufacturing industries to ensure consistent communication of design intent between design, production, and quality inspection teams. The standard is critical for any context involving technical drawings, CAD models, or measurement protocols where geometric tolerancing is required.
