Application Summary AI generated
GB/T 1182-2018 defines the rules for indicating geometrical tolerances (form, orientation, location, and run-out) on technical drawings, replacing coordinate tolerancing with symbolic annotations. It is applied in mechanical engineering, manufacturing, and quality inspection to specify permissible deviations in part geometry, ensuring interchangeability and functional assembly. This standard is essential for engineers and procurement professionals when communicating design requirements for machined components, automotive parts, and precision instruments.
