GB/T 24634-2009

This standard defines the general concepts and requirements for measuring equipment used in geometrical product specifications (GPS), establishing a framework for the selection, calibration, and verification of such devices. It is applied in manufacturing and quality control environments to ensure consistent and accurate dimensional measurements of mechanical parts, particularly in industries like automotive, aerospace, and precision engineering. The standard serves as a foundational reference for metrology laboratories and production facilities to maintain traceability and interoperability of GPS measurement results.
