Application Summary AI generated
GB/T 6321-2004 specifies the design, technical requirements, and testing methods for spring-optical measuring heads, which are precision instruments that combine a spring mechanism with optical magnification for high-accuracy dimensional measurements. It is applied in mechanical manufacturing and quality control laboratories for measuring small displacements, such as checking the geometric tolerances of machined parts, gauges, and precision components. The standard ensures consistency and reliability in metrology settings where non-contact or low-force measurements are critical.
