GB/T 33523.700-2025

This standard specifies the calibration, adjustment, and verification procedures for areal topography measuring instruments, such as optical profilers and stylus-based systems. It is applied in precision manufacturing and quality control contexts to ensure the accuracy and traceability of surface texture measurements on components like machined parts, optics, and semiconductors. The standard is essential for laboratories and production facilities that require consistent and reliable areal surface roughness data according to the Geometrical Product Specifications (GPS) framework.
