GB/T 33523.6-2017

This standard provides a classification system for areal surface texture measurement methods, categorizing them based on principles such as optical, mechanical, or scanning probe techniques. It is applied in manufacturing and quality control contexts where engineers and metrologists must select appropriate instruments (e.g., confocal microscopes, stylus profilers) for evaluating surface roughness, waviness, and form on machined parts. The classification aids in standardizing measurement procedures across industries like automotive, aerospace, and precision engineering to ensure consistent and comparable surface texture data.
