GB/T 7220-2004 《Geometrical Product Specifications(GPS)--Surface texture:Profile method--Surfaceroughness--Terminology--Measurement of surface roughness parameters》 Related products
The GB/T 7220-2004 standard defines the terms of surface structure and its parameter Measuring method, which is applicable to the evaluation of surface roughness, surface ripple and original contour by contour method. The standard content includes detailed definitions of concepts such as contour transformation, trajectory contour, expected and unintended contour transformation. These terms and definitions provide a uniform reference for the accurate measurement of surface structure parameters, ensuring conformity and repeatability of the surface structure assessment process in the product geometric quantity technical specification (GPS).
