GB/T 6060.3-2008 《Surface roughness comparison specimen － Part 3：Spark-eroded，shot-blasted，grit-blasted，lapped，filed and polished surface》 Related products

GB/T 6060.3-2008 standard specifies the terms, definitions and evaluation methods for comparison samples of machined surface roughness such as spark, shot, sand blasting, grinding, filing and polishing. The standard applies to the surface roughness evaluation of these processing methods, and the surface roughness parameter value is determined by comparing the tactile and visual contrast between the sample and the measured surface. The standard also describes the manufacturing method, surface characteristics and marking Encasement of these samples in detail, which provides a reference for the asperity evaluation of machined surfaces.
