The ASTM D4417-19 standard provides a method for on-site measurement of sand blasting cleaned steel surface profiles. The standard is suitable for evaluating steel surface roughness to ensure adhesion and durability of coatings. The standard details the use of different types of measurement tools, such as Comparison Blocks, Stylus Roughness Gauge, and Surface Profile Gauge, to determine the asperity grade of steel surfaces after sand blasting cleaning. Through these methods, it is possible to effectively evaluate the asperity of steel surfaces and ensure the adhesion and durability of coatings.
