ASTM D 5767-95-2004 "Instrumental method for determining the distinctness of image Gloss of coating surface", which stipulates the standard method for using instruments to determine the distinctness of image Gloss of coating surface. The standard clarifies the technical parameters and calibrating requirements of the instrument, standardizes the preparation and measurement process of the sample, and uses the instrument to accurately quantify the clear reflection degree of the coating surface on the image by setting a specific Light source and observation angle. Provide a unified technical basis and testing criteria for scientifically evaluating the distinctness of image Gloss and controlling the coating Appearance mass.
