Anodizing of aluminium and its alloys - Measurement of specular reflectance and specular gloss at angles of 20°,45°,60°or 85°

GB/T 20503-2006 specifies methods for measuring the specular reflectance and specular gloss of anodic oxidation coatings on aluminium and aluminium alloys using four measurement angles: 20°, 45°, 60°, and 85°. It is applicable to the characterization of various oxidation coatings, ranging from high gloss to low gloss.
