ActiveAnodizing of aluminium and its alloys - Measurement of specular reflectance and specular gloss at angles of 20°,45°,60°or 85°
铝及铝合金阳极氧化 阳极氧化膜镜面反射率和镜面光泽度的测定 20°、45°、60°、85°角度方向
Application Summary AI generated
This standard specifies methods for measuring the specular reflectance and gloss of anodic oxide coatings on aluminium and its alloys at defined angles (20°, 45°, 60°, or 85°). It is applied in the manufacturing and quality control of anodized aluminium products, such as architectural panels, automotive trim, and consumer electronics, to ensure consistent optical appearance and surface finish. The standard is used by testing laboratories and production facilities to evaluate coating uniformity and meet customer specifications for gloss levels.
