ActiveAnodizing of aluminium and its alloys - Visual determination of image clarity of anodic oxidation coatings - Chart scale method
铝及铝合金阳极氧化 阳极氧化膜影像清晰度的测定 条标法
Application Summary AI generated
This standard specifies a method for visually assessing the image clarity of anodic oxidation coatings on aluminium and its alloys using a chart scale. It is applied in manufacturing and quality control settings to evaluate the surface quality of anodized aluminium products, such as architectural panels, automotive trim, and consumer electronics. The test involves comparing the reflection of a standardized chart on the coated surface to determine the coating's ability to retain a sharp image.
