AbolishedTest Methods for anodic oxidation coatings of aluminium and aluminium alloys - Part 6:Determination of color differences and appearance of colored anodic oxide films by viewing method
铝及铝合金阳极氧化膜检测方法 第6部分：目视观察法检验着色阳极氧化膜色差和外观质量
Application Summary AI generated
This standard specifies a visual inspection method for evaluating color differences and surface appearance defects on colored anodic oxide coatings applied to aluminum and aluminum alloys. It is primarily used in manufacturing quality control and acceptance testing for architectural profiles, automotive trim, consumer electronics casings, and other decorative aluminum products where consistent color and finish are critical. The method relies on trained inspectors comparing samples under controlled lighting conditions to ensure the coated surfaces meet specified aesthetic and uniformity requirements.
