GB/T 12967.6-2008 《Test 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》 Related products

GB/T 1 2967.6 - 2008 Focus on the detection of anodic oxide coatings for aluminum and aluminum alloys. This part specializes in the method of inspection chromadizing anodic oxide coatings color difference and Appearance mass by visual observation. It clarifies the scope of application of the detection, and details how to visually judge the Color difference, Surface Smoothness, and presence of defects of oxide films according to standard samples and specified conditions. It provides an intuitive and practical judgment basis for the mass evaluation of aluminum and aluminum alloy products after anodic oxidation treatment to ensure product Appearance mass.
