| Resumen: | This document specifies a method for assessing the quality of sealed anodic oxidation coatings on aluminium and its alloys by measurement of the admittance. The method is applicable to anodic oxidation coatings sealed in an aqueous medium. The method is suitable for use as a productions control test and as acceptance test where there is agreement between the supplier and the customer. Any type of anodized component may be tested by the method described, provided that there is sufficient area (a circle of about 20 mm diameter) and that the film thickness is greater than 3 µm. |
