Aluminium and aluminium alloys - Anodizing - Part 3: Determination of thickness of anodic oxidation coatings; non-destructive measurement by split-beam-microscope; German version EN 12373-3:1998
The measurements apply in the most common cases to anodic oxide coatings having a thickness more than 10?or from 5?with an even surface. The use of the measurement is limited by two factors: an opaque coating and an uneven surface.
