ISO 2128:1976 Anodizing of aluminium and its alloys; Determination of thickness of anodic oxide coatings; Non-destructive measurement by split-beam microscope
The measurements apply in the most common cases to anodic oxide coatings having a thickness more than 10 m, or from 5 m with an even surface. The use of the measurement is limited by two factors: an opaque coating and an uneven surface.
