Anodizing of aluminium and its alloys. Determination of thickness of anodic oxidation coatings. Non-destructive measurement by split-beam microscope Ingestion-build-181247 It also provides a framework1 Scope This International Standard specifies a non destructive method for determining the thickness of anodic oxidation coatings on aluminium and its alloys using a split beam microscope. The method is applicable, in most industrial cases, to anodic oxidation coatings above 10 m, or above 5 m when the surface is smooth. The use of the method specified is limited by the need for the two luminous lines described in Clause 3 to be visible and distinctly
