Anodizing of aluminium and its alloys. Determination of thickness of anodic oxidation coatings. Non-destructive measurement by split-beam microscope
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 10Â ÎĽm, or above 5Â ÎĽm 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 separated, i.e. not in the case of opaque or dark-coloured coatings.
NOTE Problems can arise as a result of the roughness of the surface.
