Anodizing of aluminium and its alloys -- Determination of thickness of anodic oxidation coatings -- Non-destructive measurement by split-beam microscope
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
ISO 2128:2010 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 μm, or above 5 μm 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.
