Anodizing of aluminium and its alloys. Assessment of quality of sealed anodic oxidation coatings by measurement of admittance Ingestion-build-63436 BS EN 61672-1 is applicable1 Scope This document specifies a method for assessing the quality of sealed anodic oxidation coatings on aluminium and its alloys by measurement of the admittance. The method is applicable to anodic oxidation coatings sealed in an aqueous medium. NOTE 1 Results obtained from anodic oxidation coatings sealed by different methods, e. g. hydrothermal sealing and cold sealing, are not necessarily comparable. NOTE 2 Results obtained from anodic oxidation
