DS/ISO 2931:1988 Anodizing of aluminium and its alloys. Assessment of quality of sealed anodic oxide coatings by measurement of admittance or impedance
This International Standard specifies a method for assessing the quality of sealed anodic oxide coatings on aluminium and its alloys, by measurement of the admittance or the impedance.
The method is suitable for use as a production control test. It is also suitable for use as an acceptance test when there is agreement between the manufacturer and the purchaser.
