Anodizing of aluminium and its alloys - Assessment of quality of sealed anodic oxidation coatings by measurement of admittance (ISO 2931:2017); German version EN ISO 2931:2018
Anodisieren von Aluminium und Aluminiumlegierungen - Prüfung der Qualität von verdichteten, anodisch erzeugten Oxidschichten durch Messung des Scheinleitwertes (ISO 2931:2017); Deutsche Fassung EN ISO 2931:2018
Overview
The test described in this document is intended to give a quick, non-destructive assessment of the quality of sealed anodic oxidation coatings and is very suitable for routine production control. It is carried out following sealing and before any other supplementary process is undertaken, for example, oiling, waxing or lacquering. This International/European Standard has been prepared under the direction of ISO/TC 79/SC 2 "Organic and anodic oxidation coatings on aluminum" (secretariat: JISC, Japan) in parallel with CEN/TC 132 "Aluminum and aluminum alloys" (secretariat: AFNOR, France). The responsible German standardization committee is DIN Working Committee NA 066-01-09 AA "Anodisch oxidiertes Aluminium" ("Aluminium anodisation") at FNNE.
