| Resumen: | This document specifies two methods to assess the quality of sealed anodic oxidation coatings on aluminium and its alloys: - Method 1 which assesses the quality of sealed anodic oxidation coatings by measuring the loss of mass after immersion in a phosphoric acid based solution without prior acid treatment; - Method 2 which assesses the quality of sealed anodic oxidation coatings by measuring the loss of mass after immersion in a phosphoric acid based solution with prior acid treatment. Method 1 is applicable to anodic oxidation coatings intended for decorative or protective purposes or where resistance to staining is important. Method 2 is applicable to anodic oxidation coatings intended for outdoor architectural purposes. For less severe applications, Method 1 can be more suitable. The methods are not applicable to the following: - hard-type anodic oxidation coatings which normally are not sealed; - anodic oxidation coatings that have been sealed only in dichromate solutions; - anodic oxidation coatings produced in chromic acid solutions; - anodic oxidation coatings that have undergone treatment to render them hydrophobic. |
