This International Standard specifies methods of assessing the quality of sealed anodic oxidation coatings on aluminium and its alloys by measurement of the loss of mass after immersion in phosphoric acid/chromic acid solution. This standard consists of the following two methods. Method 1: Assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass after immersion in phosphoric acid/chromic acid solution without prior acid treatment. Method 2: Assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass after immersion in phosphoric acid/chromic acid 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 architectural purposes. For less serve application, Method 1 may be more suitable. The methods are not applicable to: 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 a treatment to render them hydrophobic. The methods are destructive and can serve as a reference methods in case of doubt or dispute regarding the results of the test for loss of absorptive power (ISO 2143: 1), or the measurement of admittance (ISO 2931: 2) To be published. (Revision of ISO 2143:1981) 2)To be published. (Revision of ISO 2931:1983).
