ISO 3210:2010 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.
ISO 3210:2010 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 severe applications, Method 1 may 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 a treatment to render them hydrophobic.
