适用范围：This International Standard specifies methods of assessing the quality of sealed anodic oxidation coatings onaluminium and its alloys by measurement of the loss of mass after immersion in phosphoric acid/chromic acidsolution.This International Standard consists of the following two methods.? Method 1: assessment of quality of sealed anodic oxidation coatings by measurement of the loss of massafter 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 massafter 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 whereresistance to staining is important.Method 2 is applicable to anodic oxidation coatings intended for architectural purposes. For less severeapplications, 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.
