Anodizing of aluminium and its alloys; Assessment of sealing quality by measurement of the loss of mass after immersion in acid solution
Описание (англ.):
Two methods are specified for anodic coatings intended for exposure to the weather, or for protective purposes in corrosive media, or where resistance to staining is important. The methods are not applicable to unsealed, hard and other special coatings. The acid solution is sodium acetate/acetic acid solution or acidified sodium sulphite solution.
