METHODS OF TEST FOR ANODIC OXIDATION COATINGS ON ALUMINIUM AND ITS ALLOYS - ASSESSMENT OF SEALING QUALITY BY MEASUREMENT OF THE LOSS OF MASS AFTER IMMERSION IN PHOSPHORIC CHROMIC ACID SOLUTION
出版：British Standards Institution
专家解读视频
Specifies a method for assessing the quality of sealed anodic coatings on aluminium and its alloys. The method depends on the measurement of the loss of mass after immersion in phosphoric-chromic acid solution. The method applies to anodic coatings meant for exposure to weather, where resistance to staining is important and for protective purposes in corrosive media. Does not apply to: anodic coatings that have been sealed only in dichromate solutions; hard-type anodic coatings which normally are not sealed; and anodic coatings that have undergone a treatment to render them hydrophobic.
