專家解讀視頻
This standard is included in DIN Handbook 175. Gives a method for estimating the loss of absorptive power of anodic oxidation coatings with a sealing treatment, by dye absorption after acid pretreatment. Suitable as a production control method and applies to anodic oxidation coatings which may be subjected to the weather or aggressive environments, or where resistance to staining is important.
