This Part of this European Standard specifies a method of estimating the loss of absorptive power of anodic oxidation coatings that have undergone a sealing treatment, by dye absorption after acid pretreatment.<\/p>\n

The method is suitable for use as a production control method and is applicable to anodic oxidation coatings which may be subjected to weathering or aggressive environments or where resistance to staining is important.<\/p>\n

The method is not applicable to those coatings:<\/p>\n

    \n
  1. \n

    formed on alloys containing more than 2 % copper or 4 % silicon;<\/p>\n<\/li>\n

  2. \n

    sealed by the dichromate process;<\/p>\n<\/li>\n

  3. \n

    that have been given supplementary processing, for example oiling, waxing or lacquering;<\/p>\n<\/li>\n

  4. \n

    that are coloured in deep shades;<\/p>\n<\/li>\n

  5. \n

    that are less than 3 \u00b5m thick.<\/p>\n<\/li>\n<\/ol>\n

    The method is less appropriate where nickel or cobalt salts, or organic additives, have been added to the sealing bath.<\/p>\n
