适用范围：This International Standard specifies a gravimetric method for determining the mass per unit area (surfacedensity) of anodic oxidation coatings on aluminium and its alloys.The method is applicable to all oxidation coatings formed by anodizing aluminium and its alloys, either cast orwrought, and is suitable for most aluminium alloys, except those in which the copper content is greater than6 %.NOTE 1 A high content of copper in the alloy can lead to increased dissolution of the basis aluminium.NOTE 2 If the thickness is known with sufficient precision (for example, using the method specified in ISO 2128),determination of the mass per unit area (surface density) of the coatings will enable its apparent density to be calculated.Conversely, if the conditions of application of the coating and its density are known, the determination of its mass per unitarea (surface density) can permit calculation of the average mass and an approximate evaluation of the thickness (see theNote in Clause 6).
