标准摘要
[中文适用范围]： 本国际标准规定了一种使用分光显微镜无损测定铝及其合金上阳极氧化涂层厚度的方法。该方法适用于大多数工业情况，即厚度大于 10 µm 的阳极氧化涂层，或表面光滑时厚度大于 5 µm 的涂层。使用所规定方法的限制在于需要 Clause 3 中描述的两条发光线可见且明显分离，即不适用于不透明或深色涂层。注：表面粗糙度可能会导致问题。 [外文原描述]： ISO 2128:2010 specifies a non-destructive method for determining the thickness of anodic oxidation coatings on aluminium and its alloys using a split-beam microscope. The method is applicable, in most industrial cases, to anodic oxidation coatings above 10 μm, or above 5 μm when the surface is smooth. The use of the method specified is limited by the need for the two luminous lines described in Clause 3 to be visible and distinctly separated, i.e. not in the case of opaque or dark-coloured coatings.
