ISO 2931:2010规定了通过测量导纳评估铝及其合金上密封阳极氧化涂层质量的方法。 该方法适用于在水介质中密封的阳极氧化涂层。 该方法适用于生产控制测试和供应商与客户之间达成协议的验收测试。 只要有足够的面积（直径约20 mm的圆）且膜厚度大于3μm，任何类型的阳极氧化组件都可以通过所述方法进行测试。

ISO 2931:2010 specifies a method for assessing the quality of sealed anodic oxidation coatings on aluminium and its alloys by measurement of the admittance. The method is applicable to anodic oxidation coatings sealed in an aqueous medium. The method is suitable for use as a production-control test and as an acceptance test where there is agreement between the supplier and the customer. Any type of anodized component can be tested by the method described, provided that there is a sufficient area (a circle of diameter about 20 mm ) and that the film thickness is greater than 3 μm.
