《GB/T 8753.3-2005铝及铝合金阳极氧化 氧化膜封孔质量的评定方法 第3部分:导纳法》由TC243（全国有色金属标准化技术委员会）归口，TC243SC1（全国有色金属标准化技术委员会轻金属分会）执行，主管部门为中国有色金属工业协会
本部分规定了导纳法测定铝及铝合金阳极氧化膜封孔质量的方法。本部分适用于在水溶液中封孔的，膜厚大于3 mm的铝及铝合金阳极氧化膜封孔质量的快速无损测定。本部分规定的方法既适用于热封孔的阳极氧化膜，也适用于冷封孔的阳极氧化膜。本部分可作为产品质量控制方法，也可作为供需双方商定的验收方法。

Scope

This part specifies the method for determining the sealing quality of aluminum and aluminum alloy anodized film by admittance method. This part is applicable to the rapid and non-destructive determination of the quality of aluminum and aluminum alloy anodic oxidation films whose film thickness is greater than 3 mm and which are sealed in aqueous solution. The methods specified in this section are applicable to both heat-sealed anodized films and cold-sealed anodized films. This part can be used as a product quality control method, or as an acceptance method agreed upon by the supplier and the purchaser.
