《GB/T 8753.2-2005铝及铝合金阳极氧化 氧化膜封孔质量的评定方法 第2部分:硝酸预浸的磷铬酸法》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
本部分规定了铝及铝合金阳极氧化膜经硝酸预浸后，于磷-铬酸溶液中浸蚀，按质量损失评定其封孔质量的方法。本部分既适用于热封孔的阳极氧化膜，又适用于冷封孔的阳极氧化膜。本部分不适用于下列工艺处理的阳极氧化膜：a) 通常不进行封孔处理的硬质阳极氧化膜；b) 在重铬酸盐溶液中封孔处理过的阳极氧化膜；c) 在铬酸溶液中生产的阳极氧化膜；d) 经疏水处理的阳极氧化膜。

Scope

This part specifies the method for evaluating the sealing quality of aluminum and aluminum alloy oxide film after nitric acid pre-soaking and etching in phosphorus-chromic acid solution, according to the mass loss. This section applies to both heat-sealed anodized films and cold-sealed anodized films. This standard does not apply to anodized coatings treated by the following processes: a) hard anodized coatings that are not normally sealed; b) anodized coatings that have been sealed in a dichromate solution; Anodized film produced in acid solution; d) Hydrophobic treated anodized film.
