标准范围

ISO 3210:2010规定了通过测量浸泡在磷酸/铬酸溶液中后的质量损失来评估铝及其合金上的密封阳极氧化涂层质量的方法。ISO 3210:2010由以下两种方法组成。方法1:通过测量在没有预先酸处理的情况下浸入磷酸/铬酸溶液中后的质量损失来评估密封阳极氧化涂层的质量。方法2:通过测量浸入磷酸/铬酸溶液中并具有先前酸处理后的质量损失来评估密封阳极氧化涂层的质量。方法1适用于用于装饰或保护目的的阳极氧化涂层或其中耐沾污性是重要的。方法2适用于用于建筑目的的阳极氧化涂层。对于不太严重的应用，方法1可能更合适。这些方法不适用于以下情况:通常不密封的硬质阳极氧化涂层；仅密封在重铬酸盐溶液中的阳极氧化涂层；在铬酸溶液中产生的阳极氧化涂层；经过疏水处理的阳极氧化涂层。

ISO 3210:2010 specifies methods of assessing the quality of sealed anodic oxidation coatings on aluminium and its alloys by measurement of the loss of mass after immersion in phosphoric acid/chromic acid solution.ISO 3210:2010 consists of the following two methods.

• Method 1: assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass after immersion in phosphoric acid/chromic acid solution, without prior acid treatment.
• Method 2: assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass after immersion in phosphoric acid/chromic acid solution with prior acid treatment.

Method 1 is applicable to anodic oxidation coatings intended for decorative or protective purposes or where resistance to staining is important.Method 2 is applicable to anodic oxidation coatings intended for architectural purposes. For less severe applications, Method 1 may be more suitable.The methods are not applicable to the following:

• hard-type anodic oxidation coatings which normally are not sealed;
• anodic oxidation coatings that have been sealed only in dichromate solutions;
• anodic oxidation coatings produced in chromic acid solutions;
• anodic oxidation coatings that have undergone a treatment to render them hydrophobic.
