本文件规定了一种定性评估光催化表面活性的方法，即瑞苏林（Rz）油墨试验，其分类如下、在试验适用范围内或以上。然后，该方法允许对试验适用范围内的光催化表面的活性进行后续半定量评估。在所有情况下，都会使用人工紫外线（UV）辐射。 规定的试验方法适用于所有平坦、光滑的光催化表面，这些表面不是大孔的，例如: 商用光催化玻璃、油漆、瓷砖和遮阳篷材料。该方法不适用于评估光催化表面的可见光活性，也不适用于评估其影响空气净化、水净化、自清洁或消毒的能力，尽管已经报道了一些相关的相关性。

This document specifies a method, the Resazurin (Rz) ink test, for the qualitative assessment of the activity of a photocatalytic surface, and its classification as below, within, or above the applicable range of the test. The method then allows for the subsequent semiquantitative evaluation of the activities of photocatalytic surfaces that are within the applicable range of the test. In all cases, artificial ultraviolet (UV) radiation is used. The test method specified is appropriate for use with all flat, smooth, photocatalytic surfaces, which are not macroporous, examples of which include: commercial photocatalytic glass, paint, tiles and awning materials. The method is not applicable to assessing the visible-light activity of photocatalytic surfaces, nor their ability to effect: air purification, water purification, self-cleaning or disinfection, although some relevant correlations have been reported^[4][5].
