BS ISO 21066:2018规定了一种方法，即瑞苏林（Rz）油墨试验，用于定性评估光催化表面的活性，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。交叉引用:ISO 10677ISO 20507:2014ISO 22197-1:2016ASTM E691-13购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 21066:2018 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.Cross References:ISO 10677ISO 20507:2014ISO 22197-1:2016ASTM E691 - 13All current amendments available at time of purchase are included with the purchase of this document.
