标准范围

ISO 10678:2010规定了通过使用人工紫外线（UV）辐射降解水溶液中的染料分子亚甲基蓝（MB）来测定表面光催化活性的方法，并描述了光活性表面在紫外线辐射下降解溶解有机分子的能力。规定的试验方法也适用于评估各涂层覆盖表面的特定光催化自清洁活性。该方法不适用于在可见光照明下表征表面的光活性，涉及直接污染、气体分子降解和表面抗菌光活性的测定。

ISO 10678:2010 specifies a method for the determination of the photocatalytic activity of surfaces by degradation of the dye molecule methylene blue (MB) in aqueous solution using artificial ultraviolet (UV) radiation, and characterizes the ability of photoactive surfaces to degrade dissolved organic molecules on ultraviolet radiation.The test method specified is also applicable to evaluation of the specific photocatalytic self-cleaning activity of surfaces covered with respective coatings.This method is not applicable to characterizing the photoactivity of surfaces on visible illumination, regarding direct soiling, degradation of gaseous molecules and the determination of antimicrobial photoactivity of surfaces.
