NF ISO 10678, B44-104 (12/2024)

ISO 10678:2010 specifies a method for determining the photocatalytic activity of surfaces by degradation of the methylene blue (MB) dye molecule in an aqueous solution using artificial ultraviolet (UV) irradiation and characterizes the capacity of photoactive surfaces to degrade dissolved organic molecules under ultraviolet radiation. The specified test method is also applicable to the evaluation of the specific self-cleaning activity by photocatalysis of surfaces provided with respective coatings. This method is not applicable to the characterization of the photoactivity of surfaces exposed to visible light illumination with regard to dirt, the degradation of gas molecules and the determination of the antimicrobial photoactivity of surfaces.
