Fine ceramics (advanced ceramics, advanced technical ceramics) -- Determination of photocatalytic activity of surfaces in an aqueous medium by degradation of methylene blue
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
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.
