Organization: ISO
Publication Date: 15 July 2009
Status: active
Page Count: 14
ICS Code (Advanced ceramics): 81.060.30
scope:

This International Standard deals with fine ceramics.

This International Standard specifies a test method for the determination of the self-cleaning performance of materials that contain a photocatalyst or have photocatalytic films on the surface, and which are usually made from semiconducting metal oxides such as titanium dioxide.

This method is used to measure the water contact angle under illumination with ultraviolet light, which is one of the indices influencing the self-cleaning performance of photocatalytic materials.

This International Standard does not include water-permeable substrates, rough surfaces which do not have exposed water droplets, highly hydrophobic, powder or granular materials, or visible light-sensitive photocatalysts.
