标准范围
This part of ISO 22197 specifies a test method for the determination of the air-purification performance ofmaterials that contain a photocatalyst or have photocatalytic films on the surface, usually made fromsemiconducting metal oxides, such as titanium dioxide or other ceramic materials, by continuous exposure ofa test piece to the model air pollutant under illumination with ultraviolet light (UV-A). This part of ISO 22197 isintended for use with different kinds of materials, such as construction materials in flat sheet, board or plateshape, that are the basic forms of materials for various applications. This part of ISO 22197 also applies tostructured filter materials including honeycomb-form, woven and non-woven fabrics, and to plastic or papermaterials if they contain ceramic microcrystals and composites. This part of ISO 22197 does not apply topowder or granular photocatalytic materials.This test method is usually applicable to photocatalytic materials produced for air purification. This method isnot suitable for the determination of other performance attributes of photocatalytic materials,i.e. decomposition of water contaminants, self-cleaning, antifogging and antibacterial actions. It concerns theremoval of toluene.
