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, usually made from semiconducting metaloxides, such as titanium dioxide or other ceramic materials, by continuous exposure of a test piece to themodel air pollutant under illumination with ultraviolet light (UV-A). This part of ISO 22197 is intended for usewith different kinds of materials, such as construction materials in flat sheet, board or plate shape, that are thebasic forms of materials for various applications. This part of ISO 22197 also applies to structured filtermaterials including honeycomb-form, woven and non-woven fabrics, and to plastic or paper materials if theycontain ceramic microcrystals and composites. This part of ISO 22197 does not apply to powder or granularphotocatalytic 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 acetaldehyde.
