Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for air-purification performance of semiconducting photocatalytic materials - Removal of methyl mercaptan Ingestion-build-79769 BS EN IEC 60193 applicable1 Scope This part of ISO 22197 specifies a test method for the determination of the air purification performance of materials that contain a photocatalyst or have photocatalytic films on the surface, usually made from semiconducting metal oxides, such as titanium dioxide or other ceramic materials, by continuous exposure of a test piece to the model air pollutant under illumination with ultraviolet light (UV A). This part of ISO 22197 is intended for
