Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for air-purification performance of semiconducting photocatalytic materials - Removal of toluene
What is ISO 22197 ‑ 3 - Fine ceramics - Removal of toluene about ?
ISO 22197 ‑ 3 is part three of a multi-series of international standards on fine ceramics which covers a test method for air purification performance of semiconducting photocatalytic materials and removal of toluene.
ISO 22197 ‑ 3 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 irradiation with ultraviolet light (UV-A).
