BS ISO 22197-2:2019 Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for air-purification performance of semiconducting photocatalytic materials - Removal of acetaldehyde
What is ISO 22197 ‑ 2 - Fine ceramics about ?
ISO 22197 ‑ 2 is part two 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 acetaldehyde.
ISO 22197 ‑ 2 specifies a test method for the determination of the air-purification performance of materials that contain a photocatalyst or have photocatalytic films, 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).
