Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for complete decomposition performance of semiconducting photocatalytic materials under indoor lighting environment. Decomposition of acetaldehyde Ingestion-build-47786 a clean air delivery rate1 Scope This document specifies a test method for the determination of complete decomposition performance of indoor light active photocatalytic materials under an indoor lighting environment using acetaldehyde. In this document, photocatalytic materials are usually made from semiconducting metal oxides, such as titanium dioxide, tungsten trioxide or other ceramic materials, and they are treated in powder form. This document does not apply to film,
