Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for self-cleaning performance of semiconducting photocatalytic materials under indoor lighting environment. Measurement of water contact angle Ingestion-build-44616 declaration1 Scope This document specifies a test method for the determination of the self cleaning performance of sheet form materials that contain an indoor light active photocatalyst or have indoor light active photocatalytic films on the surface, under indoor lighting environment. This method is used to measure the change of water contact angle under indoor lighting environment, which is one of the indices reflecting the self cleaning performance of
