Fine ceramics (advanced ceramics, advanced technical ceramics). Ultraviolet light source for testing semiconducting photocatalytic materials Ingestion-build-225643 and where an estimate is1 Scope This International Standard describes an ultraviolet (UV) light source and specifies a method of measuring the radiation intensity which is used in testing the performance of semiconducting photocatalytic materials in a laboratory.
