Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for water purification performance of semiconducting photocatalytic materials by measurement of forming ability of active oxygen Ingestion-build-159183 The size designation system is

The size designation system is based on body and not on garment measurements

It is not particularly directed to the certification of reference materials (particularly chemical substances) and to calibrations where artefacts are compared using a scheme known as a “weighing design”

Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for water purification performance of semiconducting photocatalytic materials by measurement of forming ability of active oxygen Ingestion-build-159183 The size designation system is1 Scope This International Standard describes a test method covering photocatalytic materials formed on, or attached to, another material surface for the purpose of decomposing, and thus eliminating the pollutants in water, using photocatalytic performance. This test method is applicable to photocatalytic materials under UV irradiation, and not under visible light irradiation.
