Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for antialgal activity of semiconducting photocatalytic materials
| Published By | Publication Date | Number of Pages |
| BSI | 2016 | 24 |
This International Standard specifies a test method for evaluating anti-algal activities in outdoor structures, specifically flat photocatalytic materials (for example, window panes and water tank glasses, films, guardrails, etc.) under irradiation of ultraviolet light. It does not include powder, granular or porous photocatalytic materials.
