| 1. |
Specimen name: HCG photocatalytic ceramic tile: light item (23W O•ZONELite™) |
| 2. |
Purpose of test: Antibacterial strength evaluation test |
| 3. |
Test method: Light irradiation film adhesion method: (light item) |
|
|
According to "Light Irradiation Film Adhesion Method of the Antibacterial Manufacturing Technical Cooperative Society," a bacterial solution prepared with 1/500 ordinary bouillon was dripped on the surface of a test strip, and this was adhered with film and stored while being irradiated with fluorescent light at 20-25 degress C (luminosity approx. 5500lx). The number of bacteria on the test strip was measured. |
