ISO 17094:2014
Photocatalysts are composed of semi-conducting metal oxides such as titanium dioxide and zinc oxide. The ISO 17094:2014 standard is designed to determine the anti-bacterial activity of materials containing an indoor-light active photocatalyst or have indoor-light active photocatalytic films on their surface, by measuring the survial of bacteria after illumination with indoor light. ISO 17094:2014, though intended for use with ceramics, can also be used with other photocatalytic-treated materials such as textiles, glass and plastics.
Description of Test
- Bacteria (Escherichia coli and Staphylococcus aureus) are inoculated onto the test and control materials.
- After a period of artificial light exposure, viable bacteria are extracted from the test and control materials and enumerated on a nutrient agar medium.
- The efficacy of the anti-bacterial treatment in response to light is calculated by comparing the test and the control materials according to criteria outlined in the standard.
- The antibacterial effect is also assessed in the dark and incorporated into the calculations.
- Other bacteria or fungal species can be used upon request.
