ISO 27447:2009

 

Photocatalysts are composed of semi-conducting metal oxides such as titanium dioxide and zinc oxide. The ISO 27447:2009 standard is designed to determine the anti-bacterial activity of materials containing the photocatalyst or have photocatalytic films on their surface, by enumerating bacteria after exposure to ultraviolet (UV) light. ISO 27447:2009, 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 UV 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 UV 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.
