Test Standards

• ISO 22196
  ISO 22196 specifies the method of evaluating the antibacterial activity of antibacterial-treated plastics, and other non-porous surfaces.

  Recommended bacteria used for the purpose of this evaluation includes, but not limit to, ATCC 6538™ Staphylococcus aureus and ATCC 8739™ Escherichia coli. These strains are also widely-accepted industry standards used in the testing of bacterial resistance in non-plastic consumer products such as textiles, food-packaging materials, etc.

• ISO 21702
  ISO 21702 refers to testing of measurement of Antiviral Activity on plastics and other non-porous surfaces. In many countries, the SARS-CoV-2 virus is categorized at Biohazard Level-3 and above, available for public commercial testing until recently. Many non-medical, commercial claims of efficacy against coronavirus, are either tested with pre-2019 coronavirus strains, animal coronavirus, or the surrogate Murine Hepatitis virus to demonstrate the antiviral efficacy of this technology against a member of the coronavirus family.

Window film products are recommended to be tested with Human SARS-CoV-2 variants.
