BS ISO 22196:2011

Measurement of antibacterial activity on plastics and other non-porous surfaces

The ISO 22196:2011 standard outlines a test method to evaluate the antibacterial effectiveness of plastics and other non-porous surfaces. ISO 22196:20211 applies to the testing of products that incorporate an antibacterial agent to suppress the growth of bacteria on the product surface. The test method is based on JIS Z 2801.

Test Description

  • Bacteria (Staphylococcus aureus or Escherichia coli) are inoculated onto the test and control surfaces. Other bacteria strains can also be used if required.
  • The samples are incubated for a set duration, after any viable bacteria present are recovered and enumerated.
  • The ability of the antibacterial agent to inhibit the growth of bacteria on the surface of materials treated is calculated according to the criteria in the standard.

Sample submission
We will provide you with a quote based on the number of samples and number of bacteria strains you wish to test. Flat, square (50 mm x 50 mm) samples no more than 10 mm thick are preferred, but other sizes and shapes may be used.

Turnaround Time
We aim to report your results within 4 weeks of receiving samples.

Third Party Validation
On passing this test, the product can be labelled as having been tested by airmid healthgroup to BS ISO 22196:2011 in support of any claim relating to the test and data received.

“The quality of the third party data we received from airmid healthgroup helped us showcase our innovative strategy of licensing this novel technology at a prestigious international scientific event, the European Innovation Convention. Ultimately this will allow us add value and differentiate our customer offerings through a focus on health and indoor air quality.”
