Assessment of Antibacterial Activity on Carpets:

It is comprised of three parts:
Part One: A qualitative antibacterial assessment.

Part two: A quantitative antibacterial assessment.

Part three: A quantitative antifungal assessment.

Test carpets are inoculated with test organisms. The number of test organisms present in the sample is determined at the time of inoculation by plate count method. After incubation, the bacteria are separated from the carpet material by shaking in known amounts of liquid. The number of bacteria in this liquid is determined by plate count method. This number is compared with the number of bacteria at 0 hour to calculate the percent reduction by the sample.

Sample Size: - Cut a circular disc from the test carpet with a steel die. The diameter of disc should be approximately 48mm

Turn around Time : 5 to 7 days for commonly used bacterial organisms, 3 to 4 weeks for fungus.
