Samples were tested to ISO 22196:2011. This method is a quantitative test designed to assess the performance of antibacterial properties on hard, non-porous surfaces.
Submitted samples are challenged against stock cultures of S.aureus,E.coli, Campylobacter, Legionella and Ps.aeruginosa purchased from ATCC.
Samples are inoculated using a known amount of the above cultures and incubated for 24 hours at 37°C according to ISO 22196:2011. TVC (Total Viable Count) of bacteria are then recorded and the percentage of reduction is calculated.
All testing is carried out independently at Industrial Microbiological Services Ltd.
