The standard test for evaluating the performance of antimicrobial surfaces is the JIS Z 2801:2000 or ISO 22196 method, which can be summarised as follows...

Each test sample is inoculated with a suspension of the test organism (for example, MRSA). The inoculum is held in contact with the test sample using a sterile polyethylene film. All test samples are inoculated in triplicate, with an additional three replicates of the control. The bacterial population on three control replicates is evaluated immediately following inoculation. This is assumed to be the initial population on all test samples (i.e. the population at zero hours). The remaining samples are incubated for the test period (typically 24 hours) at 35°C, at which time the bacterial population is evaluated.

The standard organisms used in the JIS/ISO method are MRSA and E. Coli, however we are also able to provide testing against a range of other organisms, including salmonella, pseudomonas, klebsiella, legionella, aspergillus, penicillium and candida.
