properties can significantly reduce contamination risks. The determination of the antibacterial activity ( microbicidy) of surfaces is described in the following norms: ISO 22196 and JIS Z 2801.JIS Z 2801:2000 Antimicrobial products- test for antimicrobial activity and efficacy The Japanese norm JIS Z 2801 was published in 2000 and published again in 2007 as the internationally valid norm ISO 22196. Therefore, ISO 22196 and JIS Z 2801 are identical. In the test, both a surface system coated with sporicide and an identical surface system without an antibacterial coating are charged with selected
