NS EN 14204 : 2012

Defines a test method and the minimum requirements for mycobactericidal activity of chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation when diluted with hard water or - in the case of ready-to-use-products - with water. Products can only be tested at a concentration of 80% or less, as some dilution is always produced by adding the test organisms and interfering substance.
