Abstract: Disinfection of surfaces in medical facilities is an important element in the control of hospital infections, including these caused by bacteria, viruses and spores. Disinfecting agents need to exhibit specific characteristics, namely potential killing activity towards test bacteria which was determined experimentally in the laboratory. The methods in which a suspension of test bacteria is subject to the given agent are most often applied. However, the suspension methods do not fully imitate the conditions present in reality. Thus, in order to determine the concentrations of chemical disinfecting agents, carrier methods are applied. The new European standard i.e. EN 16615 Chemical disinfectants and antiseptics – Quantitative test method for the evaluation of bactericidal and yeasticidal activity on non-porous surfaces with mechanical action employing wipes in the medical area (4-field test) – Test method and requirements (phase 2, step 2), is a completely new standard for testing chemical surface disinfecting agents. It allows not only to assess the reduction in the number of test bacteria on the carrier, but also to examine possible interactions between the disinfecting agent and the material of which tissues and cloths are made. Additionally, it enables the evaluation of possible transfer of bacteria to adjucent areas via wiping.
