DIN EN 16437:2014-07

DIN EN 16437 specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectants 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. This European Standard applies to products that are used in the veterinary area on porous surfaces without mechanical action, that is in the breeding, husbandry, production, transport and disposal of all animals except when in the food chain following death and entry to the processing industry. The laboratory test takes into account practical conditions of application of the product including pre-drying test organisms and interfering substances on a surface, contact time and temperature that are conditions which may influence the action of the product in practical situations. The conditions are intended to cover general purposes and to allow reference between laboratories and product types. Each utilization concentration of the chemical disinfectant or antiseptic, found by this test corresponds to the chosen experimental conditions. However, for some applications, the instructions of use of a product can differ and therefore additional test conditions shall be used. The European Standard has been prepared by CEN/TC 216 "Chemical disinfectants and antiseptics", the secretariat of which is held by AFNOR (France). The collaboration of DIN for the scope of CEN/TC 216 is performed through the national mirror committee, Working Committee NA 057-02-03 AA "Desinfektionsmittel Tierhaltung/Lebensmittelbereich" ("Disinfectants for veterinary use and food area") of NAL.
