DIN EN 16438:2014-07

DIN EN 16438 specifies a test method and the minimum requirements for fungicidal or yeasticidal activity of chemical disinfectant and antiseptic products that form a homogeneous physically stable preparation in hard water or - in the case of ready-to-use products - with water. This European Standard applies to products for use in the veterinary area that is in the breeding, husbandry, production and transport and disposal of all animals except when in the food chain after death and entry to the processing industry. EN 14885 specifies in detail the relationship of the various tests to one another and to "use recommendations". This 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 determined utilization concentration of the chemical disinfectant or antiseptic, found by this test corresponds to the chosen experimental conditions. However, for some applications, the recommendations 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") at the Standards Committee Food and Agricultural Products (NAL).
