The EN 1657 standard, a European standard, describes the minimum requirements for determining the fungicidal or yeasticidal activity of chemical disinfectant and antiseptic products that, when diluted with hard water or mixed with water in ready-to-use products, form a homogeneous and physically stable preparation; and A test method is defined. Such products are only tested at 80 percent concentration or less because some dilution is always produced by adding test organisms and interfering substances.
This standard covers products used in the veterinary field, such as the raising, breeding, transport and destruction of all animals, unless they are included in the food chain following entry into the slaughter and processing industry.
This test method aims to determine the efficacy of commercial formulations or active substances under the conditions in which they are used.
In the application of this standard, the terms and definitions in the standard "EN 14885 Chemical disinfectants and antiseptics - Application of European standards for chemical disinfectants and antiseptics" are valid.
This test method uses candida albicans and aspergillus brasiliensis as obligate organisms for fungicidal activity and candida albicans fungal species for levuricidal activity. Other mushrooms are optionally used. The test is carried out at a mandatory temperature of 10 degrees and for a mandatory period of 30 minutes. In addition, optionally with additional temperatures of 4, 20 or 40 degrees and optionally with additional times of 1, 5, 15 or 60 minutes, the test is carried out. The test is performed in simulated low-soil or high-dirty conditions.
Within the scope of EN 1657 standard, our organization, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, It also provides quantitative suspension testing services to evaluate the fungicidal or yeasticidal effectiveness of chemical disinfectants and antiseptics used in the veterinary field.
