The EN 13727 standard, a European standard, describes the requirements for the bactericidal activity of chemical disinfectant and antiseptic products, which when diluted with hard water or, in the case of ready-to-use products, form a homogeneous, physically stable preparation with water, and defines a test method. Products can only be 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 field of hygienic handwashing, hygienic handwashing, surgical handwashing, surgical handwashing, instrument disinfection by dipping, and surface disinfection by wiping, spraying, flooding or other means.
This test method is applicable to areas and situations where disinfection is medically indicated. The most common environments are:
This test method also covers service areas such as laundry and kitchen that provide products directly to patients.
The test method defined in the EN 13727 standard is intended to determine the effectiveness of commercial formulations or active substances under the conditions in which they are used.
This test method cannot be used to evaluate the efficacy of products against legionella and mycobacteria in aquatic systems.
While testing, a sample of the product diluted with water for hard water or ready-to-use products is added to the test suspension of bacteria in an interfering agent solution. The mixture is kept at one of the temperatures and contact times specified in the standard. At the end of this contact period, some of it is removed. Bactericidal or bacteriostatic effect in this part, confirmed is immediately neutralized by a method. The number of surviving bacteria in each sample is determined and the reduction calculated.
Our organization also provides quantitative suspension testing services for the evaluation of bactericidal activity in the medical field within the scope of EN 13727 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
