In the European standard EN 17111, the requirements for the virucidal activity of chemical disinfectant products that form a homogeneous, physically stable preparation when diluted with hard water or, in the case of ready-to-use products, with water, are described and a test method is defined. This test method applies to products used for disinfection of instruments by immersion in the medical field.
Such symptoms occur in patient care. 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 17111 standard is intended to determine the effectiveness of commercial formulations or active substances on viruses under the conditions in which they are used. This method corresponds to a phase 2, step 2 test.
Meanwhile, another European standard, EN 14885, contains details for using the interrelationship of various tests and recommendations..
A test suspension of test viruses in a solution of substances that interfere with testing is spread on a glass carrier. After drying, the carrier is immersed in the delivered product sample or diluted with hard water (water for ready-to-use products). In parallel, a second carrier is treated with hard water instead of the product applying the same test conditions. The carriers are kept at one of the temperature and contact times specified in the standard. At the end of this contact period, the carriers are transferred to a care medium containing glass beads. Viruses should be separated from the surface by shaking. The number of surviving viruses in each sample is determined and the reduction calculated by comparing the results of the product and water control.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides quantitative carrier testing services for the evaluation of virucidal activity for medical instruments within the scope of EN 17111 standard, with its trained and expert staff and advanced technological equipment.
