Efficacy Test for Disinfectants according ECHA Guideline (PT 2, 5 & 11 and more)

The SUT Simulated Use Test GmbH carries out efficacy tests of disinfectants (biocides) in aquatic systems. Among our portfolio we offer tests for the disinfections of drinking water (product type 5), swimming pool water (product type 2) and cooling water (product type 11), which are subject to approval in accordance with the EU Biocidal Products Regulation 1.) For authorization, products must demonstrate sufficient efficacy according defined test criteria which are specified in the ECHA Guideline 2.) The SUT Simulated Use Test GmbH offers the efficacy test according to the ECHA guideline.

The simulated use tests are carried out at various test stands (disinfectant test rigs), which operate on flow-through mode. The tests are carried out according to the specifications of guidelines or in correspondence with our customers. Crucial parameters such as pH, DOC, temperature, contact times, etc. as well as defined microorganisms are monitored (Escherichia coli, Enterococcus faecium, bacteriophages MS2, PRD1).

After execution, a test report is prepared, which can be submitted to the competent authority (i.e. Federal Office for Chemicals at the Federal Institute of Occupational Safety and Health (BAuA)) within the framework of the authorization of biocidal products. Our offer is therefore aimed in particular at manufacturers or distributors of disinfectants subject to authorization in accordance with the EU Biocidal Products Regulation.
We have many years of experience in determining the microbiological effectiveness of disinfectants in drinking water, swimming pool water and cooling water.

The underlying principle of the procedure is recommended as simulated use test for products in swimming pool water (product type 2) according to the OECD Guideline 3.) (Series on Testing and Assessment No. 170; Series on Biocides No. 4). The OECD Guidance therefore also applies according to the ECHA Guideline.

Also for this application we offer the test in the flow-through principle with adjusted operating conditions, such as shorter contact times, higher temperatures and with further test organisms.
