The results of laboratory tests carried out on test surfaces made of stainless steel, tile and metlakh tile, wood, concrete are presented. As test microorganisms, museum cultures of Escherichia coli (strain 1257), Staphylococcus aureus (strain 209R), Mycobacteria (strain B-5), B. сereus (pcs. 96) were used. In the course of the experiments, disinfection regimes (concentration, exposure, consumption of disinfectant) were established for disinfecting smooth and rough surfaces. In this case, effective disinfection of all types of test surfaces contaminated with E. coli and S. aureus was obtained by processing 0,7% solution, respectively, for 1 and 3 hours at a rate of 0,5 liters / m2. Disinfection of test surfaces contaminated with Mycobacteria (strain B-5) and B. cereus (pcs. 96) spores reached 4,0%, respectively, after a single and 5,0% concentration after double treatment at a rate of 0,5 l/m2 for 24 hours exposure.

The results of laboratory tests of Megacid carried out on test surfaces made of stainless steel, tile and metlah tiles, wood, concrete are presented. Museum cultures of Escherichia coli (pieces 1257), Staphylococcus aureus (pieces 209Р), mycobacteria (pieces B-5) and B. cereus (pieces 96) were used as test microorganisms. During the experiments, disinfection modes were established (concentration, exposure, disinfectant consumption) for disinfecting of smooth and rough surfaces. At the same time, effective disinfection of test surfaces of all types contaminated with E. coli and S. aureus was established at treating with 3,0% solution at the rate of 0,5 l/m2, respectively for 1 and 3 hours of exposure. For disinfection of test surfaces contaminated with mycobacteria (pcs. B-5), it was necessary to irrigate simultaneously with 8,0% solution twice with an interval of 1 hour at 24 hours, at the rate of 0,5 l/m2 per irrigation.
