Accredited efficacy tests
The bactericidal and fungicidal activity of pyroligneous acid (wood vinegar) was tested at Nanolab, a TÜRKAK-accredited laboratory. Tests T25-3971/0 and T25-3972/0 were carried out and reported in line with the Turkish Ministry of Health disinfectant test method. The second EN 1650 result (report T25-3459/0) is taken from the summary in V-Pyro's explanatory sheet.
