Laboratory testing is one of the best ways to ensure the solution you are producing with your machine is doing the work you want it to do. The European Union has established a set of tests that qualify disinfectants for specific pathogen eradication. These European Norm standards (often referred to as EN tests) are one way to indicate your legitimacy as a disinfectant producer and to provide your customers with peace of mind. You can have your solution tested at private or public laboratories to these standards.
Several of our partners have tested the hypochlorous produced from the Hypo 7.5 according to these EN standards. For example, in Singapore, the Hypo passed the EN14476. This test evaluates the efficacy of 250 ppm hypochlorous in one minute of contact time against the human coronavirus. HOCl made by the Hypo also passed EN1276 and EN1500, achieving a >5 log reduction on E. coli, P. aeruginosa, S. aureus, and E. hirae (test EN1276). Similar results have been obtained by our customers in Greece and Kenya. In Greece, the hypochlorous produced in the Hypo 7.5 passed the EU requirements for biocidal disinfection. In Kenya, it was approved by the Kenyan Bureau of Standards after achieving a 7.5 log reduction on the standard test for chemical antiseptics and disinfectants.
It is interesting to note that while hypochlorous can’t kill all yeasts and molds (see our blog post on mold for more information), it did kill 99.90% of Candida albicans and Aspergillus brasiliensis in the EN1650 test in Singapore. This is a 3 log reduction and a fantastic outcome for real-life applications. Unfortunately to pass the EN test, it needed to kill 99.99% of the specimens (instead of 99.90%), so our partner will need to try that test again.
