Virucide (EN 14476)
A virucide is a product that inactivates viruses. Under EN 14476, it must reduce the amount of virus at least 10,000-fold (4 log) in a suspension test.
EN 14476 is a quantitative suspension test: the disinfectant is brought into contact with reference viruses at a defined concentration, time and conditions (clean or dirty). The scope of the claim depends on the viruses tested. Viruses with a lipid envelope, such as coronaviruses or influenza, are generally the most sensitive; non-enveloped viruses, such as poliovirus, adenovirus or norovirus, are more resistant. That is why a product that only claims activity «against enveloped viruses» cannot be presented as virucidal against all viruses.
As with bactericides, effectiveness is only proven at the dose and contact time tested, and on previously cleaned surfaces. To market a disinfectant in Spain, its authorisation and registration number are also required.
