ISO 21702 is a unified test protocol that measures antiviral activity on non-porous and plastic surfaces, designed to provide protection against viruses.
Many epidemiological data and studies have confirmed that viruses can remain viable on a variety of porous and non-porous surfaces for several hours to a few days. In the case of latest COVID 19 outbreak, exposure to virus-infected surfaces is identified as a crucial risk factor for a high transmission rate of infection.
Hence, antiviral coating surfaces are innovated to prevent the spread of viral infection through inanimate surfaces. Standard protocols like ISO 21702 are used to evaluate the antiviral activity of non-porous surfaces incorporated with antiviral additives.
Whereas, ISO 22196 is a standard protocol used for the measurement of antibacterial activity on plastics and other non-porous surfaces
