ISO 21702 – SARS-CoV-2 Testing
On glass surfaces, SARS-CoV-2 can survive for up to 28 days. Independent laboratory testing in United States completed the testing on ceramic-based antimicrobial window films’ capability.


← When tested on non-porous control materials, the survival rate of SARS-CoV-2 on conventional window films and other non-porous surfaces, is close to 100% after 24 hours.
