4. Test Method
Antimicrobial, Antifungal, and Antiviral Activity Tests
The test microorganism is inoculated onto the product surface and allowed to remain for a specified contact time. The number of surviving microorganisms is then determined to evaluate the antimicrobial, antifungal, or antiviral activity of the product.
Fungal Resistance Test
The product is inoculated with fungal spores and incubated for a specified period. Fungal resistance is evaluated based on the extent of fungal growth observed on the product.
Repeated Sanitizing Performance Test
The product is repeatedly challenged by inoculating it with the test microorganism and allowing it to remain in contact for a specified period. After repeated exposure, the product is inoculated once more with the test microorganism, and the number of surviving microorganisms is determined to evaluate its antimicrobial performance.
In addition to standardized methods, we can design customized studies based on our extensive testing experience and scientific expertise to meet the specific objectives and requirements of our clients.
