Determination of Antiviral Activity of Photocatalytic Materials
Q-beta phage test method
Warning: Only those who have been trained in microbiological skills can carry out the test of this method:
1 Scope
This document describes the test method for the antiviral activity of surfaces containing photocatalysts or coated with photocatalysts or photocatalytic materials:
This method determines its antiviral activity by counting the reduction of Q-beta phage after ultraviolet light irradiation:
Note: In this test method, Q-β bacteriophage is used as a substitute virus for influenza virus:
This document is applicable to different types of semiconductor photocatalytic materials used in building materials, and its basic shapes include sheet, block or flat
etc:, but does not include powders, granules or porous photocatalytic materials:
This document is applicable to the detection of photocatalytic materials with anti-virus properties, not applicable to anti-bacterial, anti-fungal, degradation of pollutants in water, self-
Detection of cleaning, anti-fog and air purification performance:
Quantities expressed in this document are in International System of Units (SI) units:
