This test method specifies the determination of the antiviral activity of materials that contain photocatalytic materials or have photocatalytic films on the surface, by enumeratng the destruction of bacteriophage Q-beta after irradiation of ultraviolet light. This test method is intended for use with different kinds of semiconducting photocatalytic materials used in construction materials, in flat sheet, board or plate shape that are the basic forms of materials for various applications. It does not include powder, granular or porous photocatalytic materials. This test method is applicable to photocatalytic materials produced for an antiviral application. Other types of performance of photocatalytic materials, i.e., antibacterial activity, antifungal activity, decomposition of water contaminants, self-cleaning, antifogging and air purification, are not determined by this method. The values expressed in this standard are in accordance with the International System of Units (SI).
