Fine Ceramics (Advanced Ceramics, Advanced Technical Ceramics). Determination of antiviral activity of semiconducting photocatalytic materials. Test method using bacteriophage Q-beta
The test method in this International Standard specifies the determination of the antiviral activity of materials that contain photocatalytic materials or have photocatalytic films on the surface, by enumerating the destruction of bacteriophage Q-beta after irradiation of ultraviolet light.
NOTE In this test method, the surrogate microbe is bacteriophage Q-beta, intended as a model for Influenza viruses.
The test method in this International Standard 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.
The test method in this International Standard 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 test method.
The values expressed in this International Standard are in accordance with the International System of Units (SI).
