WARNING Handling and manipulation of viruses and host cells which are potentially hazardous requires a high degree of technical competence and may be subject to current national legislation and regulations. Only personnel trained in biological techniques should carry out such tests. Appropriate practices for disinfection, sterilization and personal hygiene must be strictly observed. This document specifies the determination of the antiviral activity of materials that contain photocatalytic materials or have photocatalytic films on the surface, by measuring the infectivity titre of virus after irradiation of ultraviolet light using the virus that can infect animal cells. Due to individual sensitivities, the results of one test virus might not be applicable to other viruses. This document is intended for use with different kinds of semiconducting photocatalytic materials used in construction materials, in flat sheet, board, or plate shapes that are the basic forms of materials for various applications. It does not include powder, granular, or porous photocatalytic materials. This document 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 document are in accordance with the International System of Units (SI).
