Résumé

This document specifies the determination of the antiviral activity of materials that contain indoor-light-active photocatalytic materials or have indoor-light-active photocatalytic films on the surface by measuring the infectivity titre of virus after illumination with indoor 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 indoor-light-active 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 indoor-light-active photocatalytic materials. This document is applicable to indoor-light-active photocatalytic materials produced for an antiviral applications. Other types of performance of indoor-light-active 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 document are in accordance with the International System of Units. (SI)
