Fine Ceramics (Advanced Ceramics, Advanced Technical Ceramics) — Determination of antiviral activity of semiconducting photocatalytic materials — Part 2: Test method using influenza virus and feline calicivirus. ISO/WD 18061-2

Scope

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 of titre of virus after irradiation of ultraviolet light using the virus that can infect animal cells. Due to the individual sensitivities, the results of one test virus might not be applicable for 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 shape 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 antiviral applications. 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).
