ISO FDIS 17094

Description / Abstract: This test method covers the determination of the antibacterial activity of materials that contain an indoor-light-active photocatalytic material or have indoor-light-active photocatalytic films on the surface, by measuring the survival bacteria after illumination with indoor light.

This International Standard is intended for use with different kinds of indoor-light-active photocatalytic materials used in construction materials in flat sheet, board, plate shape that are the basic forms of materials for various applications. It does not include powder, granular, or porous indoor-light-active photocatalytic materials. Also, this International Standard is not applicable for cloths or textiles.

This test method is applicable to indoor-light-active photocatalytic materials produced for antibacterial application. Other types of performance of indoor-light-active photocatalytic materials, i.e. decomposition of water contaminants, self-cleaning, antifogging, and air purification, cannot be determined by this method.
