Summary

This document specifies a test method for the determination of the air-purification performance of
materials that contain a photocatalyst or have photocatalytic films, usually made from semiconducting
metal oxides, such as titanium dioxide or other ceramic materials, by continuous exposure of a test
piece to the model air pollutant under irradiation with ultraviolet light (UV-A).
This document is intended for use with different kinds of materials, such as construction materials in
flat sheet, board or plate shape, that are the basic forms of materials for various applications.
This document also applies to structured filter materials including honeycomb-form, woven and non-
woven fabrics, and to plastic or paper materials if they contain ceramic microcrystals and composites.
This document does not apply to powder or granular photocatalytic materials.
This test method is usually applicable to photocatalytic materials produced for air purification.
This method is not suitable for the determination of other performance attributes of photocatalytic
materials, i.e. decomposition of water contaminants, self-cleaning, antifogging and antibacterial
actions. It concerns the removal of acetaldehyde.
