Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for air-purification performance of semiconducting photocatalytic materials — Part 1: Removal of nitric oxide (ISO 22197-1:2016)
This document specifies a test method for the determination of the air-purification performance ofmaterials that contain a photocatalyst or have photocatalytic films on the surface, usually made fromsemiconducting metal oxides, such as titanium dioxide or other ceramic materials, by continuousexposure of a test piece to the model air pollutant under illumination with ultraviolet light. Thisdocument is intended for use with different kinds of materials, such as construction materials in flatsheet, board or plate shape, that are the basic forms of materials for various applications. This documentalso applies to materials in honeycomb-form and to plastic or paper materials if they contain ceramicmicrocrystals and composites. This document does not apply to powder or granular photocatalyticmaterials.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 photocatalyticmaterials, i.e. decomposition of water contaminants, self-cleaning, antifogging and antibacterialactions. It concerns the removal of nitric oxide.
