ISO 22197-1:2007规定了一种试验方法，通过将试样连续暴露在紫外光照射下的模型空气污染物中，测定含有光催化剂或表面有光催化膜的材料的空气净化性能，这些材料通常由半导体金属氧化物（如二氧化钛或其他陶瓷材料）制成。ISO 22197-1:2007适用于不同类型的材料，例如平板、木板或平板形状的建筑材料，这些材料是各种应用的基本材料形式。 ISO 22197-1:2007也适用于蜂窝形式的材料，以及含有陶瓷微晶和复合材料的塑料或纸质材料。ISO 22197-1:2007不适用于粉末或颗粒光催化材料。 本试验方法通常适用于空气净化用光催化材料。该方法不适用于测定光催化材料的其他性能属性，即水污染物的分解、自清洁、防雾和抗菌作用。它涉及一氧化氮的去除。

ISO 22197 -1:2007 specifies a test method for the determination of the air-purification performance of materials that contain a photocatalyst or have photocatalytic films on the surface, 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 illumination with ultraviolet light. ISO 22197 -1:2007 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. ISO 22197 -1:2007 also applies to materials in honeycomb-form, and to plastic or paper materials if they contain ceramic microcrystals and composites. ISO 22197 -1:2007 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 nitric oxide.
