标准范围

本文件规定了一种测试方法，用于测定含有光催化剂或表面有光催化膜的材料（通常由半导体金属氧化物制成，如二氧化钛或其他陶瓷材料）的空气净化性能，以去除乙醛，在室内光照下，将试样连续暴露于模型空气污染物中。本文件适用于不同类型的材料，如平板、木板或平板形状的建筑材料，这是各种应用材料的基本形式。本文件也适用于蜂窝状材料，以及含有陶瓷微晶和复合材料的塑料或纸质材料。本文件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、自发光-清洁、防雾和抗菌作用。

This document specifies a test method for the determination of the air-purification performance, with regards to removal of acetaldehyde, 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 from indoor light.This document is intended for use with different kinds of materials, such as construction materials in flat sheet, board or plate shape, which are the basic forms of materials for various applications. This document also applies to materials in honeycomb form, and to plastic or paper materials containing 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.
