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的空气净化性能，这些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，在长波紫外线（UV）照射下，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，这些材料是各种应用的基本材料形式。本文件还适用于结构化过滤材料，包括蜂窝结构、机织物和无纺布，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。交叉引用:ISO 2718:1974ISO 4677-1:1985ISO 4892-3ISO 6145-7: 2001ISO 10677:2011ISO/IEC 17025:2005ISO 22197-1:2007ISO 80000-1:2009购买本文件时可获得的所有现行修订均包含在购买本文件中。

This document 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 irradiation with long-wave ultraviolet (UV) light. 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.Cross References:ISO 2718:1974ISO 4677-1:1985ISO 4892-3ISO 6145-7:2001ISO 10677:2011ISO/IEC 17025:2005ISO 22197-1:2007ISO 80000-1:2009All current amendments available at time of purchase are included with the purchase of this document.
