精细陶瓷（高级陶瓷 高级工业陶瓷）.半导体光催化材料抗菌活性的试验方法

[中文适用范围]： 本文件规定了通过测量紫外光照射下的细菌计数来测定含有光催化剂或表面具有光催化膜的材料的抗菌活性的测试方法。 本文件旨在与平板、板、板状或纺织品的建筑材料中使用的不同种类的半导体光催化材料一起使用，这些材料是各种应用的材料的基本形式。 不包括粉末状、粒状或多孔光催化材料。 该测试方法通常适用于生产抗菌效果的光催化材料。 该方法无法测定光催化材料的其他类型的性能，即抗真菌活性、抗病毒活性、水污染物分解、自清洁、防雾和空气净化等。 本文件中表达的数值符合国际单位制 (SI)。 [外文原描述]： This document specifies a test method for the determination of the antibacterial activity of materials that contain a photocatalyst or have photocatalytic films on the surface, by measuring the enumeration of bacteria under irradiation of ultraviolet light. This document is intended for use with different kinds of semiconducting photocatalytic materials used in construction materials in flat sheet, board, plate shape or textiles that are the basic forms of materials for various applications. It does not include powder, granular or porous photocatalytic materials. This test method is usually applicable to photocatalytic materials produced for antibacterial effect. Other types of performance of photocatalytic materials, i.e. antifungal activity, antiviral activity, decomposition of water contaminants, self-cleaning, antifogging and air purification, are not determined by this method. The values expressed in this document are in accordance with the International System of Units (SI).
