精细陶瓷（高级陶瓷 高级工业陶瓷）.室内照明环境下用半导体光催化材料测定细菌还原率.估算实际环境细菌污染表面抗菌活性的半干法

[中文适用范围]： 该文件建立了一种测定表面含有室内光活性光催化材料的材料抗菌活性的测试方法。 抗菌减少率是通过测量室内光照射后细菌的存活率来确定的。 该测试假设表面很可能使人接触细菌。 该测试旨在评估室内照明环境下使用室内光活性光催化材料对细菌接触感染的抑制作用。 它适用于建筑中使用的不同种类的室内光活性光催化材料，例如平板、板材或板状材料，它们是各种应用材料的基本形式。 它不适用于粉末、颗粒或多孔室内光活性光催化材料以及布料或纺织品。 适用于抗菌用途的室内光活性光催化材料。 其他类型的室内光活性光催化材料应用，即分解水污染物、自清洁、防雾和空气净化，不适合该方法。 [外文原描述]： This document establishes a test method for determining the antibacterial activity of materials containing an indoor-light-active photocatalytic material on the surface. The antibacterial reduction rate is determined by measuring the survival of bacteria after illumination with indoor light. This test assumes a surface with high potential of possible person contact with bacteria. This test is designed to evaluate the suppression of contact infection of bacteria using an indoor-light-active photocatalytic material under indoor lighting environment. It is intended for use with different kinds of indoor-light-active photocatalytic materials used in construction, for example, flat sheets, board or plate shapes, which are the basic forms of materials for various applications. It is not applicable to powder, granular, or porous indoor-light-active photocatalytic materials, as well as cloths or textiles. It is applicable to indoor-light-active photocatalytic materials produced for antibacterial application. Other types of indoor-light-active photocatalytic materials applications, i.e. decomposition of water contaminants, self-cleaning, antifogging, and air purification, are non-applicable by this method.
