瓷砖表面抗菌活性的定量测定.试验方法.第2部分：含有光催化抗菌剂的瓷砖表面

[中文适用范围]： 本文件规定了评估掺有光催化抗菌剂的釉面和无釉瓷砖表面抗菌活性的测试方法。 本文件未涵盖光催化抗菌处理对瓷砖表面的二次影响，例如耐化学性、耐污性或微小色差的变化。 有关耐化学性，请参阅 ISO 10545-13；有关耐污性，请参阅 ISO 10545-14；有关色差，请参阅 ISO 10545-16。 光催化陶瓷的其他类型的性能，即水污染物的分解、自清洁、防雾和空气净化，不在本文件的范围内。 它也不适用于评估经过局部消毒剂或可在有限时间内提供残留活性的试剂处理的陶瓷表面。 通过本文档获得的任何结果将始终参考本文档和所使用的条件。 本文件获得的结果表明在本文使用的特定实验条件下的抗菌活性，并不反映在考虑多种因素（例如温度、湿度、不同细菌种类、营养条件等）的其他情况下的活性。 [外文原描述]： This document specifies test methods for evaluating the antibacterial activity of glazed and unglazed ceramic tile surfaces with incorporated photocatalytic antibacterial agents. Secondary effects on ceramic tile surfaces due to photocatalytic antibacterial treatments, such as changes in chemical resistance, stain resistance or small colour differences, are not covered by this document. For chemical resistance refer to ISO 10545-13, for stain resistance refer to ISO 10545-14 and for colour differences refer to ISO 10545-16. Other types of performance of photocatalytic ceramics, i.e. decomposition of water contaminants, self-cleaning, antifogging and air purification, are not covered by this document. It is also not intended to be used to evaluate ceramic surfaces that have been treated with topical disinfectants or agents that can offer residual activity for limited periods. Any results obtained with this document will always refer to this document and the conditions used. Results obtained with this document indicate antibacterial activity under the specified experimental conditions used herein, and do not reflect activity under other circumstances where a variety of factors, such as temperature, humidity, different bacterial species, nutrient conditions, etc., are considered.
