本文件规定了评估含有光催化抗菌剂的釉面和无釉面瓷砖表面抗菌活性的试验方法。 本文件不包括光催化抗菌处理对瓷砖表面的二次影响，如耐化学性、耐染色性或微小色差的变化。耐化学性参考ISO 10545-13，耐染色性参考ISO 10545-14，色差参考ISO 10545-16。 本文件不包括光催化陶瓷的其他类型性能，即水污染物分解、自清洁、防雾和空气净化。它也不用于评估已使用局部消毒剂或可在有限时间内提供残余活性的试剂处理过的陶瓷表面。 使用本文件获得的任何结果将始终参考本文件和使用的条件。根据本文件获得的结果表明，在本文所用的特定实验条件下，具有抗菌活性，但不反映在考虑了各种因素（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。

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.
