本文件规定了评估含有抗菌剂的釉面和无釉面瓷砖表面抗菌活性的试验方法。 本文件不包括抗菌处理对瓷砖表面的次要影响，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。 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 antibacterial agents. Secondary effects on ceramic tile surfaces due to 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. 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.
