Scope

This document describes the test method for evaluating the antibacterial activity of antibacterial agents on the surfaces of glazed and unglazed ceramic tiles.
This document does not cover the secondary effects on the tile surfaces caused by antibacterial treatment, such as chemical corrosion resistance, pollution resistance, or minor color changes. For chemical corrosion resistance, see ISO 10545-13; for pollution resistance, see ISO 10545-14; and for minor color changes, see ISO 10545-16.
The test results obtained through this document are only applicable to this document and the test conditions specified therein. The test results indicate the antibacterial activity under specific test conditions, which may not reflect the activity under various factors such as temperature, humidity, different bacterial species, and nutritional conditions.
