Quantitative determination of antibacterial activity of ceramic tile surfaces - Test methods - Part 2 : ceramic tile surfaces with incorporated photocatalytic antibacterial agents

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
