Project Description
The main scope of the INTEC project is to explore the utilisation of photocatalyst indicator inks in a CEN standard for the rapid testing (albeit semi quantitative) of the activities of various different self-cleaning surfaces, including: glass, tiles, paints, fabrics and concrete. The formulations of all the inks will be given in the standard, so that anyone can make and use them. New, previously unreported photocatalyst indicator inks will also be provided for round robin testing by the consortium members. To date, no rapid screening method for assessing photocatalyst activity outside the use of such inks exists. To our knowledge ISO and CEN have no plans at present to introduce a standard based on these inks, although many members of the photocatalyst community and relevant ISO and CEN communities use them.
PROJECT OBJECTIVES
The key project objectives are as follows:
- Prepare and test different photocatalyst inks for round robin tests
- Prepare typical photocatalyst samples based on glass, tiles, paint, concrete and fabrics for round robin tests
- Conduct a series of round robin tests which identifies the best inks and protocol for each very different coating substrate
- Engage with and present findings to relevant CEN committee (TC386) and use feedback to improve on the prepared draft standard
- Have accepted by CEN/TC386 a CEN standard for subsequent processing on photocatalyst activity-measuring inks
