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.


The key project objectives are as follows:
