Are the ISO tests the only tests which can be performed on my samples?

In addition to the published ISO tests the use of inks to rapidly screen the photocatalytic activity of self-cleaning films can be carried out, details of which are given below under further information.  We can also carry out non-ISO tests such as removal of stearic acid (also for self-cleaning surfaces), destruction of 4-chlorophenol (for powders), or activity vs. usage and activity vs. weathering plots.
