TruFade - ISO B02 105 A3 Filters

What filters do I use when conducting the colour fastness to light test simulating sub-tropical conditions - ISO B02 105 A3?

The filters can be placed in any configuration within the holder regardless of filter ratios. However is advisable to try to balance them out evenly where possible.

This is a filter configuration example and our recommendation for a UG11:KG1 - 5:2 filter ratio that may be used in the ISO B02 105 A3, however other ratios & configurations may also be used. Other standards may require different filter types.

Please note that the UG11 positioning picture if for illustration only as it shows clear filters and not the black UG11 filters:
