Am I correct that HEPA-filters are classified using US MERV-rating in ETIM? I base my understanding to value H13 that is only used with classes EC010580, EC011234 and EC011236 leaving basically panel/frame-filters w/o HEPA-classification/attributes. I would suggest adding ISO 1822 and perhaps also ISO 29463 to all filters that are panel/frame, bag or cartridge.

I am no expert in the field, but what I can find is that the filter classes used are according to EN779 or EN1822 (the latter relevant for HEPA filters). See screenshot attached as example. ISO classification can of course be added, please contact your local ETIM office for any change requests to the ETIM model.
