We're almost at 3lbs MVER, so what if the rH is over 90% ?

Service condition for a hospital in the midwest is temperature between 63 and 78 degrees and RH between 30% and 60%.

If you take the new ASTM at literal meaning, that's where the readings should fall. Nowhere does it say you need an HVAC system.

I have been on job sites that they had an HVAC system running and I couldn't conduct any testing. The RH was too high or the temperature was too high or low. On several jobs the GC baked the buildings and the temperature was over 100 degrees. So HVAC isn't really a consideration.

What you need is the slab and the ambient humidity in the range that the facility will be in during operation, and that is pretty easy to hit.
