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

"Service Conditions" is probably the only grey area of 2170, but it is up to the customer/GC/Project manager to determine that correctly. But you don't necessarily need HVACs running to produce it.

Interesting that the standard for RH via the hood method (F2420) says "service conditions OR (a stated range of RH and temp) if that's not possible".

I presume that is because both the hood, and the MVER method, are more prone to the surface conditions, than RH at-depth is. Bad grammar, sorry.
