Technically nowhere in the ASTM does it say the space must have the HVAC on.
We wouldn't want testers thinking they cannot conduct accurate RH testing just because the HVAC is not on. In 99% of all the hospitals I work in, the HVAC is not commissioned until a few days before the building is turned over.
