You cannot interpret the ASTM's as you feel they should be. The old MVER test never required grinding and never required HVAC. The new 2170 doesn't require HVAC.
If the temp is 70 and the humidity is 50, HVAC does nothing for you.
Well, did you actually read the new ASTM or are your making that up?
