1.1 these test methods cover the laboratory determination of the water moisture content by mass of soil, rock, and similar materials where the reduction in mass by drying is due to loss of water except as noted in 1.4, 1.5, and 1.8. for simplicity, the word material shall refer to soil, rock or aggregate whichever is most applicable.

So, knowing the relative humidity rh conditions is a must when trying to determine what a safe moisture content for wood walls is. for example, if the temperature in the room is around 80 degrees fahrenheit, and the rh is 50, then a safe level of moisture in the wall would be about 9.1 mc.
