Moisture identified by nondestructive moisture testing is relative and must be quantified by a combination of physical core cuts and gravimetric analysis.
Gravimetric analysis for roof moisture.
Gravimetric determination of moisture and phosphorus in fertilizer samples.
3 2 1 core a sampl cut e of the roof assem bly extracted from an existing roof system for further analysis including all elements of the roofing system including the deck material only when the deck material is capable of moisture absorption well beyond its equilibrium content.
In the moisture analysis procedure the core cuts are extracted to determine both the construction and moisture content of the existing roof system.
3 2 2 equilibrium moisture content emc.
Without a doubt moisture has one of the greatest negative influences on roof performance.
