Methods for determining moisture in roofing materials measurement and limitations key words.
Moisture identified by non destructive moisture testing is relative and must be quantified by a combination of physical core cuts and gravimetric analysis.
Cut from the roof area.
3 2 2 equilibrium moisture content emc.
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.
Ore cuts are conducted in a roof analysis because each of the moisture analysis methods has their limitations and thorough diagnosis of a roof system requires core cuts.
Gravimetric determination of moisture and phosphorus in fertilizer samples.
Without a doubt moisture has one of the greatest negative influences on roof performance.
