FIELD INSPECTION REPORT

INSPECTOR: Ron Andree/ OBOA# 789
WOOD MOISTURE
CTI representative was onsite this date to perform wood moisture testing in plywood sheathing at roof, (3)
walls (OSB). CTI tested sheathing truss OSB and bottom cord at each location of the roof underside. CTI also
checked moisture in wall sheathing and studs at north, south, east, west and SW angled wall. CTI used a J-
2000 Moisture Meter to take readings. The air temperature was 45° F and the humidity was 69 %. Temperature
of materials was between 47° F and 46° F. See field check list for locations and moisture content %.

Disclaimers:
n Treated Wood
Wood products that have been treated with preservatives, fire retardants, or dimensional stabilization agents may give abnormal
readings (usually high). Readings taken under these conditions should be considered qualitative or semiquantitative at best. Even if
Conductance meters with insulated pins are used, accuracy could only be confirmed through direct MC determination (for example,
Test Methods D 4442).
N R W ood w /Adhesives
Adhesives can cause abnormally high readings in reconstituted wood products. Readings taken on these products should be
considered qualitative or semiquantitative, unless the particular meter used is calibrated to the particular product being tested. CTI
has not calibrated its meters to any reconstituded materials.
C onductance Meter limitations
1) The range of moisture contents that can be detected with a conductance meter, is from a minimum of 6 or 7 % MC to a maximum
of 25 to 27 % MC (nominal value of the fiber saturation point). Meter scales extend above this limit only to permit temperature
corrections of moisture contents up to the fiber saturation point; numbers above that point are not to implied to be reliable.
2) If drift was noted during testing, the highest numbers noted were reported per ASTM D7438 (X2)
3) If readings are believed to be abnormal, and upon request, an additional test can be performed to determine `normal' moisture
gradient in the material tested.
D ielectric Meter limitations
1) The normal range of moisture sensing in dielectric meters is from 0 % to fiber
saturation point Semi - quantitative readings above fiber saturation point are possible with the dielectric meter.
2) Dielectric meters are subject to `read- through'. Surrounding materials can have a major impact on the numbers obtained. Numbers
reported are for the as- described conditions and if surrounding materials are undetermined, the accuracy of the numbers obtained
cannot be deemed accurate.
3) Warped members were measured from both sides when possible and the higher number reported.
Ti Use on other materials
Readings taken under these conditions are considered qualitative only!
