MOISTURE CONTENT TEST - GB/T18102-2007 (6.3.3) and GB/T17657-1999 (4.3); EN 13183-1:2002 (adapted)

1. TOOLS
1.1 Balance accurate to 0.01 gr.
1.2 Equipment for drying wood, ensuring free internal circulation of air and capable of maintaining a temperature of 103 (+/-2) ° C

SAMPLING
3*100x100 mm

3. TESTING PROCEDURE
3.1 Weigh samples (W0)



3.2 Oven-dry samples for 6 hours at 103 (+/-2) ° C



3.3 Record samples’ weight (W1)



3.4 Repeat steps 3.2-3.3 until the difference in mass between 2 successive weighings (WF and WF-1) separated by an interval of 2 hours is less than 0.1%
3.5 Weigh the sample (WF)



3.6 Moisture Content (%) = ((W0 – WF)/WF)*100

4. ASSESSING TEST RESULTS
Passing requirement: 3-10% or per the contract
