Moisture Content

Oven-dry & rapid moisture methods per ASTM D2216

Test Level
Standard lab procedure
💧
STEP 1/2
Moisture Content Test
Determine water content by oven-dry method (105-110°C for 24 hrs)
💧
Enter Sample Weights
Input wet and dry sample weights to calculate moisture content per ASTM D2216.
📝 ASTM D2218 Method
  • Standard oven: 105-110°C for 24 hours to constant weight
  • Rapid methods (IR, microwave) require correlation to oven method
  • Moisture content = (Wet weight - Dry weight) / Dry weight × 100%
  • Typical range: 5-40% for most soils, up to 100%+ for organic/clay soils
