Test method 
  BS1377: Part 9:  1990  2.3  

Ring diameter   Depth of hole mm (if specified:Yes/No*)
Volume of test hole       Wet mass of material      
1. Surface correction   Material + drum 1 kg  
  Initial volume of water in ring above   Drum 1 kg Material kg
  prepared surface              
  (Ri) L Material + drum 2 kg  
            Drum 2   kg Material   kg
2. Test hole + ring                  
  Final volume of water in hole   Material + drum 3 kg  
  and density ring   Drum 3 kg Material kg
  (Rf) L            
  (Alternative: hole + ring-oversize Material + drum 4 kg  
  material (Rp) L) Drum 4 kg Material kg
3. Total volume of test hole:        
  Vh = Rf - Ri = m3 Wet mass of total material (mw) kg
Moisture content         Mass and volume of oversize material  
Container no:         Specified size limit   BS Sieve
Mass of wet soil + container     g Container no.  
Mass of dry soil + container     g Method of separation:  
Mass of container       g    
Mass of moisture       g Mass of oversize material (ms) Kg
Mass of dry soil       g Volume of oversize material (vs) m3
For total material    
Moisture content (w) %    
For smaller than specified size    
Moisture content (wp) %    
For total material : For material finer than specified limit:  
  (a) Where oversize material replaced in hole:  
Bulk density (p) = mw = Mg/m3 Dry density =  mw - ms 100 Mg/m3
  Vh * 1000   Rp-Ri 100 + Wp  
  (b) Where volume oversize material obtained separately
Dry density (pd) = p*1000 Mg/m3 Dry density = mw - ms 100 Mg/m3
  100 + w   Vh - Vs 100 + Wp  
* Delete as appropriate
  Operator Checked Approved
