    BS1377: Part 8:  1990  2.1 small pouring cylinder*        
        2.2 large pouring cylinder        
Calibration              
*Mean mass of sand in cone of pouring cylinder  (m2)     g
Volume of calibration container  (V)    (200*200mm)     mL
*Mass of sand + cylinder before pouring (m1)   g
* Mean mass of sand + cylinder after pouring   (m3)     g
*Mass of sand to fill calibrating container   (ma =m1-m2-m3)   g
Bulk density of sand ps =  ma /   V           Mg/m3
Test no.
Mass of wet soil from hole  mw g
*Mass of sand + cylinder before pouring  m1 g
*Mass of sand + cylinder after pouring   m4 g
*Mass of sand in hole (mb= m1-m4-m2) g
Ratio mw  / mb      
Bulk density p = mw/mb * Ps   Mg/m3
Moisture content container no.
Moisture content %
Dry density pd = 100 p / 100+w   Mg/m3
