This test is designed to separate soil into its three basic mineral fractions:
sand, silt, and clay. The amount of time required for the soil particles of
various sizes to settle in the soil separation tubes forms the basis for this
test. From the amount of material collected in each tube it is possible to
determine the approximate percentage of each fraction as represented in
the original soil sample.
The procedure for preparation of the soil sample for testing is described in
the accompanying handbook, A Study Of Soil Science.
The separation tubes should be marked for identification in the following
manner: Mark the first sedimentation tube “A”, the second “B”, and the
third “C”.
PRO CE DURE
1. Place the three Soil Separation Tubes in the rack.
2. Add the soil sample to Soil Separation Tube “A” until it is even with
line 15.
NOTE: Gently tap the bottom of the tube on a firm surface to pack
the soil and eliminate air spaces.
