Parameter-Units Procedure-Reference
Sample Preparation Samples were air dried at less than 35' C. Clods
were broke up prior to grinding and sieving of
sample. Large coarse fragments were removed. Sample
material was sieved. Remaining rock coarse fragments
left on the 10 mesh (2 mm) sieve were removed.
Remaining soil clods left on the 10 mesh screen were
ground until the sample just passed the screen.
Excessive grinding of sample material was avoided
during the entire sample preparation procedure.
