Description / Abstract:
This method covers determination of the specific gravity of
soils composed of particles smaller than the 4.75-mm (No. 4) sieve
by means of a pycnometer. When the soil is composed of particles
larger than the 4.75-mm (No. 4) sieve, the method outlined in T 85
shall be followed. When the soil is composed of particles both
larger and smaller than the 4.75-mm (No. 4) sieve, the sample shall
be separated on the 4.75-mm (No. 4) sieve, the appropriate test
method should be used on each portion, and a weighted average
should be calculated.
The values stated in SI units are to be regarded as the
standard.
