Phạm vi áp dụng / Scope of standard

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.
