Soil
Grain Size
This test method covers the quantitative determination of the distribution of particle sizes in soils. The distribution of particle sizes larger than 75-µm (retained on the #200 sieve) is determined by sieving, while the distribution of particle sizes smaller than 75-µm is determined by a sedimentation process, using a hydrometer to secure the necessary data.
