Soil
% finer than #200 sieve
A specimen of the soil is washed over a 75-um (No. 200) sieve. Clay and other particles that are dispersed by the wash water, as well as water-soluble materials, are removed from the soil during the test. The loss in mass resulting from the wash treatment is calculated as mass percent of the original sample and is reported as the percentage of material finer than a 75-um (No. 200) sieve by washing.
