ึ7. Sample Preparation
7.1 Sieve approximately 200 g of soil through a 2.00 mm (No.10) sieve. If materials are quite moist, this may require hand rubbing or use of a rubber-tipped pestle to force material through the sieve. It is recommended that this test be performed at natural water content. When samples are very moist, they should be dried to about the plastic limit before proceeding with the test.
