1. Obtain 15 to 40 grams of oven-dried sample. For clayey samples use a less sample, for siltier samples use more. The sample should be wet-sieved to remove sand-size particles prior to the test. 2. Transfer the sample to a 250 ml beaker, add 1 gram of sodium hexametaphosphate and approximately 150 to 200 ml of deionized water, and
