This may be more of a question for the lab guys, but we were discussing how to properly quantify the organic content in silts and clays. Per ASTM D2487-06, the sample must have a second oven dried sample for testing of the Atterberg Limits. My question is, if you oven-dry the second sample at 110 degrees Celcius, how are you supposed to treat the first sample? Do you ove-dry it at a lower oven temperature or do you run it as is right of the bag, no sieving or drying. I have compared both the ASTM D4318 - 10 to the ASTM D2487-06 and haven't really noticed a difference. Any help would be great. Thanks in Advance
