WebAfter we assess the Indoor and outdoor “Raw count”, we look at the Count/M3. Notice the indoor sample volume is 75 liters and outdoor is 150 liters. This count represents how many mold spores are in a cubic meter of air through statistical analysis. This is helpful when samples are taken at different volumes. Webstandardized. The LL is determined in the laboratory by measuring the moisture content at which a standard groove of soil, placed in a standard brass cup, will close when the cup is dropped 25 times from a 0.394 in. height. The PL is determined by measuring the moisture content at which a thread of soil begins to crumble, when rolled into a 1/ 8
