Today is increasingly developing, rendering it easier for individuals By lowering the moisture content, we decide to provide or extract some water from the soil to get full compaction. 0000007040 00000 n https://civilblog.org/2013/05/14/moisture-content-test-of-soil-is-2720-part-2-1973 SO, from the above observations and calculations, the mean moisture content of the soil sample is 34.37%. The acceptable range of moisture content in wood flooring is within 2% to 4% of your subfloor’s moisture level. The acetylenes gas produced by the tester is tapped within the tester and registers on the pressure dial, which is calibrated to read directly in percent of moisture by wet weight of soil. Moisture Content Test of Dry Chemical Powder (DCP) as per imo 1432, a sample of DCP has to be tested for moisture content bi-anually. 0000001639 00000 n 0000001221 00000 n + Wt. In the cannabis community there has been a widespread opinion that 12 percent moisture is a good content of water for smoking in a joint that won’t go out — it’s also the percentage at which small sticks audibly snap.
