JIS K 6955:2006 Plastics -- Determination of the ultimate aerobic biodegradability in soil by measuring the oxygen demand in a respirometer or the amount of carbon dioxide evolved
This standard specifies a method for determining the ultimate aerobic biodegradability of pubtech materials in soil by measuring the amount of oxygen consumed or the amount of carbon dioxide evolved using a closed respirator. This machine is designed to maximize biodegradation by adjusting the moisture content of the soil. …
