 Method Details Observations Remarks if, any Guideline OECD 109 1stReading 2nd Reading Method Adapted from ASTM D854-02 Principle of method The density of test item is determined by using pyknometer. It is the ratio of mass of the unit volume of test item at a stated temperature to mass of the same volume of gas free distilled waterat a stated temperature. Test temperature (°C) - 20°C 20°C Density of water at test temperature; g/cm³ (ρtw) 0.9982 0.9982 Atmosphericpressure (in hPa) - 977.5 975.8 Weight of empty drypyknometer (Wp) 31.114 29.100 Weight of pyknometer filledwith water (WA) 80.755 78.654 Weight of pyknometer + test Item (WPS) 41.010 38.651 Weight of pyknometer +testItem+ water (WB) 78.568 78.455
