TEST ITEM DESCRIPTION AND RESULTS

FOR LIQUIDS:

By Pyknometer Method:

 1 Guideline OECD 109 1stReading 2nd Reading 2 Method Adapted from ASTM D854-02 3 Principle of method The density of test item is determined by using pyknometer. It is the ratioof mass of the unit volume of test item at a stated temperature to mass of the same volume of gas free distilled water at a stated temperature. 4 Test temperature (°C) 20.0°C 20.0°C 5 Atmosphericpressure ( hPa) 972.5 970.3 6 Density of water attest temperature;g/cm³ (ρtw) 0.9982 0.9982 7 Weight of empty dry Pyknometer(Wp) g 29.267 29.263 8 Weight of pyknometer filled with water (WA) 78.762 79.018 9 Weight of pyknometer + test item (WPS) g 34.244 34.052 10 Weight of pyknometer +test Item+ water (WB) 79.688 80.388
