CALCULATIONS:

Method Details		Observations		Remarks if, any
Guideline	OECD 109	1^stReading	2^nd 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 water at a stated temperature.
Test temperature (°C)	-	20 °C	20 °C
Density of water at test temperature; g/cm^3(ρtw)		0.9982	0.9982
Atmospheric pressure (in hPa)	-	969.0	968.8
Weight of empty dry pyknometer (Wp)		29.254	31.035
Weight of pyknometer filled with water (WA)		79.014	81.132
Weight of pyknometer + test Item (WPS)		32.252	34.199
Weight of pyknometer +test Item+ water (WB)		80.221	82.842
