Method Details		Observations		Remarks if, any
Guideline	OECD 109	1^stReading	2^nd Reading
Method	Adapted from ASTM 854-02
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^oC	20^oC
Atmospheric pressure (in hPa)	-	969.6	969.8
Weight of empty dry pyknometer (Wp)		29.048	29.267
Weight of pyknometer filled with water (WA)		79.230	79.169
Weight of pyknometer + test Item (WPS)		34.059	33.873
Weight of pyknometer +test Item+ water (WB)		70.402	71.031
