 TEST ITEM DESCRIPTION AND RESULTS

FOR SOLIDS: Density by Pyknometer:

S. No.	Method Details		Observed Values
			1^stObservation	2^ndObservation
1.	Guideline	OECD 109
2.	Method	Adapted from ASTM D854-02
3.	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.
4.	Test temperature		20 °C	20 °C
5.	Density of water at test temperature; g/cm³ (ρtw)		0.9982	0.9982
6.	Atmospheric pressure (in hPa)		965.8	967.3
7.	Weight of empty dry pyknometer (Wp)		31.073	29.370
8.	Weight of pyknometer filled with water (WA)		80.742	79.230
	Weight of pyknometer + test Item (WPS)		33.992	32.428
9.	Weight of pyknometer +test Item+ water (WB)	g	81.316	78.703
