1.	Guideline	OECD 109
2.	Method	IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision)
3.	Principle of Method	Determination of the mass at a given temperature of a volume of the material contained in a density bottle (pyknometer) and determination of the volume of the latter by determining the mass of the corresponding volume of water at the same temperature. The density is obtained by dividing the mass of material by its volume.

*ρ_at=density of air at 27°C and 760 mm Hg pressure=0.001168 g/cm³

**Density of water referred from the Table 1 of the IS method.

Conclusions:

The density of test chemical was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) using glass pyknometer. The mean density of test chemical was determined to be 0.9497 g/cm³ at 20°C and 977.4 hPa.

Executive summary:

The density of test chemical was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) using glass pyknometer. The mean  density of test chemical was determined to be 0.9497 g/cm³ at 20°C and 977.4 hPa.
