Method Details		Observed Values
		1st Observation	2nd Observation
Guideline	OECD 109
Method	IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision)
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.

Conclusions:

The density of chemical was determined following OECD Guideline 109 and IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) according to the using glass pyknometer. The mean density of the test item was determined to be 1.056 g/cm³ at 20°C and 978.9hPa

Executive summary:

The density of chemical was determined following OECD Guideline 109 and IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) according to the using glass pyknometer The mean density of the test item was determined to be 1.056 g/cm³ at 20°C and 978.9hPa

Description of key information

The density of chemical was determined following OECD Guideline 109 and IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) according to the using glass pyknometer The mean density of the test item was determined to be 1.056 g/cm³ at 20°C and 978.9hPa.

Key value for chemical safety assessment

Additional information

In an experiment,the density of chemical was determined following OECD Guideline 109 and IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) according to the using glass pyknometer The mean density of the test item was determined to be 1.056 g/cm³ at 20°C and 978.9hPa.

Other supporting studies suggests that the density of chemical was reported to be in the range of 0.991- 0.994 g/cm3 at 25 degree C.

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density 1.056 g/cm3 at 20 degree C, thus it is considered as key study for the chemical safety assessment.
