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 (pycnometer) 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.

Additional information

The density of test item Benzyl phenylacetate (CAS No. 102-16-9)was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision)using glass pyknometer .The mean density of test item was determined to be 1.0702 g/cm³at 20°C and 983.1 hPa.

Other supporting studies from various reliable sources such as handbook and authoritative database also indicates that the density of chemical Benzyl phenylacetate was determined to be in the range of 1.099 g/cm3 to 1.1 g/cm3

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density as 1.0702 g/cm3 at 20 degree C,thus considered as key study for the chemical safety assessment
