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. |

Description of key information
The density of test chemical was determined following OECD Guideline 109 and according to theIS 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 0.8665 g/cm³ at 20°C and 973.3 hPa.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.879
Additional information
The density of test chemical was determined following OECD Guideline 109 and according to theIS 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 0.8665 g/cm³ at 20°C and 973.3 hPa.
Other supporting studies from various reliable sources such as authoritative databases and handbooks,the density of test chemical was determined to be in the range of 0.870 g/cm3 to 0.878 g/cm3 to at 20 degree C.
As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density as 0.879 g/cm3 at 20 degree C and 973.3 hpa pressure,thus considered as key study for the chemical safety assessment.
