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 substance 1-(1-naphthyl)ethanone (CAS No. 941-98-0)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 substance 1-(1-naphthyl)ethanone was determined to be 1.1144g/cm³ at 20°C and 972.3 hPa.
Other supporting from various reliable sources such as authoritative database and handbooks suggests that the density of chemical 1-(1-naphthyl)ethanone was reported to be in the range of 1.117 g/cm3 to 1.1338 g/cm3 ,and the selected key study value lies in the range as mentioned above.
As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density as 1.1144 g/cm3 at 20 degree C,thus considered as key study.
