- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14/8/2013 to 8/10/2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- 2012
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- buoyancy method
- Type:
- density
- Density:
- 996.7 kg/m³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 0.997
- Temp.:
- 20 °C
- Conclusions:
- The density of the test item was determined to be 996.7 kg/m3 at 20°C, and the relative density 0.997.
- Executive summary:
The density of the test item was determined by Immersed body method (a buoyancy method for liquids) according to the OECD guideline 109. A glass sphere with a volume of 11.369 cm3was immersed in the liquid test substance for the calculation of the density. The test was repeated three times and the respective results were averaged. The density of the test item was determined to be 996.7 kg/m3 at 20°C.
The study is reliable without restrictions (Klimisch 1), as it follows a standard test guideline.
