Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From August 12 to 13, 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. The substance is adequately characterised with its isomers composition. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected on November 29 and 30, 2010 / signed on April 11, 2011
- Type of method:
- pycnometer method
- Dynamic viscosity of test material:
- (no data)
- Key result
- Type:
- relative density
- Density:
- 0.895 other: relative density is dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The test substance is much less dense than water.
- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method.
Experiment was performed at 20 °C in duplicate, and the mean density was calculated. Relative density was converted vs water at 4°C.
The density of the test substance was determined as 0.8950 g/cm3 at 20.0°C, and d20/4 is 0.895.

- Relative density at 20C:
- 0.895
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study. The result is retained as key data.
