Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 6-10 August 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is adequately identified, but details on composition are missing. Therefore validation applies with restrictions.
- 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:
- effective 24 July 2009 (validity 18 months)
- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- Storage conditions of test material: Stored at room temperature protected from direct sun light.
- Key result
- Type:
- relative density
- Density:
- 0.849 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The substance is much less dense than water.
- Executive summary:
The density of the test substance was measured under GLP according EU A3 guideline, pycnometer method.
Experiment was performed at 20 °C in duplicate, and compared to water at 4.4°C.
The relative density (D20/4) of the test substance was calculated to be 0.849.

Description of key information
The substance is much less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.849
Additional information
A reliable experimental study, conducted according to a recognized EC method and under GLP, is available.
Despite minor restrictions due to incomplete test item identification, it is considered as a key study, and the result is retained as key data.
