Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Experimental dates: 11 January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognized method, and under GLP. No deviation was reported. The test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- 2012
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- Regulation (EC) No. 440/2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspection 20-21 June 2017, signed on 04 September 2017
- Type of method:
- air comparison pycnometer (for solids)
- Specific details on test material used for the study:
- Storage conditions: Ambient temperature (10 °C to 30 °C) in original glass bottle.
The sample was tested as received. No further preliminary treatment such as drying or milling was performed. - Dynamic viscosity of test material:
- Not relevant (solid).
- Key result
- Type:
- relative density
- Density:
- 1.32 other: relative density has no dimension
- Temp.:
- 20.1 °C
- Conclusions:
- The substance is much more dense than water.
- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, gas comparison pycnometer method.
Two independent samples were measured ten times, and the mean density at 20.1°C was calculated to be 1.32 g/cm3. This results was then converted to relative density towards water at 4°C.
The density of the test substance at 20°C is 1.32 g/cm3, and its relative density D(20/4) is 1.32.
Reference
Two test series of ten measurements were performed on two different samples (resp. 3.5181 and 3.5614 g) at 20.1 °C. The results are summarized in table below:
Measurement |
Density roP20/ in g/cm3 (+/- SD, n=10) |
1 |
1.3193 (+/- 0.0006) |
2 |
1.3183 (+/- 0.0006) |
Mean |
1.3188 |
Description of key information
The substance is much more dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.32
Additional information
A fully reliable study, conducted according to a recognized OECD/EU method and under GLP, is available. It is considered as a key study. The result is retained as key data.
