Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 17 March to 18 April 2017
- 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. Test substance is adequately specified with purity. 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
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP compliance programme (inspected on 05 July 2016 / signed on 28 October 2016)
- Type of method:
- pycnometer method

- Density:
- 925.2 kg/m³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 0.925 other: unitless
- Temp.:
- 20 °C
- Conclusions:
- The substance is less dense than water.
- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method. Two runs were performed, and the mean density at 20.0 °C was calculated. This result was then converted to relative density towards water at 4 °C.
Mean density: 925.2 kg/m3
Mean relative density: 0.925
Test item temperature: 20.0 ± 0.5 °C
The density of the test item has been determined to be 925.2 kg/m3 at 20.0 ± 0.5 °C and a relative density (D20/4) of 0.925.
