- Endpoint:
- density, other
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 27 April 2017 - 28 April 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method. Test substance is adequately characterised. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)

- Deviations:
- no
- Qualifier:
- according to guideline

- density
- Density:
- ca. 0.976 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- Using the pycnometer method, a density of 0.9763 ± 0.0003 g/cm3 at 20 ± 0.4 °C was measured.
This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows good correlation of the two determinations. - Executive summary:
The study was performed in order to determine the density of test item according to OECD 109 guideline and EU A3 guideline, using the pycnometer method.
A density of 0.9763 ± 0.0003 g/cm3 at 20 ± 0.4 °C was measured.
This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows good correlation of the two determinations.

Description of key information
A density of 0.9763 ± 0.0003 g/cm3 at 20 ± 0.4 °C was measured.
This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows good correlation of the two determinations.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.976
Additional information
A fully reliable experimental study, conducted according to OECD 109 /EU A3 guideline, using pycnometer, is available. It is considered as a key study, and the result is retained as key data.
