- Key result
- Type:
- relative density
- Density:
- ca. 0.886
- Temp.:
- 20 °C
- Conclusions:
- Under consideration of the results from measurements with pycnometer it was concluded that the density of the test item was determined to be 885.9kg/m3 at 20.0 +/- 0.1°C.
The relative density of the test item was determined to be D20/4 = 0.886 - Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method.
The density of the test item was determined to be 885.9 kg/m3 at 20.0 +/- 0.1°C (mean value of two independent determinations).
The relative density of the test item was determined to be D20/4 = 0.886
Reference
Two determinations within validity criteria 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.
Results of the two determinations are reported in the following table
Table 1- Results:
| Measurement | Determination | |
| 1 | 2 | |
| Temperature (°C) | 20.0 | 20.0 |
| Mass of the empty pycnometer (m0) (g) | 31.4405 | 31.6210 |
| Mass of the pycnometer filled with ultrapure water (m2) (g) | 81.4903 | 81.6399 |
| Mass of the pycnometer filled with the test item (m1) (g) | 75.8572 | 76.0027 |
| Density of the test item (kg/m3) | 886.0 | 885.8 |
| Mean Density (kg/m3) | 885.9 | |
Description of key information
Under consideration of the results from pycnometer measurements it was concluded that tthe density of the test item was 885.9 kg/m3 at 20.0 +/- 0.1°C.
The relative density of the test item was determined to be D20/4 = 0.886
Key value for chemical safety assessment
- Relative density at 20C:
- 0.886
Additional information
A fully reliable experimental study, conducted according to the recognized OECD 109 / EU A.3 methods and under GLP, is available.
It is considered as a key study, and the result is retained as key data.
