- Key result
- Type:
- relative density
- Remarks:
- D20/4
- Density:
- 0.949 other: unitless
- Temp.:
- 20 °C
- Conclusions:
- Using the pycnometer method, the density was 0.9490 ± 0.0009 g/cm3 at 20.0 ± 0.4 °C.
The test substance is less dense than water. - Executive summary:
The density of the test substance was measured according to OECD 109 / EU A3 guideline, using pycnometer method.
Two determinations were performed and the mean value was retained.
The relative density of the test item was measured as D20/4= 0.9490 ± 0.0009
