- November 29, 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:

- Type:
- density
- Density:
- ca. 1.044 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The average of calculated relative density at 20°C temperature was 1.044.
- Executive summary:
In accordance with OECD guideline EEC Method A3 and GLP study, the relative density was measured using Gay-Lussac pycnometer at temperature 20ºC. The density was calculated by dividing the mass of tested substance by its volume (pycnometer volume).Two measurement was carried out as the difference between result was less than 0.03 g/ml. The average of relative density at temperature 20ºC was 1.044 and of absolute density was 1.044 g/ml.
