- Density:
- 0.949 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density of the test item was determined to be 0.9490 ± 0.0002 g/mL at 20.0 ± 0.2 °C,
- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of the test item. Using the pycnometer method the density was determined in two independent trials to be 0.949 ± 0.0001 g/mL at 20 ± 0.2 °C. The relative density of the test item was determined to be 0.949 respectively. The standard deviation reflects the distinguished correlation of the two determinations and fulfils the requirements of the respective guidelines. No observations were made which cause any doubt on the outcome of this study. Therefore, the study was considered valid.
