Any other information on results incl. tables
The difference between the results obtained with the Experiment 1 and Experiment 2 was > 0.02 g/cm3. Since the difference between the results obtained with the Experiment 1/Experiment 3 and Experiment 2/Experiment 3 was < 0.02 g/cm3, it was decided to calculate the density of the test item as the mean value of the three experiments.The seperate density values were 1.607, 1.582 and 1.596 g/cm3.
Applicant's summary and conclusion
- Conclusions:
- A gas comparison stereopycnometer was used for the determination of the density and relative density of the substance. The density of the test item at 20ºC was 1.60 g/cm3 and the relative density was 1.60.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
