Results and discussion
Density
- Type:
- relative density
- Density:
- 1.65
- Temp.:
- 20 °C
- Remarks on result:
- other: Standard deviation: 0.0030 g/cm3 Relative standard deviation: 0.18 %
Any other information on results incl. tables
Two test series with different weights of the test item (Experiment 1: 1.4330 g, Experiment 2: 1.4348 g), technical substance, a yellow solidified melt, were carried out in helium gas at 20 °C. To ensure the complete purging and thermal equilibration of the system, the first twenty measurements of each experiment were excluded from the evaluation. For averaging, only the results of the last ten measurements were used.
Mean density ρP20 for the measurements: 1.65 g/cm3
Standard deviation: 0.0030 g/cm3
Relative standard deviation: 0.18 %
Relative density (compared to water at 4 °C) D420 :
D420 = ρP20 / ρW4 = (1.65 g/cm3)/(1.00 g/cm3) = 1.65
Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
