Reference
Table: Determining the Density of the Test Item
| Run Number | 1 | 2 |
| Mass of Empty Pycnometer (g) | 24.07 | 24.21 |
| Mass of Test Item & Pycnometer (g) | 35.54 | 35.75 |
| Mass of Test Item added to empty Pycnometer (g) | 11.47 | 11.53 |
| Mass of Test Item, Pycnometer & immersion liquid | 48.83 | 49.37 |
| Mass of immersion liquid added (g) | 13.28 | 13.62 |
| Calculated Density of Test Item (g.cm-3) | 0.996 | 0.993 |
| Density of Test Item (kg.m-3) | 996 | 993 |
| Mean Result (kg.m-3) | 995 | |
Due to the viscous nature of the test item it was degassed for one hour. It was then allowed to stand for over 48 hours before being degassed for a further 2 hours. After allowing the test item to cool, it was weighed; the immersion liquid was added and then reweighed.
Description of key information
The relative density of the substance was determined using the pycnometer method in a GLP study according to OECD guideline 109 and EU Method A.3 (K1, Dekra, 2018) and was found to be 0.995.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.995
Additional information
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.
