Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Two tests with different pycnometers were carried out at a temperature of 20 °C.
| Pycnometers | Dimension | 58 | 76 |
| Volume | cm3 | 49.820 | 50.000 |
| Weight of empty pycnometer | g | 36.7238 | 38.3214 |
| Weight of pycnometer filled with water | g | 86.3647 | 88.1564 |
| Weight of water | g | 49.6409 | 49.8350 |
| Weight of emtpy pycnometer | g | 36.7231 | 38.3211 |
| Weight of the pycnometer filled with test item | g | 87.9657 | 89.7750 |
| Weight of test item | g | 51.2426 | 51.4539 |
| Relative density at 20 °C D2020 | - | 1.0323 | 1.0325 |
Mean relative denstiy at 20 °C D2020 = 1.0324
The relative density (compared to water at 4 °C) of the test item is:
D420 = D2020 x 0.998 = 1.0324 x 0.998 = 1.030
Description of key information
1.03 at 20°C (compared to water at 4°C)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.03
