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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:

- Type:
- relative density
- Density:
- 1.525
- Temp.:
- 20 °C
- Conclusions:
- Relative density: 1.5251 at 20 °C.
- Executive summary:
Relative density was determined by means of a pycnometer as per recommendations of OECD guideline 109 and EU method A3. A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The density of the test item was calculated from its weight and volume.
The relative density resulted 1.5251, at 20 °C.
Conclusion
Relative density: 1.5251, at 20 °C.
Reference
Results of the measurement of the density of the test item
| Test No. | Temperature [°C] | Amount of test item [g] | Average sample volume [cm³] | Density [g/cm³]* |
| 1 | 20 | 11.09 | 7.26643 | 1.52620 |
| 2 | 20 | 11.23 | 7.36909 | 1.52393 |
* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.
The mean density of the test item at 20 °C is 1.5251 g/cm³.The relative density D420 is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).
Description of key information
