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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Principles of method if other than guideline:
- The density of the sample can be calculated based on these values - the mass of the pycnometer and water fulled in it, the mass of the pycnometer and the sample added in it and water filled in it followed, and the mass of the sample added in the pycnometer.
- GLP compliance:
- no
- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- If the sample is not fine powdery solid, it should be ground into powder: take a small amount of sample (about 0.5 mL ~ 1 mL), and put it into a mortar and then grind it, until all become fine powder. In order to prevent moisture absorption, the procedure should be carried out under an infrared lamp, or dry the sample after grinding.
- Type:
- relative density
- Density:
- ca. 5.663 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- Based on the determination results, the sample density is 5.633 g/cm3 (20°C).
