- Type:
- relative density
- Density:
- 1.519
- Temp.:
- 20 °C
Applicant's summary and conclusion
- Conclusions:
- Relative density was determined at 1.519 at 20 °C using the pycnometer method.
- Executive summary:
The relative density (D4/20) of solids is a ratio between the mass of a volume of substance to be examined, determined at 20 °C, and the mass of the same volume of water at 4 °C. The relative density has no dimension.
The relative density of the substance was deteremined at 1.519.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
