Description of key information
The relative density of manganese ores, reduced was determined (using EU method A3) to be 4.22 at a temperature of 23 °C
Key value for chemical safety assessment
- Relative density at 20C:
- 4.22
Additional information
The relative density of the test material was investigated in a study which was conducted in accordance with the standardised guideline EU Method A.3. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of the study the relative density of the test material was determined to be 4.22 at a temperature of 23 ± 0.5 °C.
