Results and discussion
Density
- Type:
- relative density
- Density:
- 3.48
- Temp.:
- 21.4 °C
- Remarks on result:
- other: Weight of test substance: 17.6911 g. Relative density obtained across 5 samples was in the range 3.4779 to 3.4829.
Applicant's summary and conclusion
- Conclusions:
- The relative density of basic copper carbonate was between 3.4779 — 3.4829 at 21.4 °C.
- Executive summary:
Actual measurement temperature was 21°C and not 20°C, however, it is considered this makes no significant difference to the result as the change in density with temperature for most solids is negligible over a few degrees range. Therefore, any inaccuracy may be expected to be within overall experimental error.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
