Results and discussion
Density
- Type:
- relative density
- Density:
- ca. 4.71 - ca. 5.57 g/cm³
- Temp.:
- 20 °C
- Remarks on result:
- other: from 2 representative samples
Applicant's summary and conclusion
- Conclusions:
- Good quality study that provides an indicative value of the relative density for copper scale, measured on representative samples
- Executive summary:
Relative density far copper scale is ca. 4 g/m3. For two representative Copper scales, measured values varied between 4.71 and 5.57 g/m3. It has to be noted that the UVCB is characterized by large variety in the structures of the material and density mentioned is therefore only indicative.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
