- Key result
- Type:
- relative density
- Density:
- ca. 1.13
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the sample at 20 ± 1 oC was found to be 1.13 ± 0.07 relative to water at 4 oC.
- Executive summary:
Dried waste sludge from a biological civic effluent treatment utility was examined to ascertain its Relative Density, according to the method A.3 described at the Council Regulations (EC), No. 440/2008, Published in O.J.L 142, 2008.
The relative density of the sample was determined by the use of a pycnometric method at 20 ± 1 oC and found to be 1.13 ± 0.07.
Reference
The relative density of the sample at 20 ± 1 oC for the three measurements was found to be 1.123, 1.131 and 1.137 giving an average of relative density of the substance of 1.13 ± 0.07 relative to water at 4 oC.

Additional information
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.
