- Key result
- Type:
- relative density
- Density:
- 1.53 other: dimensionless
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 1.53 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density was1.53E+03 kg/m3 (equivalent to 1.53 g/cm3) at 20.0 ± 0.5 ºC.
- Executive summary:
The study was performed according to the OECD Guideline 109 and EC Method A.3 and in compliamce with GLP for determing the density of the test substance. The relative density of the test substance has been determined to be 1.53 at 20.0 ± 0.5 ºC.
Reference
CALIBRATION
The pressure readings and the calculated volume for the reference and sample cells are shown in Table 1. As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3 and 149.225 ± 1.0 cm3 for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.
SAMPLE
The pressure readings, calculated volumes and density values obtained for the test item are shown in Table 2.

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.
