- Type of method:
- air comparison pycnometer (for solids)
- Type:
- relative density
- Density:
- 1.26 other: relative denisty has no dimension
- Temp.:
- 22.8 °C
- Conclusions:
- The relative density at an ambient temperature of 22.8 °C (compared to water at 4°C) is 1.26.
- Executive summary:
The relative density of the test item was determined according to OECD Guideline 109, EU Method A.3 and DIN 66137 -2 with a gas comparison pycnometer. The relative density at an ambient temperature of 22.8 °C (compared to water at 4°C) is 1.26.
Reference
Two test series with different weights were performed at ambient temperature (22.8 °C).
1st run:
- 1. measurement 1.2638 g/cm3
- 2. measurement 1.2645 g/cm3
- 3. measurement 1.2629 g/cm3
mean: 1.2636 g/cm3
2nd run:
- 1. measurement 1.2635 g/cm3
- 2. measurement 1.2614 g/cm3
- 3. measurement 1.2593 g/cm3
mean: 1.2614 g/cm3
mean density for the two test series: 1.263 g/cm3
relative density (compared to water at 4 °C): 1.263
Description of key information
The relative density of the test item was determined according to OECD Guideline 109, EU Method A.3 and DIN 66137 -2 with a gas comparison pycnometer. The relative density at an ambient temperature of 22.8 °C (compared to water at 4°C) is 1.26.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.26
Additional information
Key value for the risk assessment was not measured at an ambient temparature of 20 °C. Ambient temperature was determined to be 22.8 °C. Nevertheless this difference can be disregarded due to only minor changes in the respective key value for chemical safety assessment.
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.
