- Temp.:
- 20 °C
- Type:
- density
- Density:
- 1.125 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test substance was determined to be 1.125 at 20 °C.
- Executive summary:
A study was conducted according Regulation (EC) No 92/69/EWG method A.3 to determine the relative density of the test item. The density was measured using the gas comparison pycnometer method. The measurement cycle consisted of five individual measurements. The mean density of the test item was 1.1247 g/cm³. The relative density was calculated by dividing the density of the test item by the factor 1.0000 g/cm³. The relative density of the test item was determined to be 1.125 at 20°C.
Reference
The measurement cycle consisted of five individual measurements.
Table 1: Results of the measurements
Measurement | Density / g/cm3 |
1 | 1.1247 |
2 | 1.1248 |
3 | 1.1246 |
4 | 1.1247 |
5 | 1.1246 |
Mean density for the five measurements: 1.1247 g/cm3
Relative density: 1.125 g/cm3 / 1.0000 g/cm3 = 1.125 ± 0.0001
Description of key information
The relative density of the test substance was determined to be 1.125 at 20 °C (reference 4.4-1).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.125
