Type:
relative density
Density:
0.893 other: relative density has no dimension
Temp.:
21.3 °C

Two test series with different weights were performed at ambient temperature (21.3 °C).

1strun:

- 1. measurement 0.8941 g/cm3

- 2. measurement 0.8947 g/cm3

- 3. measurement 0.8926 g/cm3

mean: 0.8938 g/cm3

2ndrun:

- 1. measurement 0.8929 g/cm3

- 2. measurement 0.8931 g/cm3

- 3. measurement 0.8928 g/cm3

mean: 0.8930 g/cm3

mean density for the two test series: 0.893 g/cm3

relative density (compared to water at 4 °C): 0.893

Conclusions:
The relative density at an ambient temperature of 21.3 °C (compared to water at 4°C) is 0.893.
Executive summary:

The relative density of the sample was tested according to EU Method A.3 and OECD Guideline 109 in a non-GLP study with a gas comparison pycnometer. The relative density at an ambient temperature of 21.3 °C (compared to water at 4°C) is 0.893.

Description of key information

The relative density of the sample was tested according to EU Method A.3 and OECD Guideline 109 in a non-GLP study with a gas comparison pycnometer. The relative density at an ambient temperature of 21.3 °C (compared to water at 4°C) is 0.893.

Key value for chemical safety assessment

Relative density at 20C:
0.893

Additional information

Key value for the risk assessment was not measured at an ambient temperature 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.
