Key result

Type:

relative density

Density:

0.919

Temp.:

20 °C

Determination 1: 0.919 at 20 °C

Determination 2: 0.919 at 20 °C

Determination 3: 0.919 at 20 °C

Accuracy not specified.

Conclusions:

The density of the test item has been determined to be 0.919 g/m3 at 20 ± 0.5 °C.
The substance is less dense than water.

Executive summary:

The relative density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, oscillating density meter method. After calibration using two suitable reference substances, a sample was measured in triplicate at 20 °C, and the mean relative density was calculated.

The relative density of the test substance has been determined to be 0.919 at 20 ± 0.5 °C.

Description of key information

The density of the test item has been determined to be 0.919 at 20 ± 0.5 °C.

The substance is less dense than water.

Key value for chemical safety assessment

Relative density at 20C:

0.919
