Relative density D20/4:

Experiment 1: 0.9795

Experiment 2: 0.9789

Mean: 0.979

Conclusions:
Under the study conditions, the mean relative density value of the test substance was established at 0.979.
Executive summary:

A study was conducted to determine the relative density of the test substance according to OECD Guideline 109, EU Method A.3 and OPPTS 830.7300. The relative density of the substance was determined in duplicate at 20°C using a gas comparison pycnometer. Under the study conditions, the mean relative density value of the test substance was established at 0.979 (Reingruber, 2017).

Description of key information

The relative density was determined according to OECD Guideline 109, EU Method A.3 and OPPTS 830.7300 (Reingruber, 2017).

Key value for chemical safety assessment

Relative density at 20C:
0.979
