Conclusions:
Under the conditions of the test, the density of the test substance was calculated as 1.4877 g/cm3 at 21.7°C. The relative density (compared to water at 4°C) was 1.49.
Executive summary:

A study was conducted to determine the relative density of the test substance according to OECD Guideline 109 and EU Method A.3, in compliance with GLP.

The relative density of the test substance at room temperature was measured by the air comparison pycnometer method (Micrometries MultiVolume Pycnometer 1305, Sar. No. 932). The volume of the test substance was measured with Helium in a cylinder of variable calibrated volume. Two test series with different weights were carried out in air. For the calculation of density, a mass measurement was taken after concluding the volume measurement.

Under the conditions of the test, the mean density of the test substance was calculated as 1.4877 g/cm3 at 21.7°C. The relative density (compared to water at 4°C) was 1.49.

Description of key information

The relative density of the test substance (compared to water at 4°C) was 1.49 (Smeykal, 2006).

Key value for chemical safety assessment

Relative density at 20C:
