The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be 1.04.

Conclusions:
The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be 1.04.
Executive summary:

A study was performed in accordance EU method A.3 by using the gas comparison pycnometer at 20.0°C. Two tests were performed and the density of the test item was determined. The relative density of the test item was determined to be 1.04.

Description of key information

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be 1.04.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

A study was performed in accordance with method A.3 using the gas comparison pycnometer at 20 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item (calculated from the mean density of the test item) was determined to be D420= 1.04.
