The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.17.

Conclusions:
The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.17.
Executive summary:

A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 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 D4R 1.17.

Description of key information

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.17.
