Mean density ρPR for the two test series: 1.206 g/cm3 


 


The relative density of the test item at 22.3 °C (compared with water at 4 °C) was determined to be D4R 1.21.  

Conclusions:
The relative density of the test item at 22.3 °C (compared with water at 4 °C) was determined to be D4R 1.21.
Executive summary:

A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD 109 by using the gas comparison pycnometer at ambient temperature. Two tests were performed and the density of the test item was determined. The relative density of the test item at 22.3 °C (compared with water at 4 °C) was determined to be D4R 1.21.

Description of key information

The relative density of the test item at 22.3 °C (compared with water at 4 °C) was determined to be D4R 1.21.

Key value for chemical safety assessment

Relative density at 20C:
1.21
