Conclusions:
The relative density (D204) of the test item was found to be 1.41.
Executive summary:

The relative density of the test item was determined according to Regulation (EC) No 440/2008 Part A. Method A.3 and OECD Test Guideline 109. Using the pycnometer method a relative density 1.41 was measured. This value is the mean of two independent determinations.

Description of key information

The relative density (D204) of the test item was found to be 1.41 (reference 4.4-1).

Key value for chemical safety assessment

Relative density at 20C:
1.41

Additional information
