Conclusions:
Under the conditions of the study, the average density of the test substance was determined to be 0.94 g/cm3 at 20ºC. The relative density was 940.

Executive summary:

The density was determined according to Method NF T20 – 053 (determination of density of solids in powder and liquids). The determination was carried out with a pycnometer using the displacement method and hexadecane as solvent, in duplicate. Under the conditions of the study, the average density of the test substance was determined to be 0.94 g/cm3 at 20 ºC and the relative density was 940.

Description of key information

 The density was determined according to Method NF T20 – 053 (determination of density of solids in powder and liquids) (Börjesson, 2012).

Key value for chemical safety assessment

Relative density at 20C:
