Conclusions:
The density of the reaction product was determined according to the French Norm NF T 20-050. The result can be expressed as follows:
density = 1.070 +/- 0.001 g/cm3.
Executive summary:

The study was performed in order to determine the density of test item according to Norm NF T 20-050.

The density of test item was determined to be 1.07 g/cm3 (relative density: 1.07).

Description of key information

The density of the reaction product was determined according to the French Norm NF T 20-050. The result can be expressed as follows:

p = 1.070 +/- 0.001 g/cm3.

Key value for chemical safety assessment

Relative density at 20C:
