Executive summary:

The determination was carried out using the pycnometer method, designed to be compatible with Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012.

 

Conclusion

The density of the test item has been determined to be 783 kg/m3 at 20.0 ± 0.5°C, relative density 0.783.

Description of key information

The relative density of the substance at 20± 0.5°C was 0.783.

Key value for chemical safety assessment

Relative density at 20C:
0.783

Additional information

A measured relative density value of 0.783 at 20 ± 0.5°C (density = 783 kg/m3 at 20 ± 0.5°C) was determined for the substance using the pycnometer method in accordance with OECD 109 and in compliance with GLP. The result is considered to be reliable.
