Executive summary:

Method

The substance has been tested for density according to the OECD Guideline 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.

Result

The substance shows a relative density of 1.780, at °C.

Description of key information

Relative density: 1.780 at 20 °C

Key value for chemical safety assessment

Relative density at 20C:
1.78

Additional information

Relative density was determined by means of a pycnometer as recommendations of OECD 109 Guideline.
