Conclusions:
The density of the test item was calculated as 1.0642 ± 0.0003 g/cm3 at 20.0 ± 0.2°C. This value is the mean of two independent determinations with the maximum error of a single determination.
Standard deviation was 0.0004 g/cm3, showing very good correlation of the two determinations.
Executive summary:

The study was performed in order to determine the density of test item according to OECD 109, resp. EU A.3 guideline, using a pycnometer.

The density of test item was determined to be 1.0642 g/cm3 at 20°C. (relative density = 1.0642).

Description of key information

The density of test item was determined to be 1.0642 g/cm3 at 20°C.

Key value for chemical safety assessment

Relative density at 20C:
1.064

Additional information

A fully reliable experimental study, conducted according to OECD 109 /EU A3 guideline, using pycnometer, is available. It is considered as a key study, and the result is retained as key data.
