The results from the duplicate determinations showed reproducibility of less than ± 20 kg/m3; therefore, the results were considered acceptable.

Executive summary:

The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, gas comparison pycnometer method. After triplicate calibration, two independant samples were measured in triplicate, and the mean density at 20°C was calculated to be 1052 kg/m3. This results was then converted to relative density towards water at 4°C.

The density of the test substance at 20°C is 1052 kg/m3, and its relative density D(20/4) is 1.052.

Description of key information

The density of the test substance at 20°C is 1052 kg/m3, and its relative density D(20/4) is 1.052.

Key value for chemical safety assessment

Relative density at 20C:
1.052

Additional information

A fully reliable study, conducted according to a recognized OECD/EU method and under GLP, is available. It is considered as a key study. The result is retained as key data for purpose of CSA.
