Remarks on result:
other: D20/4

The density of a liquid was measured with the oscillating densitometer at 20'C. Two tests were performed at 20.0 'C. The results are summarised in Table 1.

Table l: Results of the two tests

Measurement

Density ρP20, g/cm3

1

0.9198

2

0.9198

Mean

0.9198

Mean density ρP20for the tow tests: 0.9198 g/cm3

Relative density (compared to water at 4 °C, ρW4) D20/4

D20/4 = ρP20/ ρW4= 0.92

Conclusions:
The mean relative density of the test item was determined as D20/4 = 0,92
Executive summary:

The density of the test substance was measured according to OECD 109 / EU A3 guideline, using oscillating densitometer. After calibration two measurements were performed and the mean value was retained.

The relative density of the test item was determined as D20/4= 0.92.

Description of key information

The relative density of the test item was measured as D20/4= 0,92

Key value for chemical safety assessment

Relative density at 20C:
0.92

Additional information

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