The relative density of the test item was calculated as 0.9209±0.0001 at 20.00± 0.05°C, which is the mean of two values ± the standard deviation.

Discussion

No deviations from the guideline were stated. The two determinations show minimal variations. Additional measurements will not be performed for confirmatory purposes. Therefore, both determinations apply according the guidelines used.

This equipment is designed for Flavors and Fragrances among others.

Comprehensive test functions ensure the instruments always provide exact results:

• cell test function. Automatic insufficient cleaning detection.

• scheduled tests. The key to sustainable accuracy.

• full range correction of errors caused by the sample’s viscosity.

Conclusions:
The mean relative density of the test item was D20/20 = 0,9209 ± 0,0001.
Less dense than water.
Executive summary:

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

The relative density of the test item was measured as D20/20= 0,9209 ± 0,0001.

Description of key information

The mean relative density of the test item was D20/20 = 0,9209 ± 0,0001.

The test substance is less dense than water.

Key value for chemical safety assessment

Relative density at 20C:
0.921

Additional information

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