Measurement 1       1.3307 g/cm3

Measurement 2       1.3306 g/cm3

Measurement 3       1.3303 g/cm3

Measurement 4       1.3303 g/cm3

Measurement 5       1.3307 g/cm3

The mean density out of the five measurements was calculated to be 1.3305 g/cm3.

The relative density was calculated by division with the factor 1.0000 g/cm3.

As a result the relative density of the test item was determined to be 1.331 +/- 0.0002.

Conclusions:
Based on the results of this study, the relative density of the test item was determined to be 1.331.
Executive summary:

A study was conducted according to guideline 92/69/EWG A.3 in order to determine the relative density of the test item. The pycnometer method was applied and five independent measurements were performed. Based on the results of this study relative densitiy of the test item was determined to be 1.331.

Description of key information
