The results of the tests on the determination of the density of the test item are given as below.

The individual measurements were obtained with an accuracy of < 0.02 g/cm³. According to the guideline, the density of the test item is given as the mean value.

Density of the Test Item

	Test 1	Test 2	Mean
Density [g/cm^3]	1.397	1.397	1.40

Conclusions:

The density of the test item at 20ºC was 1.40 g/cm3 (1.40E+03 kg/m3).
The relative density was 1.40.

Executive summary:

A gas comparison stereopycnometer was used for the determination of the density and relative density of the test item.

The density of the test item at 20ºC was 1.40 g/cm3(1.40E+03 kg/m3).

The relative density was 1.40.
