Any other information on results incl. tables

A reference cell of a defined volume (Vref) was pressurized with helium to a pressure of not more than 20 psi (137.9 kPa) and the pressure was read. Subsequently, the volume of the sample cell (being filled with helium at ambient pressure) was added to the pressure system, resulting in a lower pressure, which was also read. During the performance of the test, the temperature was controlled and kept constant.

 

The sample cell was weighed, filled with the test item and placed in the Multi-Pycnometer. Then, the test was performed as outlined above, resulting in pressure readings p1(sample)and p2(sample)for the upper and the lower pressure readings, respectively. From these pressure readings, the volume of the test item was calculated. The procedure was repeated until reproducible results were obtained (repeatability of < ± 0.02 g/cm³). The sample cell containing the test item was reweighed to determine the mass of the tested material.

Applicant's summary and conclusion

Conclusions:

The density of the test item FAT 40842/A TE was determined to be 1.305 g/cm³ (= 1.305 · 10³ kg/m³) at 20.0 °C ± 0.1 °C

The relative density of FAT 40842/A TE was determined to be D(20/4) = 1.305

Executive summary:

The purpose of the study was to determine the relative density of the test item at a specific temperature by means of a gas comparison pycnometer. The density of the test item FAT 40842/A TE was determined to be 1.305 g/cm³ (= 1.305 · 10³ kg/m³) at 20.0 °C ± 0.1 °C using a gas comparison pycnometer. The relative density of FAT 40842/A TE was determined to be D(20/4) = 1.305.
