Density:

0.904

Temp.:

20 °C

Conclusions:

The relative density of the test material has been determined to be 0.904 at 20 °C.

Executive summary:

The determination was carried out using the pycnometer method, Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 (pycnometer)

Relative density (Specific gravity) was carried out via pycnometer method and the temperature at which the analysis was carried out was set at approximately 10°C above the maximum drop point as determined by the product specification. The water used as a reference weight during the determination was the same temperature as the product under test. 

The relative density of the test material has been determined to be 0.904 at 20 °C.

Applicant's summary and conclusion

Conclusions:

The density of the test item at 20 °C was 1.00 g/cm³ (1.00E+3 kg/m³). The relative density was 1.00.

Executive summary:

The density (ρ) and relative density of the test item were determined using a gas comparison stereopycnometer (Pycnomatic, Porotec, Frankfurt, Germany).  With this method the volume of the test item is measured in nitrogen gas (Air Products, Amsterdam, The Netherlands) in a calibrated cylinder. The test item was molten at 30 °C.  The sample cell was filled with the liquefied test item and cooled in a desiccator with silicagel as drying agent at 19.2 ± 0.0 °C for 10 minutes. The sample cell was filled with molten test item, weighed and placed in the gas comparison pycnometer.  The mean volume of the test item sample was determined (n = 4).  Thereafter the sample cell was weighed again.  The density of the test item was calculated, using sample weight before measurement and mean volume.  The test was performed in duplicate.  The mean density and relative density of the test item were calculated. Measurements were performed at 20.0 ± 0.5°C.  Weighing was performed on an analytical balance with an accuracy of 0.1 mg. The density of the test item at 20 ºC was 1.00 g/cm ³ (1.00E+3 kg/m ³).
