PRIMARY RESULTS OF EXPERIMENTS

Sample Preparation:

Weight of sample before drying: 8.87 g

Weight óf sample after drying: 8.28 g

Relative change: 67 %

Weight of sample for analysis I: 2.897 g

Weight of sample for analysis II: 3.678 g

Sample has been dried for 5 h at a temperature of 50 °C

Result for the volume of the test sphere (standard sphere of volume: 8.58 x 10^~6 m³):

V = 8.576 x 10^{- 6} m³

 

FINAL RESULTS

Density¹⁾= (1.76 ± 0,05) x 10³ kg/m³

The indicated error is based on an accuracy of 0.05 x 10^~6 m³ for the volume measurement. Temperature: 22 °C.

Conclusions:

The density of FAT 40400/A is 1760 kg/m³ at 22 °C.

Executive summary:

In a GLP-compliant study, performed according to EU method A.3, the density of the test substance is determined to be 1760 kg/m³ at 22 °C.
