MEASUREMENTS OF BULK DENSITY OF SOLIDS

   Test Sample 1  Test Sample 2
Sample weight (g)   4.8  5.0
 Pour Volume (V1, mL)  41  44
 Volume (V2, mL) after tap  27  27
 Pour density (g/mL)  0.12  0.11
 Mean ± SD (g/mL)     0.12 ± 0.00
 Tap density (g/mL)  0.18  0.19
 Mean ± SD (g/mL)     0.18 ± 0.01
Conclusions:
The bulk density of test substance is 0.12 g/mL for pour density, 0.18 g/mL for tap density.
Executive summary:

The density of the test substance was determined by methodology appropriate for its physical state according to CIPAC MT-159 and OECD TG 109 and ASTM D727. An appropriate amount of the test substance was weighed in order to fill 90% of a 50 mL glass cylinder. The test substance was poured into the cylinder, leveled off and the initial volume measured to the nearest 1 mL. The bottom of the cylinder was then raised 25 mm and allowed to drop until a total of 100 taps were made and a second volume measured and recorded. The pour density of the test substance is its weight divided by the initial volume, expressed in g/mL. The tap density of the test substance is obtained by dividing the weight of the test substance by the second volume (g/mL).

The bulk density of test is 0.12 g/mL for pour density, 0.18 g/mL for tap density.
