- Density (g/mL):
Pour density 0.436
Tap density 0.577 - Executive summary:
The density of the test substance was determined by methodology appropriate for its physical state according to OPPTS.830.7300, ASTM D 727, CIPAC MT-159 and OECD TG 109.
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).
Pour density was measured as 0.436 g/mL
Tap density was measured as 0.577 g/mL
