- pour density
- Density:
- 0.12 g/cm³
- Temp.:
- 20 °C
- Key result
- Type:
- tap density
- Density:
- 0.18 g/cm³
- Temp.:
- 20 °C
- 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.
