- 20 °C
Applicant's summary and conclusion
- Conclusions:
- The tap density of the test item was determined to be = 0.4 g/cm3.
- Executive summary:
The tap density of the test item was determined as below.
A 100ml measuring cylinder was placed on a top pan balance, sample was added until the volume was 100ml. The weight of sample was 29.56g.
The measuring cylinder was then tapped 50 times. The volume after this was 74ml.
Tap density = 0.4 g/cm3
