- Conclusions:
- A range of 2000 to 1000 µm covers 90 % of the particle size distribution of TODI. No particles with a diameter below 63 µm were found.
- Executive summary:
After determination of the tap density (0.75 g/mL), the particle size distribution of TODI was found to be [1000 µm; 2000 µm] applying machine sieving, specified by the range [x1, x2] of two sieves where Rx1 >= 90% and Rx2 <= 10%.
Seven sieves of sizes (µm) 63, 125, 250, 500, 1000, 2000 and 4000 were used.
Reference
The tap density (CIPAC MT 169) of TODI was found to be 0.75 g/mL.
The mass of the sample needed for the main test (m) was calculated to 105.5 g.
The particle size distribution of the test item was specified by the range [x1, x2] of two sieves where Rx1 >= 90% and Rx2 <= 10%.
Description of key information
