The determination was performed in triplicate, using water with 0.1 % of sodium dodecyl sulfate as suspending medium.
In all experiments, sedimentation took place already before the first sampling time: in the three main studies, 7.0% (main study 1), 8.4% (main study 2), and 7.1 % (main study 3) of the particles were not retrieved when determining the 100% value. These particles must be considered as larger than the upper Stokes diameter of 117.54 µm.
For the measurable part of the test item charcoal (Probe 3: C-Fix = 88.7%) (particles<111.92 µm; 0.67 – 0.68% of total test item), the following particle size distribution was found (for comparison, the correlated values for the total amount of the sieved fraction (< 100µm) are also given):

Applicant's summary and conclusion
- Conclusions:
- The test item charcoal (Probe 3: C-Fix = 73.3%) shows a particle size distribution of 0.53% ≤ 117 µm and less than 0.05% (> 0.03.%) ≤ 10 µm.
