- Stability under storage conditions: stability - Remarks on result:
- other:
- Remarks:
- The mass of the sample particles over 2000μm accounts for 98.17% of the total, and it is not applicable for the instrument.
- Key result
- Percentile:
- other: D98.17
- Mean:
- >= 2 000 µm
- Remarks on result:
- other: The mass of the sample particles over 2000μm accounts for 98.17% of the total, and it is not applicable for the instrument.
