Expiry date: November 19, 2021
Subsample 2:
Supplier: RAFFMETAL SPA
Via Malpaga 82
25070 Casto (BS), Italy
Batch No.: Rapal01 Nov 2020
Appearance: Grey solid
Storage conditions: Ambient temperature (10 °C to 30 °C)
Expiry date: December 16, 2021
Subsample 3:
Supplier: Intals SPA
Via Schievano 7
20100 Milano (MI), Italy
Batch No.: Argalum Dec 2020
Appearance: Grey solid
Storage conditions: Ambient temperature (10 °C to 30 °C)
Expiry date: January 11, 2022 - Percentile:
- D90
- Mean:
- 1 530 µm
- St. dev.:
- 21.4
- Percentile:

- Conclusions:
- The median particle size L50 of the test item deduced from the particle size distributions was 814.6 µm.
The particle size L10 of the test item deduced from the particle size distributions was 10.4 µm.
The particle size L90 of the test item deduced from the particle size distributions was 1530 µm. - Executive summary:
Winkler (2021) is a GLP-compliant study following OECD guideline 110. It is reliable without restrictions and can be used as a key study for this endpoint. Particle size distribution was determined using laser diffraction and taken into account for classification (bioavailability).
Reference
Prior to the measurement the test item was sieved with a mesh size of 1000 µm. 96.2 % (w/w) of the test item passed the sieve and only this fraction was measured with laser diffraction.
The particle size distribution of the test item Aluminium, magnesium and silicon oxides and hydroxides from refinement of aluminium salt slag residues was measured with laser diffraction. Two test series of three measurements each were performed.
The median particle size L50 (D (v, 0.5): 50 % of particle volume with lower particle diameter) deduced from these distributions were:
1st test series: L50 = 799.5 µm; 2nd test series: L50 = 829.8 µm
The average of the median particle size L50 was: L50 = 814.6 µm
The particle size L10 (D (v, 0.1): 10 % of particle volume with lower particle diameter) deduced from these distributions were:
1st test series: L10 = 10.3 µm; 2nd test series: L10 = 10.4 µm
The average of the particle size L10 was: L10 = 10.4 µm
The particle size L90 (D (v, 0.9): 90 % of particle volume with lower particle diameter) deduced from these distributions were:
1st test series: L90 = 1523 µm; 2nd test series: L90 = 1537 µm
The average of the particle size L90 was: L90 = 1530 µm
Maxima were observed at approximately 200 µm and approximately 1000 µm. Additionally, a shoulder was observed at approximately 8 µm.
