ISO 12103-1,A2 Fine Test Dust is nominal 0-80 micron size. ISO Fine Dust is identical to SAE Fine Test Dust produced by Powder Technology Inc. prior to formation of this Standard. The basis for acceptable particle size limits specified per ISO 12103-1, A2 were derived from analysis of eight batches of SAE Fine Test Dust manufactured by Powder Technology, Inc. between 1992 and 1994. A view of volume differential particle size data indicates a bi-modal distribution with approximate peaks at 4 and 20 micron size. The bi-modal aspect of this product traces back to the original roller analysis specification of Fine Test Dust shown in former revisions of SAE J726 Specification.
3. Chemical composition (expressed as % by mass of oxides)
These components were determined through typical chemical analysis of Arizona desert sand:
| Chemical composition | Symbol | Percentage (% by weight) |
|---|---|---|
| Silicon Dioxide |
SiO₂ |
69,0% – 77,0% |
| Aluminum Oxide |
Al₂O₃ |
8,0% – 14,0% |
| Iron Oxide |
Fe₂O₃ |
4,0% – 7,0% |
| Potassium Oxide |
K₂O |
2,0% – 5,0% |
| Calcium Oxide |
High |
2,5% – 5,5% |
| Sodium Oxide |
Na₂O |
1,0% – 4,0% |
| Magnesium Oxide |
MgO |
1,0% – 2,0% |
| Titanium Dioxide |
TiO₂ |
0,0% – 1,0% |
SiO₂4. Important physical properties
- Main material: Quartz.
- Hardness: 7.0 (on the Mohs scale).
- Substance density: Approximately 2.65 g/cm³.
- Bulk density: Approximately 0.90 g/cm³ (900 kg/m³)
