Significance and Use
4.1 This test method for the chemical analysis of metals and alloys is primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
Scope
1.1 This test method covers the chemical analysis of magnesium ferrosilicon having chemical compositions within the following limits:
| Element | Composition Range, % |
|
| |
| Aluminum | 2.0 max |
| Calcium | 0.25 to 3.00 |
| Carbon | 0.50 max |
| Cerium | 1.0 max |
| Chromium | 0.50 max |
| Magnesium | 2.00 to 12.00 |
| Manganese | 1.0 max |
| Silicon | 40.00 to 55.00 |
| Sulfur | 0.025 max |
| Titanium | 0.2 max |
