1.1This specification covers a group of common requirements that, unless otherwise specified in an individual specification, shall apply to ferroalloys and other alloying materials under each of the following ASTM specifications:
| Title of Specification | ASTM Designation |
| Ferromanganese | A99 |
| Ferrosilicon | A100 |
| Ferrochromium | A101 |
| Ferrovanadium | A102 |
| Ferromolybdenum | A132 |
| Molybdenum Oxide Products | A146 |
| Ferroboron | A323 |
| Ferrotitanium | A324 |
| Chromium Metal | A481 |
| Ferrochrome-Silicon | A482 |
| Silicomanganese | A483 |
| Calcium-Silicon Alloys | A495 |
| Ferrocolumbium | A550 |
| Electrolytic Manganese Metal | A601 |
| Nickel Oxide Sinter | A636 |
| Ferromanganese Silicon | A701 |
| Titanium Scrap for Use in Deoxidation and Alloying of Steel | A845 |
| Aluminum Scrap for Use in Deoxidation and Alloying of Steel | A846 |
| Silicon Metal | A922 |
1.2This specification also covers a group of supplementary requirements which may be applied to the above specifications as indicated therein. These are provided for use when additional testing or inspection is desired and apply only when specified individually by the purchaser in the order.
1.3In case of conflict between the requirements of the individual specification and this general specification, the former shall prevail.
1.4Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4.1This specification is expressed in both inch-pound units and in SI units (Within the text, the SI units are shown in brackets); however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
