Designation: A 99 – 82 (Reapproved 2000)
Standard Specification for
Ferromanganese
This standard is issued under the fixed designation A 99; the number immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript
epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense. This specification replaces Federal Specification
QQ-F-145.
