2、arentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers grades of silicomanganese.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately
3、as standard.Thevalues 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.1.2.1 This specification is expressed in both inch-poundunits and in SI units(
4、within the text,the SI units are shown inbrackets);however,unless the purchase order or contractspecifies the applicable M specification designation(SI units),the inch-pound units shall apply.2.Referenced Documents2.1 ASTM Standards:2A1025 Specification for Ferroalloys and Other AlloyingMaterials,Ge
