5、xidation and Alloying of Steel A846Silicon Metal A9221.2 This specification also covers a group of supplementaryrequirements which may be applied to the above specificationsas indicated therein. These are provided for use when addi-tional testing or inspection is desired and apply only whenspecified

6、 individually by the purchaser in the order.1.3 In case of conflict between the requirements of theindividual specification and this general specification, theformer shall prevail.1.4 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. Thevalues s

7、tated 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.1.4.1 This specification is expressed in both inch-poundunits and in SI units (Within the text, the

8、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.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibi

9、lity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.
