1、Designation: B 666/B 666M 08Standard Practice forIdentification Marking of Aluminum and MagnesiumProducts1This standard is issued under the fixed designation B 666/B 666M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of
2、 last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This practice establishes the physi
3、cal item markingrequirements for identification purposes for aluminum andmagnesium products. Package marking for shipment andinspection acceptance is not within the scope of this standard.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The value
4、s stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with it
5、s use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
