1、Designation: B 666/B 666M 01Standard 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 (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.1. Scope*1.1 This practice establishes the phys
3、ical 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 inch-pound units or SI are tobe regarded separately as standard. The SI units a
4、re shown inbrackets. The values stated in each system are not exactequivalents; therefore, each system must be used indepen-dently of the other. Combining values from the two systemswill result in nonconformance with the practice.1.3 This standard does not purport to address all of thesafety concern
5、s, if any, associated with its 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.

Basic Marking Requirements and Application4.1 When required by the material specification or specifiedin the contract or purchase order, wrought aluminum andmagnesium mill
24、 products shall be marked for identificationpurposes only with the following information on the product oron tags attached to the product:4.1.1 Name or Registered Trademark of the Company,which performs the final processing or finishing operation suchas rolling, stretching, thermal treatment, etc.,
25、prior to market-ing the product;NOTE 1The company that performs nothing more than a simpleshearing or sawing operation may be excluded from marking the productwith its name.4.1.2 Alloy and Temper of the ProductDesignations shallbe in accordance with ANSI H35.1 H35.1M for aluminumand MIL-STD-409 for
