1、Designation: B666/B666M 08B666/B666M 15Standard Practice forIdentification Marking of Aluminum and MagnesiumProducts1This standard is issued under the fixed designation B666/B666M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, th
2、e year of 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 U.S. Department of Defense.1. Scope*1.1 This practice establi
3、shes the physical item marking requirements for identification purposes for aluminum and magnesiumproducts. Package marking for shipment and inspection acceptance is not within the scope of this standard.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as st
4、andard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 This standard does not purport to address all of the safety concerns, if any
5、, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

Basic Marking Requirements and Application4.1 When this practice is required by the material specification or specified in the contract or purchase order, wrought aluminumand magnes
17、ium mill products shall be marked for identification purposes 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 such as rolling,stretching, thermal treatme
18、nt, etc., prior to marketing the product;NOTE 1The company that performs nothing more than a simple shearing or sawing operation may be excluded from marking the product with itsname.4.1.2 Alloy and Temper of the ProductDesignations shall be in accordance with ANSI H35.1/H35.1M for aluminum andMIL-S
19、TD-409 for magnesium;4.1.3 Basic Number of the Specification to which the Product was ProducedThe basic number does not include the revisionindicator;4.1.4 Specified (Ordered) Dimensions of the Following Products:4.1.4.1 Sheet and PlateThickness in inches millimetres,4.1.4.2 Coiled Wire and Spooled
20、WireDiameter in inches millimetres,4.1.4.3 Tube:(1) Straight LengthsOutside diameter and wall thickness, in inches millimetres,(2) CoiledWall thickness, in inches millimetres,4.1.4.4 PipeNominal pipe size and ANSI schedule number;4.1.5 Lot number shall be included in the product marking. The definit
21、ion of lot shall be that as defined in the materialspecification.4.1.6 For magnesium products, the applicable lot number shall be marked on each piece in at least one location.4.1.7 When required by the material specification, the word “seamless” on certain tube or pipe.NOTE 2The requirements specif
22、ied in 4.1 are minimum; marking systems that involve additional information shall be as agreed upon between theproducer and the purchaser.4.2 When this practice is required by the material specification or specified in the contract or purchase order, marking of castaluminum products shall be in acco
23、rdance with Section 6.4.3 Product marking shall be such that it shall not rub off or be otherwise obliterated by contact arising from normal handling,exposure to the elements, shipment, and storage. The height of the characters shall be commensurate with the size of the productbeing marked; for exam
24、ple, not less than 0.375 in. 9 mm for flat sheet and plate, not less than 0.250 in. 6 mm for hand forgingsand not less than 0.125 in. 3 mm for tubular products. Legibility of all markings shall be such as required for ready readabilityand the required permanency of identification.4.4 Product marking
25、 shall be accomplished in a manner that will not adversely affect the subsequent fabrication of the material,or produce stresses that would be deleterious to the functioning of the finished product. Marking on the product shall be withmarking fluid applied by printing, stamping, or stenciling. Ghost
26、 images of the characters may remain upon the removal of markingapplied. Impression stamping is considered detrimental and shall not be used except on ingot, castings, forging, and certain tubeproducts, or when required by prior agreement between the producer and purchaser.5.
