Historical (view previous versions of standard)
This practice establishes the requirements for physical item identification marking of aluminum and magnesium products. Package marking for shipment and inspection acceptance is not within the scope of this standard. Wrought aluminum and magnesium mill products shall be marked for identification purposes only with the following information on the product or on tags attached to the product: (1) name or registered trademark of the company, (2) alloy and temper of the product, (3) basic number of the specification to which the product was produced, (4) specified (ordered) dimensions of the following products: sheet and plate, coiled wire and spooled wire, straight length tube and coiled tube, and pipe, (5) lot number, and (6) the word "seamless" on certain tube or pipe. Spot marking requirements for the following wrought aluminum and magnesium mill products are detailed and illustrated: (1) coiled sheet, (2) flat sheet and plate, (3) circles, (4) tread plate, (5) foil, (6) rod, bar, and extruded profiles, (7) structural profiles, (8) tube and pipe, (9) wire, (10) bus bar, and (11) forgings such as hand and die forgings. Requirements for marking cast aluminum and magnesium products (castings, remelt ingot for castings, and ingot or billet for fabricating), unalloyed aluminum and magnesium ingot, and special products are specified.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This practice establishes the physical item marking requirements for identification purposes for aluminum and magnesium products. 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 standard. The values 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.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
