ASTM B666/B666M-96e1
(Practice)Standard Practice for Identification Marking of Aluminum and Magnesium Products
Standard Practice for Identification Marking of Aluminum and Magnesium Products
SCOPE
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 inch-pound units or SI are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the practice.
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.
