Specification for Municipal Aluminum Scrap (MAS) (Withdrawn 2001)

SCOPE
1.1 This specification covers municipal-refuse originated aluminum alloy scrap (MAS), not source-separated, that is recovered from industrial, commercial, or household wastes destined for disposal facilities.  
1.2 Municipal aluminum scrap (MAS) covered by this specification is suitable for use by the following industries:  
1.2.1 Secondary aluminum smelters,  
1.2.2 Primary aluminum producers,  
1.2.3 Aluminum scrap dealers,  
1.2.4 Iron and steel industry,  
1.2.5 Foundries,  
1.2.6 Nonintegrated aluminum producers, and  
1.2.7 Independent aluminum fabricators.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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. The hazard statement applies only to the test method sections in the annexes of this specification.
