Standard Test Methods for Municipal Ferrous Scrap

SCOPE
1.1 These test methods cover various tests for assessing the usefulness of a ferrous fraction recovered from municipal wastes.  
1.2 These test methods comprise both chemical and physical tests, as follows:  Section Sampling 5 Bulk Density 6 Total Combustibles 7 Chemical Analysis (for Industries Other Than the 8 Detinning Industry) Magnetic Fraction (for the Detinning Industry) 9 Chemical Analysis for Tin (for the Detinning Industry) 10 Metallic Yield for All Industries Other Than the Copper 11 Industry and the Detinning Industry
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.
