    Significance and Use

    This classification is intended for use in the marketing of mixed nonferrous metals.

    Mixed nonferrous metals covered by this classification are suitable for use by one or more of the following industries:

    Secondary aluminum smelters,

    Primary aluminum producers,

    Scrap dealers and processors,

    Zinc refiners, and

    Copper refiners.

    1. Scope

    1.1 This classification covers municipal mixed nonferrous metals (MNM), not source-separated, that are recovered from municipal waste destined for disposal.

    1.2 The mixed nonferrous metals (MNM) have been sub-
    divided according to processing history, nonferrous metal content, size, and moisture content.

    1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    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.

    A1.1.1 This test method describes procedures for collection of a sample of MNM scrap recovered from municipal refuse, and the preparation and secondary sampling of the metal for analysis.
