ASTM D4842-90(2001)

Standard Test Method for Determining the Resistance of Solid Wastes to Freezing and Thawing (Withdrawn 2006)

SCOPE
1.1 This test method covers procedures for determining material losses produced by repeated freezing and thawing of solid waste specimens. It also covers the visual observation of the disintegration of solid specimens.
1.2 This test method intends that the material used in the procedure be physically, chemically, and biologically representative, hence it does not address problems as a result of the inhomogeneity of specimens.
1.3  This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
WITHDRAWN RATIONALE
This test method covers procedures for determining material losses produced by repeated freezing and thawing of solid waste specimens. It also covers the visual observation of the disintegration of solid specimens.
This test method is being withdrawn because there is not the expertise currently to determine correct sample preparation methods for D 4842.
Formerly under the jurisdiction of Committee D34 on Waste Management, this test method was withdrawn in October 2006.
