【国外标准】 Standard Test Method for Wetting and Drying Test of Solid Wastes

3.1 This test method is intended for the evaluation of the wetting and drying resistance of monolithic, solid, solidified/stabilized wastes under the testing conditions of this test method. 3.2 This test method may be used for the comparison of wetting and drying resistance of wastes. 3.3 Data tabulated in Table 1, Table 2, and Table 3 may be used to observe irregularities caused by inhomogeneity of specimens, or comparison of mass loss-cycle relations of different wastes, or both, as well as to measure method-related mass losses such as matrix dissolution. 1.1 This test method covers procedures for determining material losses produced by repeated wetting and drying 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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
