Standard Test Method for
Wetting and Drying Test of Solid Wastes1

This standard is issued under the fixed designation D 4843; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

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 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.

2. Referenced Documents

2.1 ASTM Standards: 2
C 305 Practice for Mechanical Mixing of Hydraulic Cement
Pastes and Mortars of Plastic Consistency
D 2216 Test Method for Laboratory Determination of Water
(Moisture) Content of Soil and Rock

3. Significance and Use

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

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 and/or comparison of mass loss-cycle relations of
different wastes, as well as to measure the method-related mass
losses such as matrix dissolution.
