Scope

1.1 This test method provides a procedure for obtaining the data which are used to calculate the shrinkage limit and the shrinkage ratio.

1.2 This test method uses mercury which is a hazardous substance. Test Method D4943 does not use mercury and is an acceptable alternate to this procedure.

1.3 The liquid limit, plastic limit, and shrinkage limit are often collectively referred to as the Atterberg Limits in recognition of their formation by Swedish soil scientist, A. Atterberg. These water contents distinguish the boundaries of the several consistency states of cohesive soils.

1.4 This test method is performed only on that portion of a soil which passes the 425-[mu]m (No. 40) sieve. The relative contribution of this portion of the soil must be considered when using this test method to evaluate the properties of the soil as a whole.

1.5 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units are approximate and given for guidance only. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.

1.6 This standard does not purport to address all of the safety problems, 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. This test method involves the use of the hazardous material mercury, see Section 7.
