This document specifies the test method for the determination of the magnitude of one-dimensional collapse that occurs when unsaturated soils are inundated with water. This method is used to determine two parameters related with the collapsibility of a soil: the collapse index and the collapse potential. This test method specifies the technique for specimen preparation, the apparatus and the procedure for quantifying the amount of height change associated with collapse and procedures for reporting test results. The procedure given in this test method is applicable to both undisturbed samples or remolded specimens. It is a one single sample test procedure.
