Perhaps for soil shear strength testing in civil engineering???

Consolidated drained (CD) shear box tests are used to determine the effective shear strength parameters of soils
as recommended both by British and American standards. The effective shear strength parameters of soils can be
determined using consolidated isotropic drained (CID) triaxial tests, consolidated isotropic un-drained (CIU) as
specified in BS 1377: Part 8 (1990) and Head (1986). CD shear box tests as specified in ASTM D 3080-98 (1998)
and Head (1994) can also determine the effective shear strength parameters of soils. For cut slopes, the effective
stress (drained or long-term conditions) is normally more critical than the total stress (un-drained condition). It is
usual to carry out the slope stability analysis in terms of effective stress for cut slopes as reported by Chin and Meng
(2004) and Gue and Fong (2006). In CD shear box tests, the soil specimen is soaked and normal force is applied
until all consolidation settlements are completed.
