This Part of BS 1377 describes methods of test for the determination of the consolidation characteristics of soils when subjected to changes in the applied effective stress, the permeability characteristics of sands, the susceptibility of clays to internal erosion by water, and the susceptibility of soils to heave in freezing conditions.
Reference is made to some of the classification tests described in BS 1377 : Part 2, and to some of the methods of soil compaction described in BS 1377 : Part 4 .
Reference is made to Part 1 for general requirements that are relevant to all Parts of this British Standard and for methods of preliminary preparation of soil and specimens for testing.
