This Part of BS 1377 describes in-situ methods of test on soils for civil engineering purposes, i.e. tests made directly on the soil in place as distinct from laboratory tests.
The methods for test have been arranged in groups either according to the purpose of the test or the mode of execution. These groups are as follows.
• Five methods for the determination of the in-situ density
• Three methods for the determination of penetration resistances
• Four methods for the determination of the vertical deformation and strength
characteristics
• Two methods for the determination of the in-situ corrosivity characteristics.
BS 1377-9 is a revision of the in-situ test methods described in BS 1377:1975 which are superseded by amendment.
