Standards Development

Scope

Scope remains unchanged. This Part of BS 1377 describes in-situ methods of testing 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BS 1377-9 is a revision of the in-situ test methods described in BS 1377:1990, which are superseded by amendment.

Purpose

The geotechnical testing standards contained in BS 1377 series need to be amended, as they contain tests which now have new ISO/CEN standards, as well as tests now outside the scope of CEN/TC 341 and ISO/TC 182 Geotechnical investigation standards, but still in demand and carried out by UK laboratories and site investigation companies, which are or will become UKAS accredited. These tests are also performed outside of Europe, particularly in and where there are no equivalent standards, such as the Middle East.
