Methods of test for Soils for civil engineering purposes BS 1377-3:1990

This Part of BS 1377 has been prepared under the direction of the Road Engineering Standards Policy Committee. It is a revision of clause 3 of BS 1377:1975 which is superseded by amendment. BS 1377 was first published in 1948 and first appeared in metric form in 1975. BS 1377:1975 which has now been withdrawn is replaced by the following Parts of BS 1377:1990:
— Part 1: General requirements and sample preparation;
— Part 2: Classification tests;
— Part 3: Chemical and electro-chemical tests;
— Part 4: Compaction-related tests;
— Part 5: Compressibility, permeability and durability tests;
— Part 6: Consolidation and permeability tests in hydraulic cells and with pore pressure measurement;
— Part 7: Shear strength tests (total stress);
— Part 8: Shear strength tests (effective stress);
— Part 9: In-situ tests.
Reference should be made to Part 1 for further information about each of the Parts. In this Part of BS 1377 the test methods described in the 1975 edition have been retained with some modification, and the following methods of test have been introduced:
a) determination of loss on ignition;
b) determination of carbonate content;
c) determination of chloride content;
d) determination of total dissolved solids content;
e) determination of electrical resistivity;
f) determination of the redox potential;
