Bs 1377 Part 1

 



This Part of BS 1377 describes in-situ methods of test on soils for civil engi neering purposes, i.e. Tests made directly on the soil in place as distinct from laboratory tests, described in Parts 2 to 8 of this standard, for which samples first need to be taken. Bs 1377-1(2016): 2016: methods of test for soils for civil engineering purposes - part 1: general requirements and sample preparation: bs 5930(2015): 2015: code of practice for ground investigations: 4 dc: 0: na to bs en 1997-2 - uk national annex to eurocode 7 - geotechnical design - part 2: ground investigation and testing. It is part revision of clause 5 of BS 1377: 1975 which is superceded by amendment. BS 1377 was first published in 1948 and first appeared in metric form in 1975. The standard is in the process of being revised and will comprise nine separate parts. Part 7 of this standard describes methods of test for determining the shear strength parameters of soils in terms of total stresses, or (in the case of drained direct shear tests) in terms of effective stresses which are equal to total stresses.

BSI published the sixth edition of BS 1377-1:2016 Methods of test for soils for civil engineering purposes – General requirements and sample preparation on 29 July 2016.
First published in 1948, and last updated to its fifth edition in 1990, some would say that an update to the Standard was long overdue, but the previous edition served the geotechnical laboratory testing community superbly well for over a quarter of a century.

The new edition begins the process of overhaul of BS 1377 as a result of “Eurocode 7”, and in particular the publication of the first of the new International Laboratory Testing Standards in the BS EN ISO 17892 series. Three have already been published, while a fourth is expected before the end of 2016 and there are another eight in the pipeline for 2017/2018.

The main changes to BS 1377-1 are:
i. Extend the calibration interval for balances from 6-monthly to annual (this alone should save most laboratories at least the cost of the new Standard in one year);
ii. Amend the requirements for calibration certificates to bring them into line with BS EN ISO 17025;
iii. Make reference to the BS EN ISO 17892 series of Standards, instead of the superseded BS 1377 tests, where these have been published;
iv. Refer to ‘water content’ instead of ‘moisture content’ (BS EN ISO 17892-1); and
v. Remove references to withdrawn BS Standards, and replace with the current BS, EN or ISO Standards.
The sixth edition is not a complete re-write, but it is an important stepping stone as more and more daughter-Standards from Eurocode 7 appear.
BS 1377-3: 1990, which is currently being rewritten, is the next scheduled revision.
Copies of BS 1377-1:2016 are available to purchase (hard or e-copy) from the BSI shop here.

This Part of BS 1377 has been prepared under the direction of the Road Engineering Standards Policy Committee. It is part revision of clause 5 of BS 1377 : 1975 which is superceded by amendment. BS 1377 was first published in 1948 and first appeared in metric form in 1975. The standard is in the process of being revised and will comprise nine separate parts. Part 7 of this standard describes methods of test for determining the shear strength parameters of soils in terms of total stresses, or (in the case of drained direct shear tests) in terms of effective stresses which are equal to total stresses. None of these procedures therefore requires measurement of pore water pressure which is covered in part 8 of BS 1377. Shear strength is determined either by measuring the shearing force causing failure (direct shear tests) or by derivation from the measured compressive strength (unconfined or triaxial compression tests), these tests, and the apparatus used are described. Reference is made to Part 1 of the standard for general requirements that are relevant to all Parts. For the abstract for BS 1377 : 1990 Part 1 see IRRD 830334, for BS 1377 : 1990 Part 5 see IRRD 830335.
