It has been 25 years Since BS1377 was last updated. In
this time technical innovations and our knowledge on
how best to perform some tests have moved on.

The CEN and ISO identified an urgent need for a set
of European testing methods when BSEN 1997 – 1
and BSEN 1997 – 2 (Eurocode 7) were being drafted.
Laboratory testing is an integral part of Eurocode 7,
therefore laboratories and engineers need to comply
with EC7 requirements. The drive is also to be part of
a Europe wide process of harmonising Standards to
remove trade barriers.

Where are we now

BS EN ISO 17892 – 1 Water Content and BS EN ISO
17892 – 2 Bulk Density were both published by BSI on
31st December 2014. On the same day
BS 1377 – 2:1990 Clause 3.2 Moisture Content
and BS 1377 – 2: 1990 Clause 7.1 to 7.4 Density
were withdrawn.

What is replacing BS1377

BSEN ISO 17892 will consist of an initial 12 geotechnical
laboratory test methods.
Part 1 – Water Content
Part 2 – Bulk Density
Part 3 – Particle Density
Part 4 – Particle Size Distribution
Part 5 – Incremental Oedometer
Part 6 – Fall – Cone Test
Part 7 – UCS Test
Part 8 – UU ‘’Quick’’ Triaxial Test
Part 9 – Consolidated Triaxial tests in Compression
Part 10 – Shear Box and Ring Shear Test
Part 11 – Permeability Test
Part 12 – Plastic and Liquid Limit Test

So what stage are we at

BSEN ISO 17892 – 3 Particle Density is expected to
be published around the end of 2015. It will supersede
BS1377 Part 2: 1990 Clauses 8.3 and 8.4

BSEN ISO 17892 – 4 Particle Size Distribution is
expected to be published around March 2016. It will
supersede BS1377 Part 2: 1990 Clauses 9.1 to 9.5

BSEN ISO 17892 – 5 Incremental Oedometer is
expected to be published around the middle of 2016.
It will supersede BS1377 Part 5: 1990 Clauses 3.1 to 3.7

BSEN ISO 17892 – 6 Fall Cone. There is no Fall Cone
in BS1377

BSEN ISO 17892 – 7 UCS Test

BSEN ISO 17892 – 8 UU Triaxial Test

BSEN ISO 17892 – 9 CD/CU Triaxial Test

BSEN ISO 17892 – 12 Plasticity Test

The above 4 are expected to be published by early 2017
They will supersede parts of BS1377 Part 2 large parts
of BS1377 Part 7 and all of BS1377 Part 8

BSEN ISO 17892 – 10 Shear Box and Ring Shear Test

BSEN ISO 17892 – 11 Permeability Test

The above 2 are expected to be published by the end of
2017. They will supersede large parts of BS1377 Part 5,
BS1377 Part 6 and BS1377 Part 7

Where does this leave you?

At the moment there are only a small selection of
laboratories who are accredited to the BSEN ISO
17892 tests? Until all the changes are implemented
engineers have a choice of scheduling to BS1377 or
to BSEN ISO 17892.
i2 Analytical is moving towards integration to
these new standards and will inform clients as
and when these have been implemented to our
accreditation status
These changes affect companies within the
geotechnical industry and i2 are here to assist you in
this journey.
