ISO/CEN PARALLEL ENQUIRY
This draft International Standard is a draft standard developed within the European Committee for
Standardization (CEN) and processed under the CEN-lead mode of collaboration as defined in the
Vienna Agreement. The document has been transmitted by CEN to ISO for circulation for ISO member
body voting in parallel with CEN enquiry. Comments received from ISO member bodies, including those
from non-CEN members, will be considered by the appropriate CEN technical body. Should this DIS be
accepted, a final draft, established on the basis of comments received, will be submitted to a parallel two-
month FDIS vote in ISO and formal vote in CEN.
In accordance with the provisions of Council Resolution 15/1993 this document is circulated in
the English language only.
Conformément aux dispositions de la Résolution du Conseil 15/1993, ce document est distribué
en version anglaise seulement.
To expedite distribution, this document is circulated as received from the committee secretariat.
ISO Central Secretariat work of editing and text composition will be undertaken at publication
stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du
secrétariat du comité. Le travail de rédaction et de composition de texte sera effectué au
Secrétariat central de l'ISO au stade de publication.
THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE
REFERRED TO AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.

ISO/DIS 22282-6
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22282-6 was prepared by Technical Committee ISO/TC 182, Geotechnics, Subcommittee SC 1,
Geotechnical investigation and testing and by Technical Committee CEN/TC 341, Geotechnical investigation
and testing in collaboration.
ISO 22282 consists of the following parts, under the general title Geotechnical investigation and testing —
Geohydraulic testing:
⎯ Part 1: General rules
⎯ Part 2: Water permeability tests in a borehole using open systems
⎯ Part 3: Water pressure test in rock
⎯ Part 4: Pumping tests
⎯ Part 5: Infiltrometer tests
⎯ Part 6: Water permeability tests in a borehole using closed systems

DRAFT INTERNATIONAL STANDARD ISO/DIS 22282-6

Geotechnical investigation and testing — Geohydraulic
testing —
Part 6:
Water permeability tests in a borehole with packer and pulse-
litre stimulation
1 Scope
This standard specifies requirements for the determination of the local permeability in soils and rocks below or
above the ground water table in a closed system by the water permeability tests as part of the geotechnical
investigation services according to EN 1997-1 and prEN 1997-2.
-8
The tests are used to determine the permeability coefficient k in low permeable soil and rock lower than 10
m/s. It can also be used to determine the transmissivity T and the storage coefficient S.
NOTE The water pressure test in rock is covered by ISO 22282-3.
