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 22282-2 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 341, Geotechnical investigation and testing, in collaboration with Technical Committee ISO/TC 182,
Geotechnics, Subcommittee SC 1, Geotechnical investigation and testing, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
ISO 22282 consists of the following parts, under the general title Geotechnical investigation and testing —

Water permeability tests in a borehole using open systems
1 Scope
This part of ISO 22282 specifies requirements for the determination of the local permeability in soils and rocks
below and above groundwater level in an open hole by water permeability tests as part of the geotechnical
investigation services according to EN 1997-1 and EN 1997-2.

4 Test principle
The test is based on the assumption that the test section is isolated and located above or below the
groundwater surface.
The results can vary depending on the test type chosen (water withdrawal or injection) according to the purpose
of the test.
Three test methods are available:
−6
a) Constant flow rate test method (suitable for k-value greater than 10 m/s)
This test consists of producing a change in hydraulic head in a section of a borehole by injecting or withdrawing
a constant flow rate. The change in hydraulic head is measured against time.
−6 −9
b) Variable head test method (suitable for k-value between 10 m/s and 10 m/s)
This test consists
