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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
 an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
 an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
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/TS 22476-11 was prepared by Technical Committee ISO/TC 182, Geotechnics, Subcommittee SC 1,
Geotechnical investigation and testing.
ISO/TS 22476 consists of the following parts, under the general title Geotechnical investigation and testing —

Introduction
The flat dilatometer test covers the determination of the in situ strength and deformation properties of fine
grained soils using a blade shaped probe having a thin circular steel membrane mounted flush on one face.
Results of flat dilatometer tests are mostly to obtain information on soil stratigraphy, in situ state of stress,
deformation properties and shear strength.
The basis of the test consists of inserting vertically into the soil a blade–shaped steel probe with a thin
expandable circular steel membrane mounted flush on one face and determining, at selected depths or in a
semi-continuous manner, the contact pressure exerted by the soil against the membrane when the membrane
is flush with the blade and subsequently the pressure exerted when the central displacement of the membane
reaches 1,10 mm.
The flat dilatometer test is most appropriate in clays, silts and sands where particles are small compared to
the size of the membrane.
