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.

INTERNATIONAL STANDARD ISO 10772:2012(E)
Geotextiles — Test method for the determination of the filtration
behaviour of geotextiles under turbulent water flow conditions
1 Scope
This International Standard describes a test method for determining the soil passing through a geotextile filter
when exposed to turbulent external water flow conditions.
The test provides a value for one specific type of soil as a performance test for the design of erosion protection
layers with geotextile filters in hydraulic engineering applications.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.
ISO 9862, Geosynthetics — Sampling and preparation of test specimens
ISO 12956, Geotextiles and geotextile-related products — Determination of the characteristic opening size
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply:
3.1
soil passing value
S
pv
cumulative average soil passing value for the three specimens after the final stage
3.2
cohesion
c
u
undrained cohesion of the test soil
3.3
plasticity index
I
P
plasticity of test soil
4 Principles
The test simulates the exposure of geotextiles to turbulent conditions such as those that occur during wave
action, the passage of a ship, etc. The filtration stability of the geotextile is determined by measuring the
amount and rate of soil passing through the geotextile during the test.
5 Test method
The mechanical filtration stability of the test soil and of similar soils is determined by measuring the soil passing
through the
