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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO [had/had not] received notice of
(a) patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 221 Geosynthetics, in collaboration with
the European Committee for Standardization (CEN) Technical Committee CEN/TC 189, Geosynthetics, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 13428:2005), which has been technically
revised.
The main changes are as follows:
— the normative references have been updated;
— Figure 1 has been corrected;
— the thickness of lead plate has been modified to 2,0 mm.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Geosynthetics — Determination of the protection efficiency of
a geosynthetic against impact damage
1 Scope
This document describes an index test for the determination of the protection efficiency of a geosynthetic on
a hard surface, exposed to the impact load of a hemispherical object.
The index test measures the change in thickness of a thin lead plate lying between the geosynthetic and a
rigid support.
It is also used as a performance test, by using the real rigid surface to protect and the real sequence of
geosynthetics.
The test is applicable to all geosynthetics with apertures smaller than 15 mm (maximum size).
