This European Standard was approved by CEN on 8 August 2015.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by

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 documents 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 221 Geosynthetics.
This second edition cancels and replaces the first edition (ISO 25619-2:2008), which has been
technically revised.
ISO 25619 consists of the following parts, under the general title Geosynthetics — Determination of
compression behaviour:
— Part 1: Compressive creep properties
— Part 2: Determination of short-term compression behaviour

INTERNATIONAL STANDARD ISO 25619-2:2015(E)
Geosynthetics — Determination of compression
behaviour —
Part 2:
Determination of short-term compression behaviour
1 Scope
This part of ISO 25619 specifies an index test method for determining the short-term compressive
behaviour of geosynthetics. It can be used to determine the deformation behaviour under short-term
compressive stress, e.g. after exposure to stress, liquids, or light.
This part of ISO 25619 can be used for quality control purposes. It is not intended to be used for
design purposes.
