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.

This first edition of ISO 12960 cancels and replaces ISO/TR 12960:1998, which has been technically
revised. This document consolidates ISO/TR 12960:1998 and EN 14030:2001 and replaces both.

ISO 12960:2020(E)
Introduction
In nearly all applications, geotextiles and geotextile-related products (hereinafter, geotextile products)
can be in contact with aqueous solutions of acids, bases or dissolved oxygen. The resistance of geotextile
products to these chemicals depends, on the one hand, on polymer formulation, processing, textile
structure and the presence of existing damage and, on the other hand, on the composition of the liquid
and in situ conditions such as temperature, pressure and the presence of further mechanical stress.
It is the purpose of this document to provide methods of screening (index testing) the resistance of
geotextile products to acids and bases.
Since an index test requires exposure times that are short compared to the expected lifetimes of
geotextile and geotextile-related products, the process needs to be accelerated. The data obtainable
are suitable for screening but not for deriving performance data such as lifetime, unless supported by
further evidence.
INTERNATIONAL STANDARD ISO 12960:2020(E)
Geotextiles and geotextile-related products — Screening
test methods for determining the resistance to acid and
alkaline liquids
1 Scope
This document specifies methods for screening the resistance of geotextile and geotextile-related
products to liquids while not subjecting them to external mechanical stress.
It is applicable to all geotextiles and geotextile-related products.
