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).

Geosynthetics — Wide-width tensile test
1 Scope
This document specifies an index test method for the determination of the tensile properties of geosynthetics
(polymeric, glass and metallic), using a wide-width strip. This document is applicable to most geosynthetics,
including woven geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles, geonets, geomats
and metallic products. It is also applicable to geogrids and similar open-structure geotextiles, but specimen
dimensions will possibly need to be altered. It is not applicable to polymeric or bituminous geosynthetic
barriers, but it is applicable to clay geosynthetic barriers.
This document specifies a tensile test method that covers the measurement of tensile force, elongation
characteristics and includes procedures for the calculation of secant stiffness, maximum load per unit width
and strain at maximum force. Singular points on the tensile force-extension curve are also indicated.
Procedures for measuring the tensile properties of both conditioned and wet specimens are included in this
document.

4 Principle
A specimen is held across its entire width in a set of clamps or jaws (see Figure 3) of a tensile testing
machine operated at a constant cross-head speed. A longitudinal force is applied to the specimen until the
specimen ruptures. The type of jaws used are selected according to the type and tensile strength of the
tested product; compressive hydraulic jaws [Figure 3 a), c), d)] and capstan grips [Figure 3 b), e), f)] may be
used. For capstan grips, it can be useful to wind the specimen in an “S-shape” scheme around the capstan
clamps or in a “B-shape” scheme, as shown in Figure 3 f).
The tensile properties of the specimen are calculated from machine scales, dials, autographic recording
charts or an interfaced computer. A constant test speed is selected so as to give a strain rate of (20 ± 5) % per
minute in the true gauge length of the specimen, except for products that exhibit a low strain, i.e. less than
or equal to 5 %. For these products, e.g. glass, the speed is reduced so that the specimen breaks in (30 ± 5) s.
The basic distinction between the current method and other methods for measuring tensile properties of
products is the width of the specimen. In the current method, the width is greater than the length of the
specimen, as some geosynthetics have a tendency to contract (neck down) under tensile force in the gauge
length area [see Figure 3 c)].
Greater width reduces the contraction effect of such products and provides a relationship closer to the
expected product behaviour in the field, as well as a standard for comparison of geosynthetics.
For information on strain, extension measurements are made by means of an extensometer, which follows
the movement of two reference points on the specimen. These reference points are situated on the specimen
symmetry axis, which is parallel to the applied tensile force, and are separated by a distance of 60 mm
(30 mm on each side of the specimen symmetry centre). This distance can be adapted for some types of
geosynthetics, like geogrid, in order to include at least one row of nodes or internal junctions.
5 Reagents
The usual laboratory apparatus and, in particular, the following shall be used.
— Use only reagents of recognized analytical grade and only distilled water or water of equivalent purity.
— Distilled water, for wet specimens only, conforming to Grade 3 of ISO 3696.
— Non-ionic wetting agent, for wet specimens only.
— The wetting agent used shall be a general purpose polyoxyethylene glycol alkyl ether at 0,05 % volume.
6 Apparatus
The usual laboratory apparatus and, in particular, the following shall be used.
6.1 Tensile testing machine (constant cross-head speed), conforming to ISO 7500-1, Class 1 or better, in
which the rate of increase of specimen length is uniform with time, fitted with a set of clamps or jaws which
are sufficiently wide to hold the entire width of the specimen and equipped with appropriate means to limit
slippage or damage.
NOTE 1 It is useful if one clamp is supported by a free swivel or universal joint to compensate for uneven distribution
of force across the specimen.
