This International Standard describes an index test method for the determination of the tensile properties of
geosynthetics, using a wide-width strip. The method is applicable to most geosynthetics, including woven
geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles and felts. The method is also applicable
to geogrids and similar open-structure geotextiles, but specimen dimensions might need to be altered. This
test is not applicable to polymeric or bituminous geosynthetic barriers, while it is applicable to clay
geosynthetic barriers.
The tensile test method covers the measurement of load elongation characteristics and includes procedures
for the calculation of secant stiffness, maximum load per unit width and strain at maximum load. Singular
points on the load-extension curve are also indicated.
Procedures for measuring the tensile properties of both conditioned and wet specimens are included in this
International Standard.
