ISO 13431:2024

This international standard specifies a method for determining the tensile creep behavior and tensile creep failure of geotextiles and related products without specimen confinement. The use of this standard is limited to products and applications for which the risk of collapse of a structure following premature failure or a variation in the strain/time curve of the reinforcement under constant load is of capital importance. Since the test is carried out over a long period of time and the procedure is complex, it is therefore recommended not to consider the test as a routine test for quality control. Test results may not be representative of product performance when subjected to ground pressures.
