Описание (английский):

This document specifies a method for determining the tensile creep and creep rupture behaviour of geotextiles and geotextile-related products in an unconfined situation. Application of this document is limited to products and applications where the risk of collapse of a structure due to premature failure or to strain and time variation of the reinforcement under constant load is of essential importance.

Overview

ISO 13431:2024 - Geotextiles and geotextile-related products - Determination of tensile creep and creep rupture behaviour - specifies a laboratory method to assess tensile creep and creep rupture of geotextiles and related products in an unconfined situation. The standard is intended for cases where long‑term strain and time‑dependent variation under constant load could cause premature failure or collapse of a structure. ISO 13431:2024 updates the original 1999 edition and is published in cooperation with CEN.

Keywords: ISO 13431:2024, geotextiles, tensile creep, creep rupture, tensile creep behavior, geotextile testing

Key Topics and Requirements

Scope: Tests apply to products and applications where the risk from creep is essential (unconfined conditions).

Specimens:

Sampling per ISO 9862.
Minimum of 12 specimens for tensile creep and 12 specimens for creep rupture (more by agreement).
Nominal gauge length set clear of grips; minimum gauge length ≥ 200 mm (geogrids: ≥ two full elements).
Technically Representative Width (TRW): small width exhibiting strength/strain within ±5% and ±20% of wide‑width values.
Width rules: 200 mm for materials with lateral contraction >10%; otherwise TRW or geogrid element rules apply.

Test parameters and definitions:

Pre‑tension force = 1% of tensile strength but not more than 10% of tensile creep load.
Tensile creep load expressed as % of tensile strength (includes pre‑tension and device load).
Loading time, creep time, time to tensile creep rupture are defined and recorded in seconds/hours.

Apparatus and measurements:

Requirements for grips, loading system, strain and time measurement systems are specified.
Charts of temperature and humidity are required in test reports for the test duration.

Reporting: Test report content required (including conditions, specimen dimensions, load levels, creep curves).

Applications and Who Uses It

ISO 13431:2024 is used by:

Geotechnical engineers and designers assessing long‑term reinforcement performance (retaining walls, reinforced slopes, embankments).

Manufacturers and quality control labs for product verification and R&D.

Specifiers, contractors, and testing laboratories needing documented creep resistance evidence for safety‑critical structures. Practical uses include selection of geotextiles for long‑term load bearing, comparison of products for reinforcement projects, and failure‑mode analysis where time‑dependent deformation matters.
