Full title and description

ISO 10319:2024 — Geosynthetics — Wide-width tensile test. This International Standard specifies an index tensile test method using a wide-width strip for determining the tensile properties of geosynthetics (polymeric, glass and metallic), including procedures for measuring tensile force, elongation characteristics and calculating secant stiffness, maximum load per unit width and strain at maximum force.

Abstract

This document describes a wide‑width strip tensile test applicable to most geosynthetics (woven and nonwoven geotextiles, geocomposites, knitted geotextiles, geonets, geomats, geogrids and metallic products). It includes procedures for testing conditioned and wet specimens and indicates singular points on the tensile force–extension curve. The method excludes polymeric or bituminous geosynthetic barriers but applies to clay geosynthetic barriers.

Scope

ISO 10319:2024 provides an index test method for determining tensile properties of a wide range of geosynthetic products using specimens held across their full width in tensile grips. The scope covers the measurement of tensile force and extension, calculation of secant stiffness, maximum load per unit width and strain at maximum force, and guidance on specimen preparation, gripping methods and test speeds; it does not apply to polymeric or bituminous geosynthetic barriers but does apply to clay geosynthetic barriers.

Key topics and requirements

• Wide‑width strip specimen geometry and preparation (specimen held across full width).
• Measurement of tensile force and elongation to failure; identification of singular points on the force–extension curve.
• Procedures to calculate secant stiffness, maximum load per unit width and strain at maximum force.
• Requirements for grips/jaws selection (compressive hydraulic jaws, capstan grips) and recommended winding schemes for capstan grips.
• Defined strain‑rate/test speed guidance (typical target: 20 %/min strain rate in the true gauge length, with adjustments for low‑strain products).
• Conditioning and wet specimen test procedures where applicable.
• Scope limits: not applicable to polymeric/bituminous barriers; applicable to clay geosynthetic barriers.

Typical use and users

Used by geotechnical and civil engineers, materials and quality control laboratories, geosynthetic manufacturers, researchers and specification writers to assess and compare tensile properties of geosynthetic products for design, quality assurance and product development. Test laboratories adopt ISO 10319 when uniform, repeatable wide‑width tensile data are required for product specifications and comparative evaluation.

Related standards

ISO 10319:2024 replaces ISO 10319:2015 (withdrawn). It is typically used alongside other geosynthetic and geotextile test methods (for example ASTM D4595 for wide‑width tensile testing under ASTM procedures) and with regional/adopted versions such as EN ISO 10319:2024.
