Description

Testometric offers high-capacity, precision testing systems designed for geotextiles, geogrids, and geocomposites used in civil, environmental, and geotechnical engineering. These systems feature powerful load frames, servo-hydraulic or motorized grips, and can be equipped with video extensometers for accurate, non-contact strain measurement—ideal for extensible, high-strength geosynthetic materials.

Engineered for high-accuracy testing of tensile strength, elongation, seam and joint strength, puncture, tear resistance, and long-term creep, Testometric systems support compliance with key ASTM and ISO standards. Custom fixtures and wide-width grips are available to simulate field conditions and ensure reliable performance evaluation for both R&D and quality assurance.

Key Features:

  • Long-travel frames for wide-width specimen testing
  • Hydraulic grips for consistent clamping under high loads
  • Video extensometers for non-contact strain measurement
  • Intuitive software with automatic reporting and graphing
  • Fully programmable test sequences and data logging

Testometric machines are used to determine key mechanical properties such as tensile strength, elongation, seam strength, puncture resistance, tear resistance, and creep behavior. Custom fixtures and software modules allow for testing in accordance with international geosynthetics standards across QC, R&D, and compliance workflows.

Typical Test Standards for Geosynthetics:

  • ISO 10319 – Tensile properties of geosynthetics
  • ASTM D5262 – Unconfined tension creep of geosynthetics
  • ASTM D7179 – Creep rupture of geosynthetics

Tear & Puncture Resistance:

  • ASTM D4533 – Trapezoid tearing strength of geotextiles
  • ASTM D6241 – Static puncture strength
  • ASTM D4833 – Index puncture resistance
  • ISO 12236 – Static puncture test for geotextiles and geocomposites

Seam/Joint Strength:

  • ASTM D4884 – Strength of sewn or bonded seams
  • ISO 10321 – Strength of joints in geosynthetics

Friction & Interaction:

  • ASTM D5321 – Determining the shear strength of geosynthetic interfaces
  • ASTM D7499 – Pullout resistance of geogrids

Testometric systems offer precise control, data logging, and reporting features essential for test labs and field validation of geotechnical designs.
