Leister EXAMO 600F USB Membrane Testing Device

The Leister EXAMO 600F USB is a 200 W calibrated membrane testing device capable of applying up to 4000 N tensile force across a 600 mm test length, designed for peel adhesion, tensile strength, and shear resistance testing of geomembrane weld seams in compliance with DVS and ASTM standards – with digital parameter display and USB data export for audit-ready quality assurance documentation.

Standard-Compliant Weld Seam Testing for Geomembrane and Elastic Membrane Applications

Civil and environmental infrastructure projects involving geomembrane containment systems – landfills, reservoirs, canal liners, gas barriers, and environmental isolation structures – carry quality assurance obligations that extend beyond visual weld inspection. Regulatory frameworks, project specifications, and international standards including DVS and ASTM require destructive testing of weld seams at defined intervals, with test results recorded, traceable, and demonstrably obtained using calibrated instruments operating to recognised test methods.

For highly elastic geomembrane materials, the additional constraint is test length. Standard tensile testers with limited travel cannot accommodate the full elongation of elastic membranes before failure, producing truncated results that do not reflect true material behaviour under the peel or shear forces the weld seam will encounter in service. The EXAMO 600F USB addresses this with a 600 mm maximum test length – sufficient to capture the complete failure profile of highly elastic membranes – combined with a 4000 N force capacity, variable crosshead speed from 20 to 550 mm/min, and the digital parameter recording that transforms individual test events into a structured, exportable quality assurance dataset.

EXAMO 600F USB Testing Capabilities and Instrument Engineering

• 4000 N Tensile Force Capacity: Applies up to 4000 N of controlled tensile force to weld seam specimens during peel and shear testing, providing the force range required to test the full range of geomembrane materials and thicknesses encountered in civil and environmental engineering applications.
• 600 mm Maximum Test Length for Elastic Membranes: The extended test travel accommodates the elongation characteristics of highly elastic geomembrane materials, enabling valid peel and tensile tests to be completed through to specimen failure rather than terminating prematurely due to insufficient travel – a limitation that invalidates results and compromises standard compliance.
• DVS and ASTM Standard Compliance: Pre-configured at production to conduct membrane tests in accordance with DVS and ASTM testing standards, eliminating the parameter setup and calibration procedures that introduce variability into test programmes and ensuring results are directly comparable with standard reference data and project specification requirements.
• Digital Parameter Display: Provides real-time digital readout of stretching, maximum force, tearing force, test speed, and position throughout each test cycle – giving the operator immediate visibility of all parameters relevant to result validity and weld seam performance assessment without manual recording or post-test reconstruction.
• USB Data Export: Test parameters and results are saved directly to a USB stick, generating a structured digital record of each test event that supports audit trails, quality assurance reporting, and project documentation submission to clients, certifiers, and regulatory bodies.
• Factory Calibrated on Delivery: The EXAMO 600F USB is calibrated during production before shipment, enabling immediate deployment to active testing programmes without on-site calibration procedures – reducing commissioning time and ensuring the instrument operates to verified accuracy from first use.
• Metal Box Anchorage for Testing Stability: The instrument is firmly anchored within its metal transport and storage box, which functions as a stable testing platform during operation – eliminating the need for a separate test bench or mounting fixture and enabling testing to be conducted wherever the box can be positioned.
• Immediate Operational Readiness: The operating manual is integrated into the lid of the metal box, accessible at the point of use without requiring a separate document. On opening the lid, the instrument is anchored, the manual is visible, and membrane testing can begin without additional preparation.
• Variable Crosshead Speed from 20 to 550 mm/min: Adjustable test speed across a wide range enables the EXAMO 600F USB to be configured for the specific crosshead speed requirements of different DVS and ASTM test methods, supporting compliance across the full range of applicable geomembrane testing standards.

Membrane Weld Quality Testing Applications in Civil and Environmental Engineering

• Geomembrane Weld Seam Peel Adhesion Testing: Conducts destructive peel tests on hot wedge and extrusion weld seams in PE, HDPE, and highly elastic geomembrane materials to DVS and ASTM standard requirements, producing the force and elongation data that project quality assurance programmes specify at defined installation intervals.
• Tensile Strength Verification of Membrane Welds: Applies controlled tensile load to weld seam specimens to verify that joint strength meets the minimum values specified in project documentation and material standards – providing the numeric data that visual inspection alone cannot deliver.
• Shear Resistance Testing for Containment Liner Systems: Tests the shear resistance of geomembrane weld seams in landfill containment, reservoir lining, and environmental barrier installations where weld seams are subject to differential loading and must demonstrate resistance to in-plane shear forces.
• Quality Assurance Documentation for Project Handover: The USB data export capability supports the generation of structured test records for inclusion in as-built quality assurance documentation packages, providing clients, engineers, and regulators with traceable, instrument-generated test data for each weld seam verification event on civil infrastructure projects across Oman and the GCC.
• Laboratory and Site Testing Programme Integration: The anchored metal box format and immediate operational readiness make the EXAMO 600F USB suitable for deployment in both fixed laboratory testing environments and on-site quality control facilities, supporting consistent test methodology across different project phases and locations.
