Geomembrane tear strength tester
Standard
- ASTM D7176(Standard Test Method for Determining the Resistance of Geomembranes to Slow Steady-State Strain)
- ISO 17548(Geosynthetics - Determination of Tear Resistance)
- GB/T 17642(China National Standard for Geomembrane Mechanical Properties)
Product Advantages
- Unmatched Precision
- High-resolution pressure sensor (±0.1 kPa accuracy) captures even subtle membrane deformations, critical for HDPE, LDPE, and PVC geomembranes.
- Automated Testing Protocols
- Programmable test cycles simulate slow strain (0.1–10 mm/min) and rapid fracture events, replicating real-world installation and operational stresses.
- Safety First Design
- Explosion-proof test chamber, emergency pressure relief valve, and laser-guided specimen alignment minimize operator risk.
- Industrial-Grade Durability
- Stainless steel test cavity, corrosion-resistant hydraulic system, and anti-vibration feet ensure long-term reliability in demanding labs.
- User-Centric Operation
- 10.1-inch capacitive touchscreen with multilingual support (English, Spanish, Arabic, Japanese) and AI-powered data analysis.
Product Features
- Multi-Mode Testing:
- Constant Pressure Test: Applies static load to assess long-term creep resistance.
- Gradient Pressure Test: Increases pressure at 0.1–10 kPa/s to simulate sudden hydraulic impacts.
- Cyclic Loading: Replicates tidal/wave pressure fluctuations for coastal lining applications.
- Real-Time Monitoring:
- High-speed camera (1,000 FPS) captures fracture initiation and propagation, with thermal imaging for localized stress analysis.
- Data Management:
- Cloud-compatible software stores 10,000+ test results, generates ISO/ASTM-compliant reports, and supports barcode scanning for sample tracking.
- Universal Specimen Compatibility:
- Adjustable clamps accommodate geomembranes up to 2mm thick, including textured and smooth surfaces.
