Machine Structure
The system typically consists of a load frame, crosshead, load cell, grips or fixtures, extensometer, and control software. The frame applies force while sensors measure the specimen response.
Technical Specifications
Typical Specification Range:
- Load Capacity: 1 kN – 600 kN
- Force Accuracy: ±0.5% of reading
- Crosshead Speed: 0.001 – 1000 mm/min
- Displacement Accuracy: ±0.01 mm
- Standards: ISO 7500-1, ASTM E8/E8M, ASTM D638
Applications
Commonly used in metals, plastics, composites, textiles, and rubber testing. Ensures material compliance and supports R&D performance validation.
Maintenance
Calibrate load cells annually, verify extensometer accuracy monthly, and lubricate screw drives periodically to maintain precision.
Technical Support
Manufacturers typically provide calibration certificates, training materials, and spare parts documentation per ISO/ASTM standards.
