Compliance Standards
ISO6892, BS4449, ASTM C39, ISO75001, ASTM A370, ASTM E4, ASTM E8, BSEN standards
Host Structure Features
- Optimized layout with tank below main host and testing zones strategically positioned
- Robust four-column, two-lead screw structure for exceptional stability
- Integrated one-piece design provides ultra-high structural stiffness
- Adjustable clearance lead screw-nut mechanism eliminates transmission backlash
- Precision gap sealing technology enhances accuracy and extends hydraulic system life
Measurement & Control System
- Full-digital control system with closed-loop control over test force, deformation, and displacement
- Multiple control functions: constant stress, constant strain, constant-speed test force, constant displacement
- Real-time display of peak test force, specimen deformation, piston displacement, and test curves
- Mouse-operated interface with intelligent expert system control mode
Safety & Protection Systems
- Overload protection activates when test force exceeds 2-5% of maximum range
- Travel limit protection automatically shuts down pump motor at preset upper position
