Standard : ASTM D7012
This advanced test system is specially built for automatic test & precise determination of intact rock core specimens elastic properties under uniaxial condition, fully compliant with ASTM D7012. By applying controlled axial loads and capturing axial and lateral strains, the system automatically measures Young’s Modulus & Poisson’s Ratio using high precision axial & lateral strain gauges.
Equipped with rigid loading frame, closed-loop control & high-resolution data acquisition, the machine measures accurate stress strain relationships of rock core. The integrated test software enables intuitive operation, real-time monitoring, and automatic calculation of elastic parameters. Combined with robust controller, smart control features and high-resolution data acquisition, the system ensures repeatable, standard-compliant and research-grade results across a wide range of rock types.
Features:-
- Rigid high-stability compression frame ensures stability and minimal frame deformation during test.
- Precision-aligned platens with spherical seating for uniform loading.
- High-performance hydraulic system for smooth and accurate loading rates.
- Flexible Smart Controller enables multi-deformation capture based on different load settings.
- Closed-loop control ensures precise loading rates per ASTM D7012 requirements.
- Real-time stress–strain graph with automatic modulus and Poisson's ratio calculation.
- Supports multiple channels for axial & lateral strain gauges or displacement transducer input.
- Easy setting user-defined test parameters with preset templates according to ASTM D7012.
- Raw data export to Excel for reporting and further analysis of test results.
