Standard Triaxial Systems

This rock testing system is designed and manufactured to perform uniaxial and triaxial tests according to ASTM standards and suggested ISRM methods. The modular system can be configured with a variety of hydraulic load frames and power packs. Different triaxial cells can be used with adapters for different sample sizes from 25 mm to 100 mm. High pressure systems with customized attachments, advanced software packages and further accessories can be developed to suit your specific testing needs. This modular constructed system can be configured with different jigs and attachments in order to perform uniaxial compressive strength, triaxial strength, post failure, bending, indirect tensile, direct tensile, fracture toughness and creep tests.
