Description
The ITB-250 is specifically engineered to evaluate tensile strength through the application of uniform diametrical line compression on cylindrical test specimens. When subjected to vertical compression between two precision-machined cylindrical seating loading jaws, the specimen experiences induced indirect tensile stress along with a consequent orthogonal deformation. This testing assembly, also commonly referred to as the Brazilian test apparatus, is designed for seamless integration into standardized load frames. The system is comprised of three primary components: a specialized indirect tension fixture for specimen positioning, a calibrated load cell for force measurement, and a dedicated software module optimized for indirect tension test analytics. Collectively, these elements ensure high-precision and reliable data collection for the determination of tensile strength variables.
