The Twist Compression Tester is a laboratory tribology instrument designed to evaluate friction behavior and adhesive wear properties of materials under combined axial compressive load and relative torsional motion. You use this system to perform standardized tests under dry or lubricated conditions in accordance with ASTM G223. enabling reliable comparison of material friction coefficients, friction torque, and adhesive wear performance.
