ISO 15630-3: Steel for the reinforcement and prestressing of concrete – Part 9. Axial load fatigue test

Application

Axial Load Fatigue Testing Machine is specially designed to conduct axial load fatigue test on strand according to ISO 15630-3, the axial load fatigue test consists of submitting the strand to anxial tensile force, which varies cyclically aoccording to an sinusoidal wave-form of constant frequency in the elastic range. The test is carried out until failure of the strand or until reaching, without failure, the number of load cycles specified in the relevant product standard.

This machine is powered with a servo-hydraulic power pack which controlled through software where testing curves and testing results are automatically obtained, the actuator is mounted on the uppper crosshead who could be freely positioned on four posts to meet different vertical spaces on test pieces of different lengths.
