In the realm of tensile and compression testing machines, the test speed, denoted in “○○ mm/min,” signifies the rate of displacement per unit time during the application of a load. Nevertheless, specific tests mandate compliance with standards dictating the test to be executed at “N/min,” reflecting the rate of load change per unit time. This feature guarantees the ongoing calibration and reconfiguration of load values to sustain the predetermined rate of load fluctuation throughout the test duration.
