    The measured yield strength and strain rate sensitivity of a sample steel characterized by a yield point instability were found to be much lower when servocontrolled machines were used when compared with open-loop machines. Several machine types and control systems were used to test the sample steel at different rates, and measurements of gauge length plastic strain rate were made. The data are used to evaluate the machine “hardness” strategy for calculating or predicting the plastic strain rate developed in a machine which has no direct strain rate control. The background to current procedures embodied in current british standards for tension testing is discussed, and tentative proposals are made to classify machine types and set appropriate testing rates so that the results of tension tests using different systems may be reconciled.
