ABSTRACT
If the peak torque pulses are read with very high frequency response instruments, the peak torque readings can be used to verify the setup of the pulse tool. For such tests to be meaningful, the joint spring rate and friction coefficients must be controlled or standardized. At the present time no standard, ISO or otherwise, exists as a guide to define the test joints for qualification of pulse or impact type tools. Thus the individual user must develop his own standards to meet his specific tool testing requirements.
