Rationale

This guide would also give guidance on current practices for very high cycle fatigue testing of 10 million cycles to 1 billion cycles or more using machines capable of high cyclic frequencies. The current fatigue standards E466 and E606 do not address some of the key issues regarding machines that can achieve frequencies in excess of 100 hz to as high as 20 khz, such as dynamic load verification, methods of control, data sampling best practices, open loop control in the case of ultrasonic test machines ect. Users of this standard would be researchers interested in creating fatigue curves that approaching the materials end use life cycle.
