    Abstract

    The evolution of nondestructive evaluation (NDE) to its current sophistication has been long and involved. The primary driving forces in the evolution of NDE are derived from economic considerations; the primary concern is to drive the total cost of a product to a minimum. The interdependence of the inspection process and the production process is considered using a probabilistic outlook and some historical perspectives. A generalized discussion is presented to demonstrate how cost savings might be incurred by the introduction of a reliable inspection system. The value of reliable NDE standards in reducing inspection uncertainty and the impact of this uncertainty on the total cost of a product is discussed.
