The structural integrity of many modern components, systems and structures depends, in part, on a high confidence in finding a flaw of a given size at the time of production and/or at periodic maintenance inspections performed during life-cycle service. The flaw detection capability of an applied NDT procedure is described by its probability of detection (POD). Demonstration of flaw detection capabilities is required for the validation of NDE procedures used of inspection and for qualification of operators who perform inspections to support structural integrity. Requirements for demonstration include consideration of multiple variables involved in the development and application of an NDE procedure. This paper discusses considerations and requirements for demonstrating/validating the capability of an NDE procedure and for qualification of operators who perform inspections of critical hardware and systems. Variances in approach by NDE method are discussed in terms of data requirements. Data are presented from the point of view of aerospace and civil applications. © 2000 American Institute of Physics.
