摘要

A metric for the application factor, g(AP), is discussed. The factor g(AP)functionally captures the degradation in NDE reliability due to operationalconstraints related to materials being inspected and the NDE equipment being used.It was first suggested as part of the reliability formula, R = f(IC) - g(AP) - h(HF), coined during the 1997 European-American Reliability Workshop held inBerlin. The intrinsic capability of the method, f(IC), establishes a reliabilityupper bound while the factor h(HF) captures reductions in NDE reliabilityattributable to human factors.The issue of NDE reliability is considered both as it applies to flaw detectionand dimensional measurements. Examples discussed include (1) radiographic crackdetection in welded ferritic tubes, (2) ultrasonic detection of pores in electronbeamwelds, and (3) radiographic-projection wall thickness measurement of isolatedtubes found in petro-chemical plants.Considerations will be given to the different types and categories of applicationparameters suitable to the experimental examples. Methods for combining g(AP) withf(IC) and h(HF) will also be discussed, thus addressing the issue of how overallNDE reliability might become quantified and modeled.
