Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
The demand for quantified nondestructive evaluation (NDE) has increased significantly with increasing use of damage tolerance in engineering design and acceptance. The metric that has been developed to quantify NDE capabilities and to provide a method of data exchange is the probability of detection (POD). Generation of a characteristic POD curve requires: (1) passing a statistically significant number of representative flaws through and NDE procedure; (2) the flaw distribution must be near the expected NDE detection threshold; (3) flaws located in representative materials, geometries and surface conditions; (4) systematic control of NDE procedures; and (5) documentation of the results of application [1–3].
