Non destructive techniques (NDT) offer many possibilities for evaluating concrete properties. They can provide estimates of input data useful for assessing the residual service life or reliability of infrastructures, among them power plants. The issue is to know the quality of such estimates. The weaknesses of NDT have been pointed for a long time, since they are not considered as a reliable mean for providing quantitative data. Several recent research programs have resulted in significant improvements. Several issues are addressed here: (a) the adequacy of a NDT for a given purpose, (b) the quality/uncertainty of the material assessment provided by using one NDT, (c) the possibility of combining several techniques, so as to reduce the effect of uncontrolled parameters. For each of these issues, some general criteria are defined and it is explained how to derive quantitative information enabling their practical use in a decision process.
