    Abstract

    Reliability of J-R-curve testing is extremely important for evaluation of nuclear components. In this work the results of a Nordic J-R-curve round robin test programme are presented. The results show a large amount of scatter. It was not possible to conclusively state whether the scatter is due to the material inhomogeneity or to the different laboratory practices. The round robin exercise, however, does give valuable information regarding the reliability to be expected in J-R-curves obtained by standard procedures. It is evident that the present J-R-curve testing procedures are still in need of refinement.
