The results of the PISC I round robin test of the ASME type procedure showed a very large dispersion. The amplitude of response of all defects varied widely. Scatter on detection and sizing in PISC I was such, that discussions started on the reasons for such a phenomenon, when exactly the same procedure had been used by all teams. The observation of two teams' results (JRC Ispra and ENEL Piacenza, Italy) induced the NDE Ispra laboratories to insist on the possible importance of equipment characteristics. All PISC members insisted on specific studies of the influence of defect characteristics, as well as the role of cladding. These three chapters were the leading PIS laboratory exercises called Parametric Studies.
