Different basic trends in various industrial branches have created a situation where a consensus about understanding of definitions and possible methods for validation, suitable for NDE, is needed. During discussions with colleagues in America and Europe it became clear that the problems are common to the international NDE profession and that consequently an international approach offers the most realistic pathway to future solutions. This led the DGZfP committee on "Reliability and Validation of NDE Methods" to the proposal of a European-American Workshop entitled "Determination of Reliability and Validation Methods of NDE".
Goal
The principal motivation of the European-American Workshop was to provide a forum for examining the currently available technical and scientific methods for determination of reliability of nondestructive evaluation (NDE) systems and approaches to their validation. Importantly, the Workshop was not intended to address the broad questions of NDE reliability or resolve whether NDE is an art or measurement science. Also, the many legal, cultural, and political aspects of NDE, including certification and braining, were bypassed. The main objective of the Workshop was to come to a common understanding of NDE reliability and different ways of its determination:
This Workshop was held on June 18-20, 1997 in the Federal Institute for Materials Research and Testing (BAM), Berlin, Germany.
The scientific part of the workshop was jointly organized by BAM in Germany and NIST in the US within their framework of long-term cooperation. The technical organization was carried out by DGZfP. The international aspect of the conference is underlined by the institutions we have won as additional cosponsors: ASNT, BlnstNDT, COFREND and ECNDT.
The language of lectures as well as for the proceedings has been English, but for the benefit of the German audience simultaneous interpretation from English into German has been organized.
Attendees
The workshop was attended by nearly 100 participants: 20 from US and Canada, 50 from Germany, and 30 from other European countries, including Great Britain, Netherlands, France, Finland, Spain, Norway, Turkey, Czech Republic, Russia and Ukraine, Hungary, and Sweden. There were 28 invited oral presentations and 20 posters. The last day was devoted to consensus workshops that were attended by all participants.
On behalf of the organizing institutes and the cosponsors we wish now to all NDE experts concerned with reliability and validation to make much use of these proceedings.
