How can the Reliability of Non-Destructive Tests be Estimated?Gábor Klausz, AGMI Material Testing and Quality Control Ltd., Budapest (HU)

KurzfassungIn harmony with the provisions of Standard MSZ EN ISO/IEC 17025 on the General Requirements for the Competence of Testing and Calibration Laboratories the tests must be done using methods and procedures which allow for the compliance with the "requirements for specific use".
The standard methods should be given priority as one can firmly assume that, due to the correct control, the test results will be reliable. In case of a non-standard test method, however, the compliance of the test method with the purpose of the test must be justified, especially when the safety and/or financial consequences of a test performed incorrectly must be accounted for, or the applied test method is complicated or new.
The reliability of the test is basically defined by two factors:
This presentation will highlight an option for estimation the aggregate performance of the NDT equipment and the NDT procedure as required by a given test. The method is based on an ENIQ (European Network of Inspection Qualification) recommendation and the experience gained in pilot tests performed on more than a hundred reference pieces manufactured and collected by AGMI Ltd.
