CEN/TR 14748:2004

This document sets out basic principles and provides recommendations and general guidelines for carrying out qualification of non-destructive tests.
The document deals with methods for qualifying non-destructive tests to determine whether they are capable of attaining their objectives. It applies to all aspects of tests which influence their effectiveness.
The parties involved decide in their own responsibility on the need for a qualification of a non-destructive test. This includes identification of the qualification-team and its technical competence.
There may be a need for qualification when there is a deviation from a European NDT Standard, or when new techniques or methods are to be implemented for which there are no European Standards. Where there is a European NDT Standard which applies, there is no need for qualification.
Table 1 summarises when qualification is required.
