Calibration and Reference Blocks Used in Nondestructive Ultrasound Examination, According to New European Union Requirements

Résumé

Pursuant international standards such of the European ones, the nondestructive examinations have to be worked out by the most possible accuracy and repeatability, that allow the difference making between the admitted indications, whatever they involve, dump or rejection.
The activity may be carried out with positive results, only, after providing:
- suitable tests and settlements of assay equipment by the agency of calibration and reference blocks;
- insurance for good training of working staff.
With the view of touch of this challenge the CALIST framework program was made.
