Definitions
- the evaluation table is created by means of assigning the ermit ⁇ telten reflectivity at the specified defect size of Defek ⁇ tes.
- the reflectivity, determined by means of the simulation is correlated with the ver ⁇ used in the simulation defect size.
- the evaluation table is to be understood as a correlation between the reflectivity and the defect size. In other words, a fixed given reflectivity results in exactly one defect size.
- the rating table may be tabulated, wherein a column of the table of reflectance and a white ⁇ tere column is associated with the table, the defect size.
- the amplification corresponds to the detected reflectivity of an ultrasound reflected at the defect.
- the reflected at the De ⁇ fect ultrasound is recognized as a time-dependent Amplitu ⁇ de.
- an evaluation of an ultrasound examination of an object can take place.
- Is ⁇ example for a sensed time-varying amplitude of a Ultra ⁇ sound signal requires a gain of about 83 dB, this corresponds, according to the illustrated diagram of an exemplary defect size of about 1 mm.
- the evaluation table can correspond in their graphi ⁇ rule representation of the diagram shown, detected defects having a defect size below the wavelength of the ultrasound used and their size relationship ⁇ as spare defect size can be determined.

Abstract
La présente invention concerne un procédé pour réaliser une grille d'évaluation pour un contrôle par ultrasons d'un objet, ledit procédé comprenant les étapes suivantes consistant à : - simuler une répartition d'ultrasons sur au moins un défaut ayant une taille de défaut prédéterminée au moyen d'une simulation informatique en deux dimensions ou en trois dimensions, la taille de défaut étant inférieure ou égale à la longueur d'onde des ultrasons et la simulation tenant compte d'une conversion de mode des ultrasons par le défaut ; - déterminer la réflectivité du défaut à partir de la simulation ; et - réaliser la grille d'évaluation en attribuant la réflectivité déterminée à la taille de défaut du défaut déterminée. En outre, l'invention concerne un procédé pour réaliser le contrôle par ultrasons d'un objet, dans lequel on utilise une grille d'évaluation selon l'invention.
