EN ISO 19232-4:2013

Non-destructive testing - Image quality of radiographs - Part 4: Experimental evaluation of image quality values and image quality tables (ISO 19232-4:2013)

ISO 19232-4:2013 gives instructions for the determination of image quality values and image quality tables.
If the IQI requirements specified in ISO 19232‑3 cannot be used because, for example, the absorption coefficients of the IQI material and the inspected material differ by more than 30 %, test exposures are necessary to determine acceptance of image quality values. The image quality values achieved by the test exposures are required for all exposures made under the same radiographic conditions.

Zerstörungsfreie Prüfung - Bildgüte von Durchstrahlungsaufnahmen - Teil 4: Experimentelle Ermittlung von Bildgütezahl und Bildgütetabellen (ISO 19232-4:2013)

Dieser Teil von ISO 19232 gibt Anleitungen für die Bestimmung von Bildgütezahlen und Bildgütetabellen.
Wenn die Bildgüteanforderungen nach Teil 3 dieser Norm nicht verwendet werden können, zum Beispiel, weil sich die Absorptionskoeffizienten des BPK Materials und des untersuchten Materials um mehr als 30 % unterscheiden, sind Testaufnahmen notwendig, um die Annahme von Bildgütezahlen sicherzustellen. Die Bildgütezahlen, die durch Testaufnahmen erreicht wurden, werden für alle Durchstrahlungsaufnahmen gefordert, die unter denselben Durchstrahlungsbedingungen gemacht werden.

Essais non destructifs - Qualité d'image des radiogrammes - Partie 4: Évaluation expérimentale des indices de qualité d'image et des tables de qualité d'image (ISO 19232-4:2013)

L'ISO 19232-4:2013 donne les instructions pour déterminer les indices de qualité d'image et les tables de qualité d'image.
S'il n'est pas possible d'appliquer à l'IQI les exigences spécifiées dans l'ISO 19232-3, parce que, par exemple, les coefficients d'absorption du matériau de l'IQI et du matériau soumis à essai diffèrent de plus de 30 %, il est nécessaire d'utiliser des expositions d'essai pour déterminer des indices de qualité d'image acceptables. Les indices de qualité d'image obtenus par les expositions d'essai sont requis pour toutes les expositions faites dans les mêmes conditions radiographiques.

Neporušitveno preskušanje - Kakovost radiografske slike - 4. del: Eksperimentalno ugotavljanje stopnje kakovosti slike in tabel kakovosti slike (ISO 19232-4:2013)

Ta del standarda ISO 19232 podaja navodila za ugotavljanje stopnje kakovosti slike in tabel kakovosti slike. Če zahtev IQI, ki so določene v standardu ISO 19232-3, ni mogoče uporabljati, ker se na primer koeficienta absorbcije materiala IQI in pregledanega materiala razlikujeta za več kot 30 %, so potrebne preskusne izpostavitve, da se ugotovi sprejemljivost stopenj kakovosti slike. Stopnje kakovosti slike, pridobljene s preskusnimi izpostavitvami, so zahtevane za vse izpostavitve, opravljene pod enakimi radiografskimi pogoji.
