Non-destructive testing - Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Part 4: Edge method

Non-destructive testing - Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Part 4: Edge method

This European standard specifies the checking of focal spot dimensions above 0,5 mm of X-ray systems up to and including 500 kV tube voltage, by means of radiographs of sharp edges. The image quality and the resolution of X-ray images depend highly on the characteristics of the focal spot. The imaging qualities of a focal spot are based on the two dimensional intensity distribution in the object plane.

Zerstörungsfreie Prüfung - Charakterisierung von Brennflecken in Industrie-Röntgenanlagen für die zerstörungsfreie Prüfung - Teil 4: Kantenverfahren

Diese Europäsiche Norm legt ein Verfahren für die Kontrolle von Brennflecken oberhalb 0,5 mm für Röntgenspannungen bis einschließlich 500 kV mit Hilfe von radiographischen Bildern von scharfen Kanten fest. Die Bildgüte und die Auflösung von Röntgenbildern hängen in hohem Maße von den Eigenschaften des Brennfleckes ab. Die Abbildungsqualität eines Brennfleckes basiert auf der zweidimensionalen Intensitätsverteilung der Objekte.

Essais non destructifs - Caractéristiques des foyers émissifs des tubes radiogènes industriels utilisés dans les essais non destructifs - Partie 4: Méthode par effet de bord

La présente norme spécifie la vérification des dimensions des foyers émissifs supérieurs à 0,5 mm des tubes radiogènes dont la tension est inférieure ou égale à 500 kV, à l'aide d'images radiographiques d'un bord franc. La qualité et la résolution des images obtenues par rayonnement X dépendent étroitement des caractéristiques du foyer émissif. Les qualités d'imagerie d'un foyer émissif sont basées sur la répartition bidimensionnelle de la distribution de l'intensité dans le plan de l'objet.

Non-destructive testing - Characterization and verification of ultrasonic phased array equipment - Part 3: Complete systems (ISO 18563-3:2024)
SIST EN ISO 18563-3:2024

This document addresses ultrasonic test systems implementing array probes, for contact technique (with or without wedge) or for immersion technique, with centre frequencies in the range of 0,5 MHz to 10 MHz.
This document provides methods and acceptance criteria for determining the compliance of the complete system (see 3.2). Its purpose is for the verification of the correct operation of the system prior to testing or verification of the absence of degradation of the system.
The methods are not intended to prove the suitability of the system for particular applications but are intended to prove the capability of the complete system (used for an application) to operate correctly according to the settings used. Tests can be performed on individual ultrasonic beams (for phased array technique, see 9.4.4) or on resulting images (for phased array technique and total focusing technique, see 9.4.3).
The tests can be limited to the functions that are intended to be used for a certain application.
This document does not cover the sensitivity setting of the system for a specific application. Nor does it apply to the characterization or verification of the mechanical scanning equipment. It is intended that these items will be covered by the test procedure.
This document does not address the phased array technique using tandem technique.
The characterization of beams, as recommended in case of dead elements or for more in-depth knowledge of the beams, is presented in Annex A. It is not applicable for signal processing technology using arrays.
NOTE            Unless stated otherwise, in this document ‘TFM’ and ‘TFM technique’ refer to the total focusing technique as defined in ISO 23243, and to related techniques, see for example ISO 23865 and ISO 23234.
