Non-destructive testing - Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Part 5: Measurement of the effective focal spot size of mini and micro focus X-ray tubes

Non-destructive testing - Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Part 5: Measurement of the effective focal spot size of mini and micro focus X-ray tubes

This European Standard specifies a method for the measurement of focal spot dimensions within the range of 5 um to 300 um of X-ray systems up to and including 225 kV tube voltage, by means of radiographs of sharp edges. The image quality and the resolution of X-ray images highly depend on the characteristics of the focal spot. The imaging qualities of the focal spot are based on the two dimensional intensity distribution in the object plane. For certification purposes the radiographic technique is used.

Zerstörungsfreie Prüfung - Charakterisierung von Brennflecken in Industrie-Röntgenanlagen für die zerstörungsfreie Prüfung - Teil 5: Messung der effektiven Brennfleckgröße von Mini- und Mikrofokus-Röntgenröhren

Diese Europäische Norm legt ein Verfahren für die Messung von Brennflecken zwischen 5 um und 300 um für Röntgenspannungen bis einschließlich 225 kV mit Hilfe von radiographischen oder radioskopischen Bildern von scharfen Kanten fest. Die Bildgüte und die Auflösung von Röntgenbildern hängen in erster Linie von den Eigenschaften eines Brennfleckes ab. Die Abbildungsqualität eines Brennfleckes basiert auf der zweidimensionalen Intensitätsverteilung in der Objektebene. Zur Zertifizierung wird die radiographische Technik angewendet.

Essais non destructifs - Caractéristiques des foyers émissifs des tubes radiogènes industriels utilisés dans les essais non destructifs - Partie 5: Mesure de la dimension du foyer émissif de tubes radiogènes à mini et micro foyer

La présente norme européenne spécifie une méthode de détermination des dimensions des foyers émissifs dans la gamme de 5 um à 300 um des tubes radiogènes de tension inférieure ou égale à 225 kV, à l'aide d'images radiographiques à bord franc. La qualité et la résolution des images radiographiques dépendent étroitement des caractéristiques du foyer émissif. Les qualités d'imagerie d'un foyer émissif sont fondées sur la répartition bidimensionnelle de la distribution spectrale dans le plan de l'objet. La technique radiographique est utilisée à des fins de certification.
