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 radiogenes industriels utilisés dans les essais non destructifs - Partie 5: Mesure de la dimension du foyer émissif de tubes radiogenes a 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.

Overview
SIST EN 12543-5:2000 is a European Standard developed by CEN, focusing on non-destructive testing (NDT) techniques related to industrial X-ray systems. Specifically, this part 5 of the series addresses the measurement of the effective focal spot size of mini and micro focus X-ray tubes. The standard covers X-ray tubes operating up to 225 kV tube voltage, with focal spot dimensions measured in the range of 5 µm to 300 µm.
The effective focal spot size is a critical parameter since it directly influences the image quality and spatial resolution of radiographic inspections in non-destructive testing applications. This standard specifies a radiographic method using sharp edge images to accurately determine the two-dimensional intensity distribution of the focal spot in the object plane.
Key Topics
Focal Spot Characteristics
Understanding the physical dimensions and intensity distribution of the focal spot in mini and micro focus X-ray tubes is essential for ensuring optimal imaging performance.Measurement Method
The standard defines a radiographic technique involving sharp edge images to measure focal spot size. This method provides precise data on spot dimensions ranging from 5 µm to 300 µm.Tube Voltage Limitations
Applicable to systems with tube voltages up to 225 kV, making it suitable for a wide range of industrial radiography equipment.Image Quality Impact
Emphasizes the relationship between focal spot size and resolution and contrast in radiographic images, key factors in reliable defect detection.Certification and Quality Control
Establishes a consistent measurement standard for certification purposes in quality assurance and compliance within NDT practices.
Applications
