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 radiogenes 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.

Overview
SIST EN 12543-4:2000 is a European standard developed by CEN that focuses on non-destructive testing (NDT) by defining the characteristics of focal spots in industrial X-ray systems. Specifically, Part 4 of this standard describes the Edge Method for checking the dimensions of focal spots larger than 0.5 mm in X-ray systems operating up to 500 kV tube voltage. Accurate measurement of focal spot size is critical because the quality and resolution of radiographic images heavily depend on the focal spot properties. This standard ensures consistent, reliable assessment of focal spots to improve NDT results and support industrial safety and quality control.
Key Topics
Focal Spot Characteristics
The focal spot refers to the point on the X-ray tube target where electrons strike to produce X-rays. Its size and intensity distribution directly affect image sharpness and resolution in radiography.Edge Method Technique
The standard specifies using radiographs of sharp edges to determine focal spot dimensions. This method provides two-dimensional intensity distribution analysis essential for verifying imaging quality.Applicable Voltage Range
The procedure applies to X-ray tubes with voltages up to and including 500 kV, covering a broad range of industrial inspection applications.Image Quality Control
By standardizing focal spot measurement, this document supports consistent quality control in NDT processes, helping detect flaws or defects in materials without damaging them.
Applications
SIST EN 12543-4:2000 is applicable in various industries where industrial radiography is employed for non-destructive testing, including:
Manufacturing and Fabrication
Ensuring weld integrity, structural component evaluation, and quality control through precise radiographic inspections.Aerospace and Automotive Industries
Verifying material consistency and detecting internal defects to guarantee component safety and reliability.Petrochemical and Power Generation
Monitoring pipelines, pressure vessels, and reactors to prevent hazardous failures and maintain operational safety.Rail and Infrastructure Maintenance
Inspecting critical metal components, rails, and bridges for cracks or corrosion via high-resolution X-ray imaging.
By implementing the guidelines of EN 12543-4, organizations can accurately assess focal spot characteristics, leading to improved defect detection and more reliable safety assessments.
