(Main)Non-destructive testing - Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Part 2: Pinhole camera radiographic method
Non-destructive testing - Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Part 2: Pinhole camera radiographic method
This European Standard specifies a method for the measurement of focal spot dimensions above 0,2 mm of X-ray systems up to and including 500 kV tube voltage by means of the pinhole camera radiographic method. The voltage applied for this measurement is restricted to 200 kV for visual film evaluation.
The image quality and the resolution of X-ray images depend highly on the characteristics of the focal spot, in particular the size and the two dimensional intensity distribution.
For the characterisation of commercial X-ray tube types (i.e. for advertising or trade) the specific values of Table A.1 are used.
Zerstörungsfreie Prüfung - Charakterisierung von Brennflecken in Industrie-Röntgenanlagen für die zerstörungsfreie Prüfung - Teil 2: Radiographisches Lochkamera-Verfahren
Diese Europäische Norm legt die Messung von Brennfleckmaßen oberhalb von 0,2 mm für Röntgen¬anlagen bis einschließlich 500 kV Röntgenspannung mit dem Lochkamera Verfahren fest. Die für die Messung angewendete Spannung ist für eine visuelle Auswertung des Films auf 200 kV beschränkt.
Die Bildgüte und die Auflösung von Röntgenbildern hängen in hohem Maße von den Eigenschaften des Brennflecks ab, insbesondere von der Größe und der zweidimensionalen Intensitätsverteilung.
Für die Charakterisierung der handelsüblichen Röntgenröhren (d. h. bei Werbung und beim Handel) werden die Vorzugswerte nach Tabelle A.1 verwendet werden.
Essais non destructifs - Caractéristiques des foyers émissifs des tubes radiogènes industriels utilisés dans les essais non destructifs - Partie 2: Méthode radiographique par sténopé
La présente Norme spécifie une méthode de détermination des dimensions des foyers émissifs supérieurs
à 0,2 mm des tubes radiogènes dont la tension est inférieure ou égale à 500 kV, au moyen de la méthode
radiographique par sténopé. La tension appliquée pour cette mesure est limitée 200 kV pour l’examen visuel
du film.
La qualité et la résolution des images radiographiques dépendent étroitement des caractéristiques du foyer
émissif, en particulier de ses dimensions et de la répartition bidimensionnelle de l’intensité.
Pour la caractérisation des tubes radiogènes de type commercial (c’est-à-dire pour publicité ou commerce),
les valeurs spécifiques indiquées dans le Tableau A.1 sont utilisées.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. SIST EN 12543-2:2009
The scanning method (EN 12543-1) is dedicated to those applications where quantitative values for the intensity distribution and spot size are needed, i.e. calibration and image processing purposes.
The radiographic methods (EN 12543-2 and EN 12543-3) describe the traditional techniques and are dedicated for certification purposes and for field applications. A digital detector not only provides focal spot length and width, but also the user with quantitative values for intensity distribution. The digital method may be used as a reference method as in EN 12543-1 Where no pinhole or slit cameras are available in the field, the edge method (EN 12543-4) may be applied. It represents a very simple method for field application.
For micro focus systems, see EN 12453-5. SIST EN 12543-2:2009
The image quality and the resolution of X-ray images depend highly on the characteristics of the focal spot, in particular the size and the two dimensional intensity distribution.
