Oförstörande provning - Röntgenutrustningar - Karakterisering av brännfläck hos industriella röntgenutrustningar - Del 4: Kantmetod

Status: Gällande

Omfattning
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. The edge method is especially useful for the checking of focal spots under field conditions in order to find changes of the focal spot. It cannot be used for an absolute measurement of the focal spot. For absolute measurements the method according to Annex A is applied.
