Non-destructive testing. Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Edge method Ingestion-build-111333 stainless and heat-resisting steels1 Scope 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
