Founding. Ultrasonic testing - Spheroidal graphite cast iron castings Ingestion-build-264231 Detail of grooves to be1 Scope This European Standard specifies the requirements for the ultrasonic testing of spheroidal graphite cast iron castings and the techniques for determining internal discontinuities by the pulse echo technique. This European Standard does not apply to ultrasonic testing of the nodularity of spheroidal graphite cast irons. This European Standard does not apply to transmission technique. NOTE The transmission technique has insufficient sensitivity
