Founding - Ultrasonic examination - Part 3: Spheroidal graphite cast iron castings (Foreign Standard)

This European Standard specifies the requirements for the ultrasonic examination of spheroidal graphite cast iron castings and the methods for determining internal discontinuities by the pulse-echo technique. This European Standard does not deal with the ultrasonic examination of the nodularity of spheroidal graphite cast irons. This European Standard does not cover the transmission technique. NOTE The transmission technique has insufficient sensitivity to detect the discontinuities found in spheroidal graphite cast iron castings and is used in exceptional cases only.
