Founding - Ultrasonic testing - Part 3: Spheroidal graphite cast iron castings
|Publication Date:||1 November 2011|
|ICS Code (Non-destructive testing of metals):||77.040.20|
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 to detect the discontinuities found in spheroidal graphite cast iron castings and is used in exceptional cases only.
