Popis
BS EN 12680-3:2011
This standard BS EN 12680-3:2011 Founding. Ultrasonic testing is classified in these ICS categories:
- 77.040.20 Non-destructive testing of metals
- 77.140.80 Iron and steel castings
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.
